In areas where it works with no till is common to observe flaws in the burn down of cover crops and/or spontaneous vegetation, which can characterize the insufficient deposition of active ingredient of herbicides. The spray technology is the tool to be used in the planning and execution of burn down, to ensure that products with proven for weed control and coverage, effectiveness are efficiently deposited in biological targets. Two assays were carried out in order to evaluate the efficiency of herbicide applications. At the first it was evaluated the influence of classes drops (very fine droplets and very coarse droplets) and spray volumes (50, 100, 150 and 200 L ha-1) on the effectiveness of cover crop control with use of glyphosate and glyphosate + saflufenacil to control Urochloa ruziziensis and Conyza sp., respectively. The classes of droplets influence the control of Urochloa ruziziensis. The reduction on spray volume increased the possibility of sprouts on Conyza sp. On the second experiment it was investigated the efficiency of two spray application volumes (50 and 200 L ha-1) at different times of day (4:30, 10:30, 16:30 and 22:30 pm) on burn down of Urochloa ruziziensis and spontaneous vegetation. The efficacy of glyphosate in cover crops is not influenced by schedules of spray.
Em áreas onde se trabalha com Plantio Direto é comum observar-se falhas na dessecação das plantas de cobertura e/ou vegetação espontânea, o que pode caracterizar a deposição em quantidade insuficiente do ingrediente ativo do herbicida. A tecnologia de aplicação é a ferramenta a ser utilizada no planejamento e execução da dessecação, a fim de garantir que produtos com eficácia comprovada para o controle de plantas daninhas e de cobertura, sejam eficientemente depositados nos alvos biológicos. Visando maximizar a eficácia de herbicidas por meio de aplicações eficientes foram realizados dois experimentos. No primeiro foi avaliada a influência das classes de gotas (gotas muito fina e gotas muito grossa) e volumes de aplicação (50, 100, 150 e 200 L ha-1) no controle das coberturas vegetais, com uso de glyphosate e glyphosate + saflufenacil para controle de Urochloa ruziziensis e Conyza sp., respectivamente, no qual concluiu-se que as classes de gotas influenciam no controle de Urochloa ruziziensis e a redução do volume de aplicação aumenta a possibilidade de rebrotes de Conyza sp.. No segundo experimento avaliou-se a eficiência da aplicação em dois volumes de aplicação (50 e 200 L ha-1) em diferentes horários do dia (4:30, 10:30, 16:30 e 22:30 horas) na dessecação de Urochloa ruziziensis e vegetação espontânea. Conclui-se que a eficácia de glyphosate nas coberturas vegetais não sofre influência de horários de aplicação.

Full textEntomopathogenic fungi of the genera Metarhizium, Beauveria and Isaria (order Hypocreales) are associated to the soil where they survive saprofitically or as endophytes of the plants root system. Information on the species composition and its diversity, distribution and association of these fungi with different types of crops and native vegetation are scarce in Brazil. The present study was carried out to compare the abundance of entomopathogenic fungi and the genetic diversity of Metarhizium spp. Isolated from soil samples from annual and perennial crops and native vegetation in five Brazilian states that represent the biomes Amazon, Cerrado, Caatinga, Atlantic Forest and Pampa, in two seasons (wet and dry) in the years 2012 and 2013. The isolation of fungi was performed with selective medium and \"Insect bait\" using Galleria mellonella and Tenebrio molitor. DNA sequences of the region MzIGS3 were used in genetic diversity studies of Metarhizium spp. Representatives haplotypes revealed in the diversity analysis had the 5\'-TEF region sequenced for species identification. Entomopathogenic fungi were isolated from 86% of 1,056 soil samples and Metarhizium was the predominant genus (66% of soil samples), followed by Beauveria (41.9%) and Isaria (10.8%). In general, the highest densities of entomopathogenic fungi were obtained in the Amazon and Cerrado biomes and the lowest densities were detected in the Caatinga biome. Metarhizium spp. was detected in a greater number of soil samples from native vegetation and annual and perennial crops of Cerrado. The frequency of Isaria spp. was low in soil samples being detected in a greater number of soils with annual crops and native vegetation in the Amazon and Caatinga. Metarhizium spp. was usually found in a greater number of samples collected during the wet season compared to the collections in the dry season. On the other hand, Beauveria spp. was higher in the dry season. The diversity of isolates of Metarhizium spp. from areas of native vegetation was greater than that obtained from annual and perennial crops. Six lineages were found in this study; M. robertsii, M. anisopliae, M. pingshaense and three indeterminate species. M. robertsii was the predominant (65% of isolates) found in areas with native vegetation and in the annual and perennial crops of the five biomes. Metarhizium sp. indet. 1 showed the greatest haplotype diversity among the strains studied. A new strain, not characterized taxonomically, Metarhizium sp. indet. 3, was found predominantly in the Caatinga. Only in the Amazon, all lineages were found. The knowledge on species composition of entomopathogenic fungi as well as about phylogeny, diversity and distribution of haplotypes of Metarhizium spp. in Brazilian soils, generated in this study, may be useful for the development of strategies for conservation and maximization of natural biological control of pests.

Full textThe jabuticaba tree is a specie of difficult vegetative propagation and an efficient protocol has not been defined yet. The aim of this work was to test the efficiency of vegetative propagation techniques for jabuticaba tree and develop an efficient protocol for disinfection and initial establishment of in vitro explants. It was tested the rooting potential of wood cutting of P. cauliflora, utilizing four concentrations of Indolbutiric Acid - IBA (0, 2000 , 4000 and 6000 mg L-1) and two procedures (cross section and cuttings girdling); and the rooting potential of softwood terminal cuttings of P. cauliflora, utilizing five concentrations of IBA (0, 2000, 4000, 6000 and 8000 mg L-1) in two periods of implantation (October and December 2007). The rooting potential of cuttings was evaluated after 180 days of the beginning of the experiments. It was also tested the compatibility of grafting of three species of jabuticaba tree (P. cauliflora, P. trunciflora, P. jaboticaba) on rootstocks of P. cauliflora, and two periods (May and August). It was evaluated the survival percentage of grafting, number and size of shoots, after 90 days of the beginning of the experiment. For air layering techniques, it was tested two diameters of branch (1.0-1.5 cm and 2.0-2.5 cm) and two widths of girdling (1.5 cm and 3.0 cm) in P. cauliflora. It was evaluated the rooting percentage, and number and size of roots, 180 days after the beginning of the experiment. It was also tested the period of immersion (5, 10, 15 minutes) in 1,25% sodium hypochlorite solution in the in vitro establishment of shoot and root of the seedlings explants of P. trunciflora. After 45 days of incubation it was evaluated the percentage of contamination and number of shoots and leaves in each explant. It was observed that rooting of wood cutting is dependent of application of IBA, so the biggest rooting percentage (50%) was obtained in biggest concentration of IBA (6000mg L-1) associated with cross section. For the softwood terminal cuttings, the rooting was small (maximum of 10%). Meantime, exist the potential of rooting, and, changes of technique must be tested for maximization. The grafting and the air layering techniques are recommended for jabuticaba tree propagations, because this techniques provide high percentage of plants formation. There is visible compatibility between the three species grafted on rootstocks of P. cauliflora. The utilization of grafts collected from plants in fructification should be avoided, because they reduce the percentage of plants establishment. In air layering techniques, branches with diameter of 2.0 cm provides higher percentage of rooting and the biggest number and size of roots in relation of branches with small diameter (1.0 to 1.5 cm). The utilization of less time in immersion (five minutes) in 1,25% sodium hypochlorite solution is efficient for shoots explants disinfestations of jabuticaba tree seedlings and allows the initial in vitro establishment, providing development of shootings.

Full textLandwirtschaft ist eine der wichtigsten menschlichen Aktivitäten, sie stellt Nahrungsmittel und andere landwirtschaftliche Produkte für weltweit 7 Milliarden Menschen zur Verfügung und ist in den Ländern Afrikas südlich der Sahara von besonderer Bedeutung. Die Mehrheit der afrikanischen Bevölkerung bestreitet ihren Lebensunterhalt in der Landwirtschaft und wird von Klimaänderungen stark betroffen sein. Die Doktorarbeit ist durch die Frage motiviert, wie sich von Klimamodellen vorhergesagte Temperaturerhöhungen und sich verändernde Niederschlagsverteilungen auf die landwirtschaftliche Vegetation auswirken werden. Die Forschungsfragen in diesem Kontext beschäftigen sich mit regionalen Unterschieden von Klimaänderungen und ihren Auswirkungen auf die Landwirtschaft und mit möglichen Anpassungsstrategien die mit geringem technischem Aufwand genutzt werden können. In diesem Zusammenhang wird schnell deutlich, dass Daten über die komplexen landwirtschaftlichen Systeme in Afrika südlich der Sahara häufig nur selten vorhanden sind, aus fragwürdigen Quellen stammen oder von schlechter Qualität sind. Die Methoden und Modelle zur Untersuchung der Auswirkungen von Klimaänderungen auf die Landwirtschaft werden zudem ausschließlich in Europa oder Nordamerika entwickelt and häufig in den temperierten Breiten aber seltener in tropischen Gebieten angewendet. Vor allem werden globale, dynamische Vegetationsmodelle in Kombination mit Klimamodellen eingesetzt um Änderungen in der landwirtschaftlichen Produktion auf Grund von Klimaänderungen in der zweiten Hälfte des 21.Jahrhunderts abzuschätzen. Die Ergebnisse der Arbeit zeigen einen mittleren Ertragsrückgang für die wichtigsten landwirtschaftlichen Pflanzen um 6% bis 24% bis 2090 je nach Region, Klimamodell und Anpassungsstrategie. Dieses Ergebnis macht deutlich, dass Landwirte die negativen Folgen von Klimaänderungen abschwächen können, wenn sie die Wahl der Feldfrucht, die Wahl des Anbausystems und den Aussaattermin an geänderte Klimabedingungen anpassen. Die Arbeit stellt methodische Ansätze zur Berechung des Aussaattermins in temperierten und tropischen Gebieten (Kapitel 2) sowie zur Simulation von Mehrfachanbausystemen in den Tropen vor (Kapitel 3). Dabei werden wichtige Parameter für das globale, dynamische Vegetationsmodell LPJmL überprüft und neu berechnet. Es zeigt sich, dass das südliche Afrika und die Sahelregion die am stärksten betroffenen Regionen sind, vor allem aufgrund von Niederschlagsänderungen, weniger aufgrund von Temperaturerhöhungen. In den meisten anderen Teilen, vor allem Zentral- und Ostafrikas bedingen Temperaturerhöhungen Rückgänge der Erträge (Kapitel 4). Diese Arbeit leistet einen wichtigen und umfassenden Beitrag zum Verständnis der Auswirkung von Klimaänderung auf die landwirtschaftliche Vegetation und damit zu einem großen Teil auf die Lebensgrundlage von afrikanischen Landwirten.

Full textVegetation parameters, as the leaf area index (LAI) and the ground cover (GC) are commonly related to biosphere processes, being used in models to estimate yield and crop water requirements. Several direct and indirect methods have been developed in the past decades to determine the LAI. However, a simple approach to assess this parameter is still missing. In this study we tested the operability and precision of different methods to calculate the LAI of 6 and 20 year old olive trees (Arbequina and Cobrançosa), under irrigated and non-irrigated conditions in the region of Alentejo. The average LAI on a projected area basis was estimated to be 5.88 and 2.75 m2 m-2 at the irrigated and non-irrigated sites, respectively, corresponding to 1.01 and 1.05 m2 m-2 on a total area basis. Furthermore, a tool was introduced to simplify the decision making between the use of the LAI and the GC. The determination of the GC is much easier than the LAI in practical uses. The average GC was 5.7 m2 under irrigated and 18.0 m2 under non-irrigated conditions. A detailed comparison between direct and indirect methods is given and the future prospective of the decision making tool is discussed.

Full textMeasuring leaf and canopy characteristics from remote sensing acquisitions is an effective and non destructive way to monitor crops both for decision making within the smart agriculture practices or for phenotyping under field conditions to improve the selection efficiency. With the advancement of computer computing power and the increasing availability of high spatial resolution images, retrieval methods can now benefit from more accurate simulations of the Radiative Transfer (RT) models within the vegetation. The objective of this work is to propose and evaluate efficient ways to retrieve leaf and canopy characteristics from close and remote sensing observations by using RT models based on a realistic description of the leaf and canopy structures. At the leaf level, we first evaluated the ability of the different versions of the PROSPECT model to estimate biochemical variables like chlorophyll (Cab), water and dry matter content. We then proposed the FASPECT model to describe the optical properties differences between the upper and lower leaf faces by considering a four-layer system. After calibrating the specific absorption coefficients of the main absorbing material, we validated FASPECT against eight measured ground datasets. We showed that FASPECT simulates accurately the reflectance and transmittance spectra of the two faces and overperforms PROSPECT for the upper face measurements. Moreover, in the inverse mode, the dry matter content estimation is significantly improved with FASPECT as compared to PROSPECT. At the canopy level, we used the physically based and unbiased rendering engine, LuxCoreRender to compute the radiative transfer from a realistic 3D description of the crop structure. We checked its good performances by comparison with the state of the art 3D RT models using the RAMI online model checker. Then, we designed a speed-up method to simulate canopy reflectance from a limited number of soil and leaf optical properties. Based on crop specific databases simulated from LuxCoreRender for wheat and maize and crop generic databases simulated from a 1D RT model, we trained some machine learning inversion algorithms to retrieve canopy state variables like Green Area Index GAI, Cab and Canopy Chlorophyll Content (CCC). Results on both simulations and in situ data combined with SENTINEL2 images showed that crop specific algorithms outperform the generic one for the three variables, especially when the canopy structure breaks the 1D turbid medium assumption such as in maize where rows are dominant during a significant part of the growing season

Full textThe expansion of agricultural areas has led to the loss of biodiversity due to the reduction of natural and semi-natural habitats in agricultural landscapes. With the increase of agricultural production in the world, environmentally sound techniques are increasingly discussed that allow a sustainable management of surrounding habitats. The effects of these habitats on the population of insect pests and their natural enemies are still poorly understood. The objective of this thesis was to understand the effects of natural and semi-natural environments on the population of insect pests and natural enemies in tropical (Brazil) and temperate (France) regions. In Brazil (Chapter II) the effect of the distance of fragments on the population of predatory and omnivorous ants in sugarcane was evaluated. The results showed that the species richness decrease with distance from forest fragments and that the dominance of the species Dorymyrmex bruneus and Pheidole oxyops increase. Ant species colonizing sugarcane fields were also found in forest fragments suggesting that the latter habitats are shelters for predatory ant species during periods of disturbance such as sugarcane harvest or soil tillage. This was confirmed by stronger differences in ant communities after sugarcane harvest (dry season) than four months later /(rainy season) when absence of disturbance allowed re-colonization by ants. There was also a difference in the richness of ant species between different fragment types (river valleys and plateaus). In France, the effect of wildflower strips, spontaneous vegetation and grass strips on the community of natural enemies and the regulation of the rosy apple aphid Dysaphis plantaginaea (Chapter III) were evaluated. Concerning major natural enemies, our results showed a higher density of hoverflies compared with other strip types but no difference for ladybirds (coccinelidae). No differences in natural enemy densities were observed inside orchards. Aphid number was higher close to the margins suggesting that colonization from margin strips may counteract positive regulatory effects of natural enemies. Positive effects of strip margin vegetation on regulation of apple pests require a movement of natural enemies into the orchard. We tested the movements of generalist predators by labelling margin strips with egg protein and we checked whether they fed on pest insects using genetic marker analysis of codling (Cydia pomonella) moth genes inside predators (chapter IV). The results showed that few individuals were moving from the field margins into the orchard. However, 25% of the captured predators fed on C. pomonella still indicating a high level of natural regulation. In conclusion, the limited movement of predators from margin strips into orchards may explain the absence of differences between strip treatments in orchard pest regulation (aphids). Natural and semi-natural habitats can contribute to pest control at the margins of crops, but in apple orchards this effect strongly decreased with distance

Resumo: O presente trabalho descreve um estudo sobre estimativa de safras cujo principal objetivo foi criar uma metodologia de integração de dados de produção, dados espectrais e indicadores meteorológicos por meio de redes neurais artificiais, estabelecendo correlações entre índices de vegetação e de produtividade, com o propósito de estimar a produtividade de cana-de-açúcar. O estudo foi dividido em duas etapas: a primeira correspondeu à obtenção e organização dos dados em um banco de dados com padrões de entrada/saída; a segunda, à implementação e ajuste das redes neurais, por meio de ensembles. O estudo foi realizado em unidades amostrais de produção de uma usina sucroalcooleira no município de Araras-SP. A primeira etapa consistiu na obtenção dos coeficientes de produtividade (kp), por meio da inversão do modelo agrometeorológico de Doorenbos e Kassam (1979), a partir da determinação do balanço hídrico. O resultado deste procedimento mostrou a sensibilidade do coeficiente à variabilidade da produtividade nos talhões. Os dados espectrais das imagens Landsat 7 ¿ ETM+ foram obtidos de correlações descritas na literatura estabelecidas entre o Índice de Vegetação Greenness (GVI), a banda do infravermelho próximo (B4) e a produtividade da cana-de-açúcar. A estratégia para treinamento dos ensembles foi baseada no aprendizado supervisionado aplicado a uma arquitetura Multilayer Perceptron (MLP), com uma camada escondida, método de aprendizado de 2ª ordem e feedforward. Na etapa de treinamento e validação, as redes neurais tiveram como variáveis de entrada os valores de kp, GVI e B4, e como variável de saída a produtividade, que definiram os padrões de entrada/saída. A fase de teste consistiu em implementar a metodologia em um grupo de padrões de entrada não utilizados nos treinamentos. Os resultados mostraram valores de EQM entre 0,03 e 0,51 ton/ha, enquanto que a estimativa da usina errou em média 9,93 ton/ha, o que garantiu o correto ajuste da rede neural quanto à topologia, ao número de iterações e aos algoritmos de aprendizagem. Esta etapa mostrou a capacidade de generalização da rede neural, já que os treinamentos foram realizados a partir de unidades amostrais. O estudo ratificou a aplicação desta metodologia na determinação da estimativa de produtividade de cana-deaçúcar, empregando-a como técnica complementar aos atuais métodos de estimativa agrícola, sugerindo a ampliação da escala de aplicação para o ambiente de produção da usina
Abstract: The present thesis describes a study on crop forecast. Its main purpose was to create a methodology for integrating production, spectral and meteorological data indicators through artificial neural networks, establishing correlations between vegetation index and yield coefficients, aiming at the estimate of sugarcane yield. The study was divided in two parts: the first corresponded to obtaining and organizing data in a database with input/output default; the second corresponded to the implementation and adjustment of the neural network. The study was carried out in sample production units (fields) of a sugarmill agricultural area located in the municipality of Araras-SP, Brazil. The first part consisted in obtaining yield coefficients (kp) through the inversion of the Doorenbos-Kassam (1979) agrometeorological model, based on the determination of the water balance. The result of this procedure showed the coefficient¿s sensitivity to the variability of yield within the sample fields. The spectral data of the Landsat 7 ¿ ETM+ images were obtained from correlations, available in scientific literature, between the Greenness Vegetation Index (GVI), near infrared band, and sugarcane yield. The strategy for training the neural network was based on supervised learning applied to a Multilayer Perceptron (MLP) architecture, with a hidden layer, second order learning method and feedforward. For the training and validation stage, the neural network had as input variables kp, GVI and B4 values, and as output variable the yield, both obtained in the input/output database. The test stage consisted of implementing the methodology in a set of input patterns not used for the trainings. The results showed Mean Square Error (MSE) values between 0,03 and 0,51 ton/ha, while the average error of the sugarmill estimates were 9,93 ton/ha, which showed the correct adjustment of the network concerning topology, number of iterations and learning algorithms. This showed the generalization capacity of the neural network once the trainings were carried out based on sample units. The study ratified the application of this methodology for determining sugarcane yield estimate, employing it as a complementary technique to the present methods of agricultural forecast, suggesting the increase of the application scale to a broader area of the sugarmill production environment

L'expansion des zones agricoles a conduit à la perte de biodiversité due à la réduction des habitats naturels et semi-naturels dans les paysages agricoles. Avec l'augmentation de la production agricole dans le monde, des techniques écologiquement rationnelles sont de plus en plus discutées qui permettent une gestion durable des habitats environnants. Les effets de ces habitats sur la population des insectes nuisibles et de leurs ennemis naturels sont encore mal connus. L'objectif de cette thèse était de comprendre les effets des environnements naturels et semi-naturels sur la population des insectes nuisibles et des ennemis naturels dans les régions tropicales (Brésil) et tempérées (France). Au Brésil (chapitre II), on a évalué l'effet de la distance des fragments sur la population de fourmis prédatrices et omnivores dans la canne à sucre. Les résultats montrent que la richesse en espèces diminue avec la distance des fragments forestiers et que la prédominance des espèces Dorymyrmex bruneus et Pheidole oxyops augmente. Des espèces de fourmis colonisant les champs de canne à sucre ont également été trouvées dans des fragments forestiers, ce qui suggère que ces derniers habitats sont des refuges pour les espèces de fourmis prédatrices pendant les périodes de perturbation comme la récolte de la canne à sucre ou le travail du sol. Cela a été confirmé par des différences plus fortes dans les communautés de fourmis après la récolte de la canne à sucre (saison sèche) que quatre mois plus tard / (saison des pluies) quand l'absence de perturbation a permis la re-lonosiation par les fourmis. Il y avait aussi une différence dans la richesse des espèces de fourmis entre les différents types de fragments (vallées fluviales et plaines). En France, on a évalué l'effet des bandes de fleurs sauvages, de la végétation spontanée et des bandes d'herbe sur la communauté des ennemis naturels et la régulation du puceron de la pomme rosâtre Dysaphis plantaginaea (chapitre III). En ce qui concerne les principaux ennemis naturels, nos résultats ont montré une densité plus élevée de hoverflies par rapport à d'autres types de bande, mais aucune différence pour les coccinelles (coccinelidae). Cependant, aucune différence de densité naturelle de l'ennemi n'a été observée à l'intérieur des vergers. Le nombre de pucerons était plus élevé près des marges, ce qui suggère que la colonisation à partir des bandes marginales peut contrecarrer les effets régulateurs positifs des ennemis naturels. Les effets positifs de la végétation de la marge de bande sur la régulation des ravageurs de la pomme nécessitent un mouvement d'ennemis naturels dans le verger. Nous avons testé les mouvements des prédateurs généralistes en étiquetant les bandes de marge avec des protéines d'oeufs et nous avons vérifié si elles se nourrissaient d'insectes nuisibles en utilisant l'analyse de marqueurs génétiques des gènes de papillon (Cydia pomonella) à l'intérieur des prédateurs (chapitre IV). Les résultats ont montré que peu de personnes se déplaçaient des marges de champ dans le verger. Cependant, 25% des prédateurs capturés se nourrissaient de C. pomonella indiquant encore un haut niveau de régulation naturelle. En conclusion, le mouvement limité des prédateurs à partir des bandes de marges dans les vergers peut expliquer l'absence de différences entre les traitements de bandes dans la régulation des ravageurs du verger (pucerons). Les habitats naturels et semi-naturels peuvent contribuer à la lutte contre les ravageurs en marge des cultures, mais dans les vergers de pommiers cet effet a fortement diminué avec la distance.
A expansão das áreas agrícolas levou à perda de biodiversidade devido à redução dos habitats naturais e semi-naturais nas paisagens agrícolas. Com o aumento da produção agrícola no mundo, são cada vez mais discutidas técnicas ambientais que permitem uma gestão sustentável dos habitats do entorno. Os efeitos desses habitats sobre a população de insetos-pragas e seus inimigos naturais ainda são mal compreendidos. O objetivo desta tese foi compreender os efeitos dos ambientes naturais e semi-naturais na população de insetos-pragas e inimigos naturais nas regiões tropicais (Brasil) e temperadas (França). No Brasil (Capítulo II) foi avaliado o efeito da distância de fragmentos sobre a população de formigas predadoras e omnívoras em cana-de-açúcar. Os resultados mostraram que a riqueza de espécies diminui com a distância dos fragmentos florestais e que a dominância das espécies Dorymyrmex bruneus e Pheidole oxyops aumenta. As espécies de formigas que colonizam áreas de cana-de-açúcar também foram encontradas em fragmentos de florestas, sugerindo que estes últimos são abrigos para espécies de formigas predatórias durante períodos de perturbação como colheita de cana-de-açúcar ou preparo do solo. Isto foi confirmado por diferenças mais fortes nas comunidades de formigas após a colheita da cana (estação seca) do que quatro meses depois (estação chuvosa) quando a ausência de perturbação permitiu recolonização por formigas. Houve também uma diferença na riqueza de espécies de formigas entre diferentes tipos de fragmentos (vales de rios e planícies). Na França, foi avaliado o efeito de faixas de flores silvestres, vegetação espontânea e gramíneas na comunidade de inimigos naturais e a regulação do pulgão cinza Dysaphis plantaginaea (Capítulo III). No que diz respeito aos principais inimigos naturais, os nossos resultados mostraram uma maior densidade de sirfideos nas faixas de flores em comparação com outros tipos de faixas, mas nenhuma diferença para joaninha (Coccinelidae). Não foram observadas diferenças nas densidades de inimigos naturais dentro dos pomares. O número de afídeos foi maior perto das margens, sugerindo que a colonização das faixas nas margens pode neutralizar os efeitos reguladores positivos dos inimigos naturais. Os efeitos positivos da vegetação nas faixas da margem na regulação de pragas da maçã requerem um movimento de inimigos naturais no pomar. Nós testamos os movimentos de predadores generalistas marcando as faixas das margens com proteína de ovo e verificamos se eles se alimentavam de insetos pragas usando a análise de marcadores moleculares de genes de mariposas (Cydia pomonella) nos predadores (capítulo IV). Os resultados mostraram que poucos indivíduos se movimentaram das margens do campo para o pomar. No entanto, 25% dos predadores capturados alimentados com C. pomonella ainda indicam um alto nível de regulação natural. Em conclusão, o movimento limitado de predadores das faixas de plantas nas margens em pomares pode explicar a ausência de diferenças entre os tratamentos na regulação de pragas do pomar (pulgões). Habitats naturais e semi-naturais podem contribuir para o controle de pragas nas margens das culturas, mas em pomares de maçã este efeito diminuiu fortemente com a distância.
The expansion of agricultural areas has led to the loss of biodiversity due to the reduction of natural and semi-natural habitats in agricultural landscapes. With the increase of agricultural production in the world, environmentally sound techniques are increasingly discussed that allow a sustainable management of surrounding habitats. The effects of these habitats on the population of insect pests and their natural enemies are still poorly understood. The objective of this thesis was to understand the effects of natural and semi-natural environments on the population of insect pests and natural enemies in tropical (Brazil) and temperate (France) regions. In Brazil (Chapter II) the effect of the distance of fragments on the population of predatory and omnivorous ants in sugarcane was evaluated. The results showed that the species richness decrease with distance from forest fragments and that the dominance of the species Dorymyrmex bruneus and Pheidole oxyops increase. Ant species colonizing sugarcane fields were also found in forest fragments suggesting that the latter habitats are refuges for predatory ant species during periods of disturbance such as sugarcane harvest or soil tillage. This was confirmed by stronger differences in ant communities after sugarcane harvest (dry season) than four months later (rainy season) when absence of disturbance allowed re-colonosiation by ants. There was also a difference in the richness of ant species between different fragment types (river valleys and plateaus). In France, the effect of wildflower strips, spontaneous vegetation and grass strips on the community of natural enemies and the regulation of the rosy apple aphid Dysaphis plantaginaea (Chapter III) were evaluated. Concerning major natural enemies, our results showed a higher density of hoverflies in wild flower strips compared with other strip types but no differences for ladybirds (coccinelidae). However, no differences in natural enemy densities were observed inside orchards. Aphid number was higher close to the margins suggesting that colonization from margin strips may counteract positive regulatory effects of natural enemies. Positive effects of strip margin vegetation on regulation of apple pests require a movement of natural enemies into the orchard. We tested the movements of generalist predators by labelling margin strips with egg protein and we checked whether they fed on pest insects using specific genetic marker of the codling moth (Cydia pomonella) (chapter IV). The results showed that few individuals were moving from the field margins into the orchard. However, 25% of the captured predators fed on C. pomonella still indicating a high level of natural regulation. In conclusion, the limited movement of predators from margin strips into orchards may explain the absence of differences between strip treatments in orchard pest regulation (aphids). Natural and semi-natural habitats can contribute to pest control at the margins of crops, but in apple orchards this effect strongly decreased with distance.

The management of weeds is complex and comprises a major component of the production cost of most cultures. Growing cover crops is one of the forms of management to reduce weeds competing. Agrobiodiversity, including the biota and the surrounding properties, constituting a cultural and natural capital able to provide ecosystem services. In this context, we developed a study to investigate the potential of wild species Crotalaria incana (rattlesnake rattle or Xique-Xique) and Diodia saponariifolia (Poaia the swamp), which occur in a nearby landscape the Atlantic Forest fragments in the River Basin region Guapi-Macacu-RJ, as part of sustainable agro-ecosystems, constituting strategy to reduce the use of herbicides and enhancing local biodiversity. This potential was assessed in C. incana through phenological studies of plant height, crown diameter, number of branches, presence of inflorescence and number of pods along the cycle and at different times, October, January, February and March. Also evaluated in its interaction with the climate and planting dates. It was found that the planting October C. incana had the longest growing season, low seed production. In the planting in February, the performance of C. incana was good in both parameters; while planting in March, C. incana demonstrated lower performance for mass production and seeds. Preliminary assessments of total biomass and macronutrients, indicate the potential of C. incana as a cover crop that needs to be better investigated. As for D. saponariifolia, a creeping species characterized as macrophyte, evaluations were made of soil coverage percentage after its introduction, compared to the most frequently dominant families in the system, Poaceae and Cyperaceae. Subsequently evaluated the seed bank behavior in this same area after being introduced (experimental area), compared to natural area, which was already established spontaneously. We observed a cooling populations of Poaceae and Cyperaceae after the introduction D. saponariifolia. The spontaneous seed bank revealed a reduction in the expression of these families, important competitors in the system. Possible allelopathic effect of D. saponariifolia in suppressing spontaneous, was evaluated by bioassay with the soil of the natural area where D. saponariifolia prevails spontaneously. In this ground sesame seeds were germinated Sesame indicu L. () in 15-cell trays 3 treatments (T1, T2, T3). T1, activated carbon was added to neutralize allelopathic effects harmful to the development of seedlings. T2, do not add anything. In T3 (control) used a soil adjacent area without the presence of individuals D. saponariifolia. There was no significant difference in the development of seedlings in 3 treatments, indicating no evidence of allelopathic effects of D. saponariifolia on Sesame germination. We can infer that the suppression of processes D. saponariifolia are only for "muffling".
O manejo de plantas espont?neas ? complexo e comp?e um dos principais componentes do custo de produ??o da maioria das culturas. O cultivo de plantas de cobertura ? uma das formas de manejo para redu??o das plantas espont?neas competidoras. Neste contexto desenvolveu-se um estudo com objetivo de investigar o potencial das esp?cies espont?neas Crotalaria incana (Xique-Xique) e Diodia Saponariifolia (Poaia do brejo), que ocorrem em uma paisagem pr?xima a fragmentos de Mata Atl?ntica, na regi?o da Bacia do Rio Guapi-Macacu-RJ, como parte integrante de agroecossistemas sustent?veis, constituindo estrat?gia para redu??o do uso de herbicidas e incremento da biodiversidade local. Este potencial foi avaliado em C. incana, atrav?s de estudos fenol?gicos de altura da planta, di?metro de copa, n?mero de ramos, presen?a de infloresc?ncia e n?mero de vagens ao longo do ciclo e em diferentes ?pocas Outubro, Janeiro, Fevereiro e Mar?o). Avaliou-se tamb?m sua intera??o com o clima e ?pocas de plantio. Constatou-se que no plantio de Outubro, C. incana teve o ciclo vegetativo mais longo, com pouca produ??o de sementes. J? no plantio em Fevereiro, o desempenho de C. incana foi bom em ambos par?metros; enquanto no plantio de Mar?o, C. incana demonstrou menor desempenho tanto para produ??o de massa como de sementes. Avalia??es preliminares de macronutrientes totais e biomassa indicam bom potencial de C. incana a ser melhor investigado. Quanto ? D. Saponariifolia, uma esp?cie rasteira caracterizada como macr?fita, foram feitas avalia??es de porcentagem de cobertura do solo ap?s sua introdu??o, comparando com as fam?lias mais frequentemente dominantes no sistema, Poaceae e Cyperaceae. Posteriormente avaliou-se o comportamento do banco de sementes nesta mesma ?rea ap?s ser introduzida (?rea experimental), comparando com ?rea natural onde j? estava estabelecida espont?neamente. Observou-se um arrefecimento das popula??es de Poaceae e Cyperaceae ap?s a introdu??o D. saponariifolia. O banco de sementes de espont?neas revelou uma redu??o na express?o destas fam?lias e de Asteraceae, importantes competidoras no sistema. Poss?vel efeito alelop?tico de D. saponariifolia na supress?o de espont?neas, foi avaliado atrav?s de biosensaio com o solo da ?rea natural, onde D. saponariifolia predomina espontaneamente. Neste solo foram germinadas sementes de Sesamo indicu L. (Gergelim) em bandejas de 15 c?lulas, com 3 tratamentos (T1,T2,T3). Em T1, adicionou-se carv?o ativado, que neutralizaria efeitos alelop?ticos prejudiciais ao desenvolvimento das pl?ntulas. Em T2, n?o se adicionou nada. Em T3 (controle) utilizou-se um solo da ?rea adjacente, sem presen?a de indiv?duos de D. saponariifolia. N?o houve diferen?a significativa no desenvolvimento das pl?ntulas nos 3 tratamentos, indicando n?o haver evid?ncias de efeitos alelop?ticos de D. saponariifolia na germina??o de Gergelim. Podemos inferir que os processos de supress?o de D. saponariifolia sejam apenas por ?abafamento?.

Full textThe cultivation of black pepper (Piper nigrum L.) for commercial purposes, in the State of Espírito Santo, began in the 70s, being the cv. Bragantina currently the most representative among crops in this State. The urge to keep its status in the cultivation of this specific kind of spice demands, urgently, further studies and therefore, thorough research using appropriate technologies for the region. In this sense the quality of mother plants begins with the production of seedlings of excellence. Despite the experience of the greenhouse workers in the region to produce nursery plants by cuttings, the steps in this process should be thoroughly inspected to ensure maximum efficiency. The study aimed to investigate the system of production of black pepper cuttings, including the efficiency of substrates used in the nurseries. It was requested to the Ministério da Agricultura, Pecuária e Abastecimento (MAPA) the location of nurseries in accordance with applicable law and based on the information provided technical visits were made to 11 nurseries, recorded through a questionnaire. Samples of the substrates used in the production of seedlings were collected. The responses from the questionnaires were tabulated and converted into graphs of relative frequency for better contextualization of the situation, and the substrates were used to assemble a factorial experiment 11 (substrates) x 2 (presence or absence of 3-butyric acid (IBA)) aiming to evaluate the rooting of black pepper grow Bragantina conducted in randomized block design with four replications of 16 cuttings in a greenhouse located in the Centro Universitário Norte do Espírito Santo, in São Mateus-ES. It was found that there is no uniformity in seedling production, in the nurseries infrastructure nor the techniques used. The differences are related to the origin of the parental plants, plant propagation, and management for seedling growth, ensuring, through analysis, the difference in chemical composition, physical and biological substrates of, mainly influenced by the diversity of the source of organic matter and the use or not of lime and fertilizers. It was concluded that, despite all the nurseries are registered at the Registro Nacional de Sementes e Mudas (RENASEM) and comply with the legal requirements in force, we still need to research and study the differences so that the production of black pepper cuttings can exceed its excellence in results. The quality of the rooting of black pepper on the substrates used by nurserymen, was statistically analyzed by multiple comparisons (Tukey or Scott-Knott in 5% level of probability), and it was found significant increase in the percentage of rooting with the use of IBA and also a reasonable difference in the quality of the rooting between substrates
O cultivo da pimenteira-do-reino (Piper nigrum L.) para fins comerciais, no Espírito Santo, iniciou-se na década de 70, sendo hoje a cv. Bragantina a mais representativa nas lavouras capixabas. A pipericultura no Espirito Santo necessita urgente de estudos e pesquisas para continuar a ser destaque de produtividade, com tecnologias apropriadas para a região. Neste sentido a qualidade das plantas matrizes inicia-se com a produção de mudas de excelência. Apesar da experiência dos viveiristas da região em produzirem mudas por estaquia, as etapas deste processo devem ser muito bem inspecionadas para garantir o máximo de eficiência. O estudo teve como objetivo investigar o sistema de produção de mudas de pimenteira-do-reino e a qualidade dos substratos utilizados nos viveiros. Foi solicitado ao Ministério da Agricultura Pecuária e Abastecimento (MAPA) a localização de viveiros em conformidade com a legislação pertinente, e mediante as informações prestadas foram realizadas visitas técnicas a 11 viveiros, registradas por meio de um questionário. Coletaram-se amostras dos substratos utilizados na produção de mudas. As respostas dos questionários foram tabeladas e transformadas em gráficos de frequência relativa para melhor contextualização da situação. Os mesmos substratos foram utilizados para montar um experimento fatorial 11 (substratos) x 2 (presença e ausência de ácido-3-indolbutírico (AIB), visando avaliar o enraizamento de estacas de pimenteira-do-reino cv. Bragantina, que foi conduzido em blocos ao acaso com quatro repetições de 16 estacas, na casa de vegetação localizada no Centro Universitário Norte do Espírito Santo, no município de São Mateus-ES. Constatou-se que não existe uniformidade na produção de mudas, na infraestrutura dos viveiros e nas técnicas utilizadas. As diferenças estão relacionadas à origem das plantas matrizes, ao material propagativo, e ao manejo durante o crescimento das mudas, ficando confirmada pelas análises, diferenças na composição química, física e biológica dos substratos, influenciadas, principalmente, pela diversidade da fonte de matéria orgânica e a utilização ou não de corretivos e adubações. Conclui-se que, apesar de todos os viveiros serem registrados no Registro Nacional de Sementes e Mudas (RENASEM) e estarem em conformidade com as exigências legais em vigência, ainda é necessário pesquisar e estudar as divergências para que a produção de mudas de pimenteira-do-reino possa alcançar a excelência nos resultados. A qualidade do enraizamento de estacas de pimenteira-do-reino nos substratos utilizados pelos viveiristas, foi analisada estatisticamente por testes de médias (Tukey ou Scott-Knott em nível de 5% de probabilidade), e constatou-se aumento significativo na porcentagem de enraizamento com a aplicação de ácido indolbutírico, e diferença significativa na qualidade do enraizamento entre os substratos

Full textIn the Brazilian scenario Strawberry culture is presented as an alternative crop , because it fits in regions of temperate , subtropical and tropical climate, and is an important production chain , from an economic and social perspective. The cultivation in protected environment emerged as an ally in creating a more favorable microclimate production, controlling climate variations at different locations and times of planting. Allied to the environment, fertilization via biofertilizer doses, may contribute to nutrition, establishment and growth of strawberry production. In this approach, the biofertilizer has been presented as an alternative that has been adopted in agriculture as an option of reusing waste without proper destination in the properties. In this context, we conducted a job in the Experimental Farm of the University of International Integration Lusophone African- Brazilian ( UNILAB ), located at Sitio PiroÃs, municipality of RedenÃÃo, CearÃ, in the Massif Baturite, from September 2013 to January 2014, with the objective of evaluating the effects of different cultivation environments and doses of biofertilizer on growth, nutrition, yield and quality of strawberry Oso Grande, and generate technology to be diffused over the handling of the strawberry crop conditions edaphoclimatic of the Massif Baturite region. The experiment was conducted in randomized complete block design with split plot design with four replications. The plots consisted of two cropping systems (under greenhouse and field craft) and subplots consisted of five doses of liquid biofertilizer equivalent to 0, 400, 800, 1200, 1600 mL plant - 1 week - 1. Climatic characteristics of the site, nutritional soil and leaf tissue as a function of different doses of biofertilizer, and still vegetative characteristics of productivity and quality were analyzed. The strawberry crop in greenhouse conditions handmade showed highest yield (10.734 kg ha - 1), in relation to cultivation in open field (9.629 kg ha - 1). The biofertilizer can be used as a source of nutrients in the cultivation of strawberries in open field conditions, cultivar Oso Grande, meeting the demands of culture. The nutrient content in soil and leaves showed significant increases with the application of doses of biofertilizer, contributing to the health of plants. The vegetative characteristics of plants and post- harvest fruit grown in open field conditions showed higher values compared to cultivation in greenhouse condition artisanal, indicating that the temperature and luminosity affects such characteristics. The strawberry crop at conditions of the Massif Baturite - Cearà in months with milder temperatures get higher productivity.
No cenÃrio brasileiro a cultura do Morangueiro apresenta-se como uma alternativa de cultivo, pois se adapta em regiÃes de clima temperado, subtropical e tropical, e representa uma importante cadeia produtiva, do ponto de vista econÃmico e social. O cultivo em ambiente protegido desponta como um aliado na criaÃÃo de um microclima mais favorÃvel a produÃÃo, controlando variaÃÃes climÃticas em diferentes locais e Ãpocas de plantio. Aliado ao ambiente, a adubaÃÃo via doses de biofertilizante, pode contribuir para a nutriÃÃo, estabelecimento e incremento produtivo do morangueiro. Nesse enfoque, o biofertilizante tem se apresentado como uma alternativa que vem sendo adotada na agricultura como opÃÃo de reaproveitamento de resÃduos sem destinaÃÃo adequada nas propriedades. Neste contexto, foi conduzido um trabalho na Ãrea da Fazenda Experimental da Universidade da IntegraÃÃo Internacional da Lusofonia Afro-Brasileira (UNILAB), localizada no SÃtio PiroÃs, municÃpio de RedenÃÃo, CearÃ, no MaciÃo de BaturitÃ, no perÃodo de setembro de 2013 a janeiro de 2014, com o objetivo de avaliar os efeitos de diferentes ambientes de cultivo e de doses de biofertilizante no crescimento, nutriÃÃo, produtividade e qualidade do morangueiro Oso Grande, e gerar tecnologia, para ser difundida, sobre o manejo do cultivo do morangueiro nas condiÃÃes edafoclimÃticas da regiÃo do MaciÃo de BaturitÃ. O experimento foi conduzido no delineamento em blocos ao acaso no esquema de parcelas subdivididas, com quatro repetiÃÃes. As parcelas foram constituÃdas de dois sistemas de cultivo (sob telado artesanal e a campo aberto) e as subparcelas foram constituÃdas por cinco doses de biofertilizante lÃquido equivalentes a 0, 400, 800, 1200, 1600 mL planta-1 semana-1. Foram analisadas as caracterÃsticas climÃticas do local, nutricionais do solo e do tecido foliar em funÃÃo das doses diferenciadas de biofertilizante, vegetativas e ainda caracterÃsticas de produtividade e qualidade. O cultivo do morangueiro em condiÃÃes de telado artesanal apresentou maior produtividade (10.734 kg ha-1), em relaÃÃo ao cultivo em campo aberto (9.629 kg ha-1). O Biofertilizante pode ser utilizado como fonte de nutrientes no cultivo do morango em condiÃÃes de campo aberto, cultivar Oso Grande, atendendo as exigÃncias da cultura. Os teores de nutrientes no solo e nas folhas apresentaram incrementos significativos com a aplicaÃÃo de doses de biofertilizante, contribuindo para a sanidade das plantas. As caracterÃsticas vegetativas das plantas e de pÃs-colheita dos frutos cultivados em condiÃÃes de campo aberto apresentaram maiores valores em relaÃÃo ao cultivo em condiÃÃo de telado artesanal, indicando que a temperatura e a luminosidade afeta tais caracterÃsticas. O cultivo do morangueiro nas condiÃÃes edafoclimÃticas do MaciÃo de BaturitÃ-Cearà em meses com temperaturas mais amenas, obterà maior produtividade.

Resumo: O objetivo do trabalho foi avaliar a relação entre as fases do crescimento da cana-de-açúcar com as formas de curvas do perfil temporal do Índice de Vegetação por Diferença Normalizada - NDVI, obtidas a partir do sensor remoto orbital MODerate-resolution Imaging Spectroradiometer - MODIS, na região de estudo. A avaliação desta relação é realizada utilizando-se técnicas de sensoriamento remoto para a geração do perfil temporal do NDVI, ao longo do ciclo de desenvolvimento fenológico da cana-soca, nas maturações Precoce, Média e Tardia. Os talhões de cana-soca analisados foram agrupados de acordo com a variedade, solo, data de plantio e corte, e contigüidade. A visualização gráfica das formas de curvas analisadas é realizada através de aplicativo, desenvolvido neste trabalho na linguagem de programação Java, e do sistema gerenciador de banco de dados PostgreSQL. O aplicativo realiza a filtragem de ruídos presentes nas imagens, composição na resolução temporal de 8 dias, através dos dados da banda de controle de qualidade do produto MOD09Q1, realiza a eliminação de valores discrepantes ao longo do perfil temporal do NDVI para a safra analisada, corrige as influências dos períodos de corte e rebrota da cana-soca, e propicia a suavização da forma de curva através do filtro Savitzky-Golay. Três janelas temporais de monitoramento da cultura são apresentadas neste trabalho. Cada janela temporal é determinada em função do tipo de maturação da cultura, do coeficiente de cultura (Kc) ao longo do ciclo fenológico da cana-soca e do comportamento na evolução do perfil temporal do NDVI. Concluiu-se que na região de estudo, diferentes maturações são caracterizadas por diferentes formas de curvas do perfil temporal do NDVI
Abstract: The objective of the work was to evaluate the relationship among the phases of the growth of the sugarcane with the forms of curves of the Normalized Difference Vegetation Index - NDVI temporal profile, obtained from remote sensor orbital MODerate-resolution Imaging Spectroradiometer - MODIS, in the study area. The evaluation of this relationship is accomplished by using of the techniques of remote sensing to generate the NDVI profile, along the phenological development phase of stubble-cane, in the Carly, Medium and Late maturations. The fields of stubble-cane analyzed were contained in agreement with the variety, soil, planting date and cut, and proximity. The graphic visualization of curves shape analyzed is accomplished through application, developed in this work in the Java programming language, and of the PostgreSQL system database manager. The application accomplishes the filtering of present noises in the images, composition in the temporal resolution of 8 days, through the data of the band of quality control of the MOD09Q1 product, accomplishes the elimination of outliers along the NDVI temporal profile for the culture analyzed, corrects the influences of the cut periods and regrowth of the stubble-cane, and propitiates the smoothing in the curve shape through the filter Savitzky-Golay. Three temporal windows of culture monitoring are presented in this work. Each temporal window is determined in function of the type of crop maturation, of the culture coefficient (Kc) along the phenological development phase of stubble-cane and of the behavior in the evolution of the NDVI profile. It concluded that in the study area, different maturations are characterized by different forms of NDVI profile curves

Climate change, increased demand for locally sourced ingredients, and elevated pressure for environmentally responsible practices will make meeting the growing demand for food difficult for farmers to achieve over the next few decades. Similar to many other industries, implementation of advanced technology may be necessary to keep up with agricultural demand. Plant growth regulators are one such technology which when applied to plants can cause them to remain short, decreasing the chance of blowing over during windstorms. However, chapter one of this dissertation concluded that risks of plant injury also exist when applying plant growth regulator on malting barley (for brewing or distilling). Application should be restricted to fields with greater risk of wind damage (e.g. taller barley) and made only after the barley crop begins spring growth and a decrease in air temperature is not forecasted in the week following application. Chapter two compared eight spectral vegetation indices across three satellites with different image resolution for their ability to estimate cover crop biomass. Cover crops protect groundwater and surface water quality, but only when adequate growth is achieved. Satellite imagery was able to estimate multi-species cover crop biomass more accurately than field-based sensors, although the most accurate vegetation index was dependent upon which satellite was being tested. Chapter three investigated the potential of Arabidopsis thaliana ipk1-, a loss-of-function mutant which exhibits decreased growth at elevated phosphorus concentration, as in indicator of plant available phosphorus in soil. An indicator crop could help determine which areas of a field are likely to have increased crop yield if fertilized and which are not. The mutant tested could be useful as an indicator crop given its response to phosphorus concentration, warranting further research with other plant species more appropriate for field use.

Full textTiivistelmä Syväjäädytys mahdollistaa geenivarojen säilytyksen erittäin alhaisissa lämpötiloissa (<-150°C), siten että niiden elin- ja uusiutumiskyky säilyvät. Menetelmä soveltuu erityisesti sellaisten kasvimateriaalien pitkäaikaissäilytykseen, joita ei voida säilöä siementen avulla. Peruna (Solanum tuberosum L.) on yksi maailman tärkeimmistä ruokakasveista ja sen geenivaroja säilytetään lähes pelkästään vegetatiivisesti. Syväjäädytysmenetelmää käytetäänkin kasvavissa määrin perunan geenivarojen taltioimiseen geenipankeissa. Haasteena on kuitenkin syväjäädytyksen jälkeinen suuri vaihtelu elpymisprosenteissa eri genotyyppien välillä. Valon laatu on yksi tärkeimmistä kasvien kasvuun ja kehitykseen vaikuttavista tekijöistä, mutta sen vaikutusta syväjäädytyksen yhteydessä ei ole tutkittu. Väitöskirjassani tutkin kuuden erilaisen valonlaadun vaikutusta sekä syväjäädytystä edeltävän että sen jälkeisen kasvatuksen aikana viiden perunalajikkeen selviytymiseen. Lisäksi tutkin, miten erilaiset valo-olosuhteet vaikuttivat geenien ilmenemiseen elpyvissä perunan versonkärjissä. Tutkimukseni osoitti, että valon laatu vaikuttaa merkittävästi perunan versonkärkien kykyyn elpyä syväjäädytyksestä in vitro -olosuhteissa. Kun perunan versonkärkiä kasvatettiin sinisten LED-valojen alla ennen syväjäädytystä, niiden elävyysprosentit olivat korkeita, kun taas syväjäädytystä seuraava kasvatus sinipunaisten LED-valojen (90 % punaista, 10 % sinistä) alla kaksinkertaisti uusiutumisprosentit. Samanaikaisesti suurimmalle osalle lajikkeista punaisilla LED-valoilla oli epäsuotuisat vaikutukset selviytymiseen sekä syväjäädytystä edeltävän, että sitä seuraavan kasvatuksen aikana. Perunan kärkisilmujen geeniekspressioanalyysi osoitti, että syväjäädyttäminen aiheuttaa laajoja ja monitahoisia vaikutuksia kasvin geenien toiminnassa. Valon laatu vaikutti erityisesti stressi- ja puolustusgeenien ilmenemiseen. Tulokset viittaavat siihen että sinipunaisten LED-valojen uusiutumista edistävä vaikutus voi liittyä morfogeneesissä toimivien geenituotteiden runsauteen ja toisaalta stressi- ja puolustusgeenituotteiden määrän laskuun. Kaiken kaikkiaan tutkimukseni osoitti, että valon laatu on tärkeä ei-kryogeeninen tekijä, joka voi lisätä kasvien syväjäädytyksen tehokkuutta
