Повний текст джерелаIndustrial chicory, Cichorium intybus L. var. sativum, accumulates a wide array ofpotent specialized metabolites. These metabolites exhibit very diverse structures, activities and functions that are remarkable from a physiological standpoint, but also for their applications such as in human and animal health, agronomy and other diverse industries.This work focused on two specialized metabolites of C. intybus: an unusual phenolamide tetracoumaroyl-spermine (TetraSpm) and 3,5-isochlorogenic acid (diCQA). This research contributes to the biochemical and physiological characterization as well as the investigation of the evolutive history of the enzymes involved in the biosynthesis of these two hydroxycinnamic acid conjugates. We used computational analysis and molecular engineering approaches.We demonstrated the sequential action of the two CiSHTs (Spermine Hydroxycinnamoyl Transferases) in vivo in the biosynthetic pathway of TetraSpm. We investigated the influence of free polyamine availability and structural features on the catalytic activities of SHT proteins. Furthermore, we engineered a chimeric protein able to catalyze the production of TetraSpm in a single step.The study of diCQA metabolism in C. intybus involved the identification and preliminary characterization of target genes belonging to the GDSL-lipase like enzymatic family. Moreover, it emphasized the diversity of plant acyltransferases involved in specialized metabolism. The physiological roles and functions of TetraSpm and diCQA are still to be determined. However, the conservation of TetraSpm among the Asteraceae family suggests that it plays a significant role in their evolution, and the therapeutic properties of diCQA are of great interest in human health. Thus, deciphering these biosynthetic pathways is crucial for their reconstitution in more efficient systems via molecular engineering and consequently the valorization of these compounds
Bravo, Vergês Rodrigo Kamal. "Selección de variedades de radicchio (Cichorium intybus L.) para la zona central de Chile." Tesis, Universidad de Chile, 2013. http://repositorio.uchile.cl/handle/2250/147793.
Повний текст джерелаExisten en el mercado nacional variedades híbridas de radicchio (Cichorium intybus L.), de alto rendimiento y homogeneidad, su limitante es el alto costo de la semilla. La más importante es ‘Leonardo’, de semillas Bejo, que representa 90% del mercado, sin embargo, se cree que existen variedades de polinización abierta que podrían utilizarse como alternativa a los híbridos a un menor costo. Este estudio, buscó seleccionar variedades de polinización abierta con igual o mejor rendimiento exportable que ‘Leonardo’, con el fin de establecer bases de recomendación de cultivares en la zona central de Chile. Se evaluaron 11 variedades de radicchio, en un diseño experimental de bloques completos al azar con cinco repeticiones. El ensayo se realizó en 4 localidades de la zona central de Chile, durante la temporada 2007-2008. En cada localidad se evaluaron 3 fechas de siembra, la combinación localidad x fecha de siembra generó 12 ambientes. Se evaluó el rendimiento exportable, peso de la cabeza, porcentaje de plantas enfermas, emisión prematura de tallo floral y color exportable, se realizaron análisis combinado de varianza, de estabilidad, AMMI, SREG, PLS y componentes principales. El rendimiento exportable de las variedades fluctuó entre 23,34 t ha-1 (‘Leonardo’) y 6,84 t ha-1 (‘CH121’), y de los ambientes entre 25,89 y 8,18 t ha-1 . El análisis combinado de varianza del rendimiento exportable, mostró efecto significativo para GxA. El tipo de radicchio (Treviso o Chioggia) resultó ser la principal causa de interacción para rendimiento exportable. En términos de rendimiento exportable, ‘Ciro’ (Chioggia) podría considerarse como una buena alternativa económica a ‘Leonardo’ en el mega ambiente formado por las tres fechas de siembra de Polpaico, Santo Domingo y Lampa, mientras que ‘Tullio’ (Treviso) podría ser alternativa en las tres fechas de siembra de Padre Hurtado. ‘Ciro’ destacó no sólo porque rindió 18,7% menos que ‘Leonardo’ (P<0,05) sino porque también es más estable que ‘Leonardo’. ‘Tullio’ rindió 24% más que ‘Leonardo’ en las tres fechas de siembra de Padre Hurtado (P<0,05). La reducción del rendimiento exportable se debió principalmente a enfermedades.
In the Chilean national market there are hybrid varieties of radicchio (Cichorium intybus L.) with high yield and homogeneity, its limitation is the high cost of the seed. The most important is ‘Leonardo’, Bejo seed, which represents 90% of the market, however, it is believed that there are open-pollinated varieties that could be used as an alternative to hybrids at lower cost. This study sought to select open-pollinated varieties with equal or better exportable performance than ‘Leonardo’, in order to establish bases on the recommendation of cultivars for the central zone of Chile. Eleven varieties of radicchio were evaluated in a randomized complete block desing with five replications. The trial was conducted in four localities of central Chile, during the 2007-2008 seasons. At each site, 3 planting dates were evaluated. The combination of locality x transplant date generated 12 environments. Exportable yield, head mass, percentage of diseased plants, early flowering bolting and exportable color were evaluated. Combined analyzes of variance, stability, AMMI, SREG, PLS and principal components were made. The exportable yield of the varieties ranged from 23,34 t ha-1 (‘Leonardo’) to 6,84 t ha-1 (‘CH121’), and the environments ranged between 25,89 and 8,18 t ha-1 . The analysis of the exportable yield variance showed significant GxE effect. The type of radicchio (Treviso or Chioggia) was the main cause of interaction for exportable yield. In terms of exportable yield, ‘Ciro’ (Chioggia) could be considered as a good alternative to ‘Leonardo’ in the mega environment formed by the three planting dates of Polpaico, Santo Domingo and Lampa, while ‘Tullio’ (Treviso) could be an alternative in the three planting dates of Padre Hurtado. ‘Ciro’ yield 18,7% less than ‘Leonardo’ (P <0,05) but showed better stability than ‘Leonardo’ and ‘Tullio’ yield 24% more than ‘Leonardo’ in the three planting dates of Padre Hurtado (P <0,05). Exportable yield reduction is mainly due to diseases.

Повний текст джерелаENGLISH ABSTRACT: South Africa is one of the worlds leading producers of chicory (Cichorium intybus L.). Most of the chicory produced is used locally for the production of instant coffee. Witloof chicory, or Belgian endive, however, is a vegetable crop grown from the root of Cichorium intybus L. var. foliosum. This is done by placing the mature taproot in a controlled, dark environment after vernalization and supplying it with water and nutrients by means of hydroponics. Witloof chicory is new to the South African market and is only produced on a limited scale. Nonetheless, seeing that chicory is successfully grown on a large scale for the coffee industry it seemed reasonable to investigate the cultivation of this essentially unknown vegetable locally. The focus of this study was on the evaluation of new witloof production techniques during the second stage of witloof (chicon) cultivation, also called 'forcing'. To this end, locally grown witloof chicory roots were used in all trials. In order to establish the effects of several irrigation methods on lateral root formation and chicon quality, witloof chicory roots were forced using the conventional means of hydroponic irrigation as well as ebb-and-flood and aeroponic irrigation. Lateral root formation was significantly increased when either ebb-and-flood or aeroponic irrigation was applied compared to that obtained with the conventional method. This increase in lateral root formation was, however, to the detriment of chicon quality (QI), possibly as a result of competition for limited carbohydrate reserves. In an attempt to optimize the aeroponic irrigation method, roots were forced in non-vertical positions. Placing roots horizontally during forcing resulted in a significantly lower marketable chicon yield than where roots were placed vertically. The loss in yield was probably brought about by an increased fallout percentage rather than by a decrease in chicon production. Considering the pivotal role that sucrose plays in the development of the chicory head, sucrose was applied exogenously to the root before and/or during forcing. Dry matter chicon yield was negatively effected by exogenously applied sucrose. This could have been due to an increased incidence of fungal or bacterial infections or causative of roots absorbing less water resulting in the inability of the plant to utilize the applied sucrose during chicon development. Fungal and bacterial infections are known to have a detrimental effect on witloof chicory production. An environmentally friendly product for disease control, 'Desogerme SP®', was used to contain or reduce infection. Irrigation of roots with 'Desogerme SP®' containing nutrient solution increased chicon yield by 31%. From this study it became clear that some new production techniques applied had the potential of improving lateral root formation or quality during growth. However, the conventional way of irrigation remains the most effective compared to the other techniques applied, but could possibly be improved to some extent by incorporating 'Desogerme SP®' either as a pretreatment or in the nutrient solution. A breakthrough was made with the development of the quality index (QI). The ongoing limitation of statistically analyzing quality data of chicons sorted according to quality-classes was overcome by making use of this tool. Despite the fact that the index was developed specifically for use on witloof, it is has the potential of being applied to quality data of a wide variety of crops.
AFRIKAANSE OPSOMMING: Suid Afrika is een van die wêreld se grootste produsente van sigorei (Cichorium intybus L.). Die meeste plaaslik geproduseerde sigorei word vir die produksie van kitskoffie benut. Witloofsigorei, of Belgiese "endive", is egter 'n groentegewas wat vanaf die wortel van Cichorium intybus L. var. foliosum gekweek word. Dit word gedoen deur die volwasse penwortel na vemalisasie in 'n gekontroleerde, donker omgewing te plaas en met 'n hidrokultuurstelsel van water en voedingselemente te voorsien. Witloof is nuut op die Suid Afrikanse mark en word net op beperkte skaal geproduseer. Aangesien sigorei suksesvolop groot skaal vir die koffieindustrie geproduseer word, blyk dit logies om die moontlikhede te ondersoek om hierdie relatief onbekende groente plaaslik te kweek. Die fokus van hierdie studie was gerig op die evaluasie van nuwe produksietegnieke gedurende die tweede fase van witloofproduksie, wat ook as forsering bekend is. Plaaslik gekweekte witloof sigoreiwortels is vir alle eksperimente gebruik. Die invloed van 'n verskeidenheid besproeiingsmetodes is op sywortelproduksie en witloof krop-kwaliteit ondersoek. Witloofwortels is geforseer deur van 'n konvensionele hidrokultuur-stelsel gebruik te maak wat met 'n ebb-en-vloed en 'n lugsproei sisteem vergelyk is. Sywortel-produksie was betekenisvol hoër waar ebb-en-vloed of lugsproei sisteme toegepas is. Hierdie verbetering in sywortel-ontwikkeling was egter tot nadeel van krop-kwaliteit, vermoedelik as gevolg van die allokasie van koolhidrate na sywortels, eerder as na die groeipunt. In 'n poging om die lugsproei besproeiingsmetode te verbeter en om swamsiektes te verminder, is wortels in nie-vertikale posisies geforseer. Wortels wat gedurende forsering horisontaal ingetafel was, het 'n betekenisvol laer opbrengs van bemarkbare kroppe getoon as wortels wat vertikaal geplaas was. Die verlies aan opbrengs kon toegeskryf word aan 'n verhoging van afval, aangesien geen betekenisvolle afname in vars krop-gewig gevind is nie. Aangesien sukrose 'n belangrike rol in die ontwikkeling van die witloofkrop speel, is sukrose voor en tydens forsering aan die wortels toegedien. Droë materiaal krop-opbrengs is negatief deur die toediening van sukrose beïnvloed. Dit kon moontlik as gevolg van 'n verhoogde voorkoms van swam- of bakteriese infeksies gewees het of 'n aanduiding wees dat behandelde wortels minder water geabsorbeer het en die toegediende sukrose nie kon gebruik gedurende krop-ontwikkeling me. Swam- en bakteriese infeksies is bekend vir hul negatiewe uitwerking op witloofproduksie. 'n Omgewingsvriendelike middel, 'Desogerme SP®' is gebruik om siektes te beheer ofte verminder. Wortels wat met 'n 'Desogerme SP®' bevattende voedingsoplossing besproei is, het 'n 31% verhoging in krop-opbrengs getoon. Uit data wat gedurende hierdie studie ingesamel is, blyk dit duidelik dat sommige van die nuwe produksietegnieke wel die potensiaal het om sekere planteienskappe te verbeter. In geheel gesien bly die konvensionele metode van besproeiing die mees effektiewe, wanneer dit vergelyk word met die ander wat getoets is. Die konvensionele metode kan moontlik verbeter word as 'Desogerme SP®' as 'n vooraf-behandeling of as deel van die voedingsoplossing geïnkorporeer word. 'n Deurbraak is met die ontwikkeling van 'n kwaliteitsindeks (QI) gemaak. Ernstige beperkings word met statistiese ontledings van kwaliteitsdata ervaar waar kroppe volgens kwaliteitskiasse gesorteer word. Hierdie probleme is met behulp van die QI oorkom. Ongeag die feit dat die indeks spesifiek vir gebruik by witloof ontwikkel is, het dit die potensiaal om toepassing te vind by 'n wye reeks landboukundige produkte.

Повний текст джерелаThe bacterial flora isolated from chicory rot during forcing was characterized. Typical well-known symptoms as well as atypical symptoms encountered during present studies, were investigated on roots and chicons. Isolates were mainly related to Erwinia carotovora subsp. Atroseptica. They formed an homogeneous group from a biochemical point of view and an heterogeneous one with respect to their serological characteristics. Methods for assessing pathogenicity of the isolated bacterial strains were tested on whole plants during forcing and also on isolated organs in order to deter m ne the effect of the physiological stage of plants, of inoculum level and of modes of inoculation. The life cycle of bacteria was investigated by studying the penetration in plant tissues of spontaneous and artificial E. C. A. Inocula; the inoculation of strains during the vegetative growth of C. Intybus did not lead to expression of bacteriosis. Inoculations during forcing produced much variable results which were especially dependent on temperature. Observations of bacteriosis in most of the experimental control lots suggest that Erwinia was potentially present in all roots during forcing: this bacteriosis is an opportunistic disease. The use of a chemical (copper sulphate in the form of Bordeaux mixture) able to modify the bacterial flora both qualitatively and quantitatively, indicated that E. C. A. Could possibly penetrate into plants during vegetative growth. It also demonstrated the presence of bacterial infection in leaf residues (left after harvesting of roots) which accounts for subsequent rot during forcing. The study of the influence of some agro-climatic factors on disease expression showed that previous growing conditions of roots (nitrogen fertilization in the field) were positively correlated to chicon mortality, and that the disease expression was highly dependent on the conditions of root storage and forcing temperature

Повний текст джерелаThe development of an ovule and anther clearing technique allowed us to observe and establish the chronology of the different sexual reproduction stages in witloof chicory: micro and megaga metogenesis male cells migration to pollen tube and embryo sac, double fertilization embryogenesis. The 2 sperm cells conection in the pollen tube and also the association between the vegetative nucleus and the 2 sperm cells on entering the embryo sac were demonstrated. This male germ unit appeared to be dissociated in the micropylar area of the embryo sac. The evolvement in the form of sperm cells during migration was observed. The hypothesis of structure regulation by a microtubular network was put forward after investigation of colchicine action on sperm cells. The development of in vitro germination of pollen and zygotic embryos culture allowed us to study in vitro fertilization. Cytological analysis of embryo sacs evidenced the occurrence of in vitro fertilization 3 plants could thus be regenerated. Haploidization was investigated by different ways: in vitro gynogenesis by means of non fertilized ovules culture, in situ gynogenesis using irradiated pollen and in situ androgenesis by ovule irradiation. Cytological observation of the embryo sac allowed us to analyse how these various treatments act and from which cells the gynogenetic embryos derive. The potentialities of each haploidization technique are discussed

Повний текст джерелаGenerally under the control of one locus, the S-locus, self-incompatibility (SI) is one of the most important strategies to prevent selfing in hermaphrodite plants. Determinants involved in the SI reaction have been identified in some Angiosperm families. In the Asteraceae family, determinants of SI are still unknown. Chicory (Cichorium intybus L., Asteraceae) is a sporophytic SI species. To identify determinants of chicory SI, a positional cloning strategy has been implemented.The chicory S-locus has been assigned to one end of linkage group 2. A high density map have been obtained from a marker assisted BSA (Bulk Segregant Analysis) approach: 5 AFLP markers were obtained, including one co-segregating with the S-locus. From a large population (n = 2.824), 2 consensus high-resolution map of the S-locus region were produced. Due to a heterochiasmy phenomenon, the S-locus was positioned in an interval of 0,6 cM or 1,24 cM considering female or male meiosis, respectively.Two BAC libraries of chicory were produced in collaboration with the CNRGV. They allowed us to start chromosome walking and to turn it toward the S-locus. Moreover, 6 BAC clones, corresponding to 546 kb, were sequenced and analyzed. A ratio of 0,5 Mb/cM for male meiosis and 2,2~Mb/cM for female meiosis were obtained. Repeated element composition and coding part of the sequences were studied (libraries of Cichorium sp. EST and Arabidopsis thaliana and Vitis vinifera peptides). A certain degree of conservation of microsynteny was observed between these genes and their homologues in five Dicotyledon species

Повний текст джерелаSomatic embryogenesis (SE) Is an asexual re-production pathway in which somatic cells form embryos in a process that resembles zygotic embryogenesis. ln chicory a genetic variability in the capacity of somatic embryo formation was found, and two contrasting genotypes were selected K59, embryogenic. and K28, hardly embryogenic were selected for obtain a F1' progeny. Vanabllity for somatic embryo formation was exploited to identify chromosomal regions (QTL) and candidate genes implicated in ES. After 7 days of culture of root explants under SE-inducing conditions and 30 days of development the number of plantlets (PL) and shoot-like structures (SH) obtained were counted. The traits PL and SH showed continuous and normal distributions after log10 transformation, and heritabilities superior to 63%. A genetic map for the K28*K59 progenies was built for a QTL analysis related to ES. Six QTL were detected for both PL and SH that together explained more than 23% and 44% of the phenotypic variation for these traits. respectively. Amongst the 63 mapped candidate genes, 16 co-Iocalised with QTL for PL and SH. ln view of their implication in the maintenance of the undifferentiated state of the stem ceIls in shoot apical meristems. the co-localisation of genes homologous to SHOOT MERISTEMLESS (STM) and ARGONAUTE (AGO) in Arabidopsis wlth QTL6 and QTL2. respectively. is a particular interesting result. With the detection of QTL for SE. the results of this study have for the first time revealed elements in the genetic control of SE in chicory

Повний текст джерелаChicory is grown in Brazil mainly by small landowners, which usually product other horticultural crops. Chicory is mainly used for human feeding, but it has potential for inuin production and also potential for animal feeding. This study aimed at evaluating the effect of applying percentages of crop evapotranspiration by irrigation over vegetable production of \"Folha Larga\" chicory cultivar grown in greenhouse. Two experiments were performed in the of completely randomized design under five percentages of crop evapotranspiration (ETc): 60, 80, 100, 140% applied by drip irrigation. The experimental area was constituted of 45 plots of 1.3 m2 each, each plot had a solenoid valve to control the duration of the irrigation, totaling nine plots for each treatment. Soil humidity was monitored through three TDR probes (Time Domain Reflectometry), installed at 0.05, 0.30, and 0.50 m depth. The meteorological conditions were monitored using a meteorological station, which recorded measures of relative air humidity, air temperature, solar radiation and wind speed, taking measures at each second and registering the data at each 15 minutes. From meteorologic data, the reference evapotranspiration was estimated by the Penman-Monteith FAO-56 method, and the crop evapotranspiration, using an average crop coefficient equal to 0.76. Two consecutive experiments were performed, applying the percentages of ETc during all the chicory growth period. The measured and analyzed variables were: plant height (cm), number of leaves per plant, plant fresh mass (g), fresh mass by leaf (g leaf-1), plant dry mass (g), plant humidity (%), leaf area (cm2), leaf length (cm) and leaf width (cm). The data of each treatment was used to perform the joint analysis of variation and average test or regression analysis, resulting that only for the variables of leaves fresh and dry weight it was possible to adjust equations to represent the mean values of both experiments. It was observed that the plant fresh weight presented itself directly proportional to increments of percentages of evapotranspiration, being that the treatment of 140% of ETc was the treatment that resulted higher production of plant fresh weight, approximately 31.6% higher than the production obtained from treatment of 60% of evapotranspiration. For the data of plant dry mass, it was observed that the percentage of 111.1% of evapotranspiration was the one that obtained higher values of plant dry weight, being 29.3% higher than the production of plant dry mass obtained with the treatment of 60% of ETc and 9.35% higher than the one obtained with the treatment of 140% of evapotranspiration. From the data of leaf area, length and width of the first experiment, was possible to adjust four models with residuals with normal tendency and homocedastic, which were tested by the Bland- Altman method with the data of leaf area, length and width of the second experiment.

Повний текст джерелаSecondary metabolism corresponds to a class of compounds allowing plants to survive in their environment. Among these molecules, polyphenols display widely studied antioxidant properties. The aim of this work was to study the genetic control of biosynthesis of polyphenols detected in chicory leaf tissue, using a QTL (Quantitative Trait Loci) analysis approach based on a F1’ progeny. First, a high-throughput protocol was set up and permit us to identify caftaric acid, chlorogenic acid and chicoric acid. In this context, 201 individuals from the F1’ progeny were phenotyped for caftaric, chlorogenic and chicoric acid amounts (respectively ACAFT, ACHLO, ACHIC), the total amount for these three molecules (ATOT), the radical scavenging ability (AAR), the ratio between the caftaric acid or chlorogenic acid and the entire phenolic acids detected (PCAFT and PCHLO, respectively). A specific genetic map was established from a previous map already published. Using SSR, AFLP, SSCP, HRM polymorphism, 142 markers covered the nine linkage groups of this map and among them, 16 candidate genes. Altogether, 20 QTLs were then detected: 1 for ACAFT (R² = 16,4%), 3 for ACHLO (R² = 50%), 2 for ACHIC (R² = 13,9%), 4 for AAR (R² = 31%) et 5 for PACFT (R² = 44%) and PCHLO (R² = 61%). Eight QTLs co-localised with 7 encoding-enzymes genes involved in the phenylpropanoid pathway. This study is the first step toward understanding the genetic control of the main phenolic acids in chicory leaves, particularly caftaric and chicoric acid, only synthesised in few species

Повний текст джерелаIn order to provide a useful reference for morphological studies on flower and seed development in Cichorium intybus, the normal development for these two organs was histologically characterised. With reference to the morphological events during normal flower development, we have shown that nuclear male sterility type "Edith" is associated with disturbances in the tapetum and middle layer cells as well as degeneration of microspores after the formation of meiotic tetrads. Histological resemblance with some mutants in Arabidopsis thaliana and in rice helped for selection of candidate genes for molecular analysis of this male sterility. Moreover, the cytoplasmic male sterility named "524" which was created by fusion of protoplasts from sunflower male sterile and from fertile chicory was also histologically characterised. During flower development in the male sterile “524” degeneration of pollen grains occurs at the first pollen mitosis, so that at anthesis, the pollen grains are empty; the anther locules are unopened and shrivelled and no lignified secondary thickenings are observed in endothecium. Moreover, morphological characterisation of flower development in plants carrying the cytoplasm “524” led us to demonstrate the existence of a mechanism of fertility restoration for which heredity needs to be investigated. For the achene and seed development, the timing of events and morphological and physiological characterisation of developmental stages revealed genetic variability in the duration of achene and seed development in chicory. The reference established for achene and zygotic embryo development will help more particularly analysing expression of genes which have been previously shown to be involved in the somatic embryogenesis process in chicory

Повний текст джерелаLe clonage du gène ciALS nous a fourni la séquence codante d'un domaine implique dans la fixation des herbicides chez la plante sensible. La mutation de l'ALS chez le variant r1ok a diminue la sensibilité de l'enzyme au rétrocontrôle exerce par la leucine et la valine respectivement d'un facteur 10 et 3. Le doublement des teneurs en valine et leucine chez ces plantes indique que l'ALS constitue un point de contrôle de la voie de biosynthèse de la valine, alors que la synthèse de leucine présente sans doute en plus un deuxième point de contrôle situe en aval de l'ALS dans la voie de biosynthèse des acides amines branches. L'altération de la sensibilité a la régulation allostérique de l'ALS par ces acides amines ne confère pas pour autant a la plante une résistance vis-à-vis d'apports exogènes de valine et de leucine

Повний текст джерелаMarketing possibilities for fresh-cut endive are limited by the rapid red discoloration of the leaves after cutting. This work proposes an alternative approach to prolong the shelf life of fresh-cut endive by inhibiting or delaying the red discoloration of pieces: the application of a heat shock at 46°C for 120 sec. The effect of heat shock on the activity of enzymes involved in the process of enzymatic browning and the accumulation of phenolic compounds were analyzed. The expression of genes involved PAL1, PAL2, PPO and Hsp90 was performed by following the accumulation of mRNA by real-time quantitative PCR. This work has shown that heat shock induces overexpression of Hsp90 and inhibits the activity of PAL, PPO, the accumulation of phenolic compounds and gene expression of PAL1 which consequently inhibition of discoloration for 8 days at 4°C. The controlled atmosphere (4%O2 + 5%CO2) is not sufficient to inhibit the red discoloration. The application of inhibitors of synthesis (AVG) and action of ethylene (1-MCP) has shown that ethylene is not involved in the inhibition of the synthesis of PAL in response to heat shock

Повний текст джерелаResumo: O sistema de consorciação é uma tecnologia muito utilizada na produção de hortaliças, e que influencia profundamente a produtividade das culturas, além de gerar inúmeras vantagens fitotécnicas quando manejado adequadamente; tornando-se necessários maiores estudos sobre época de estabelecimento dos consórcios, uma vez que esta afeta o período de convivência entre as espécies com reflexo nas produtividades. O objetivo foi avaliar e quantificar, por meio de índices agronômicos e ecológicos, a interação entre couve e almeirão em cultivos consorciados, distintos quanto à época de transplante do almeirão em relação à couve. Foi realizado um experimento em campo, em Jaboticabal, SP, Brasil, no período de maio a novembro de 2018. O delineamento utilizado foi de blocos casualizados, com 9 tratamentos, em esquema fatorial 2 x 4 + 1, com quatro repetições. Os fatores avaliados foram sistema de cultivo (consórcio e monocultura) e épocas de transplante do almeirão (0, 14, 28 e 42 dias após o transplante (DAT) em relação à couve, e a monocultura da couve. A produtividade da couve ‘HS-20’ em consórcio com almeirão ‘Folha Larga’ aumentou com o atraso de transplante do almeirão. A produtividade total e por colheita do almeirão não foi influenciada pela época de transplante. Consórcio de couve e almeirão proporciona maior eficiência no uso da área que suas monoculturas, e atingiu o valor máximo quanto o transplante ocorreu aos 42 dias após o transplante da couve.

Abstract: The intercropping system is a technology very used in the production of vegetable, which deeply influences crop productivity, besides generating numerous phytotechnical advantages when properly managed; further studies of the intercropping establishment times are needs, since it affects the coexistence period among the species, with a reflection on the productivities .The experiment were carried out under field condition in Jaboticabal, SP, Brazil in the period of May to November of 2018. in order to evaluating and quantifying by means of agronomic and ecological indices, the interaction of the species of collard green and chicory in intercropping, different regarding the time of transplanting of chicory relative to collard green. The experimental design was a randomized complete block with 9 treatments, in a 2 x 4 + 1 factorial scheme, with four replications. The factors evaluated were the cultivation system (intercropping and monoculture) and chicory transplant times (0, 14, 28 and 42 days after transplanting (DAT) relative to collard green and one monoculture of collard green. The yield of collard green 'HS-20’ in intercropping with chicory 'Folha Larga' increased with the delayed transplantation time of the chicory. The total yield and yield per harvest of the chicory was not influenced by the time of transplantation. The collard green and chicory in intercropping provides greater efficiency in the use of the area than their monocultures, and reached the maximum value whe...

Повний текст джерелаL'étude de l'expression des produits de ces gènes au cours de l'embryogenèse somatique de génotypes embryogène et non embryogène ainsi que lors de l'embryogenèse zygotique a été réalisée selon deux approches. Une analyse de la variation des niveaux. De transcrits a été réalisée par RT-PCR en temps réel. Parallèlement, l'accumulation de protéines a été suivie après obtention et purification d'anticorps polyclonaux dirigés contre le domaine kinase de CiSERK1. Les résultats indiquent que l'expression des gènes identifiés chez la chicorée n'est pas induite au cours des phases précoces de l'embryogenèse somatique. Le gène CiSERK2 ne présente pas de variation de son profil d'expression quel que soit le type d'embryogenèse. Le niveau de transcrits de CiSERK1 diminue au cours de la première demi-journée de culture en conditions embryogènes indépendamment du génotype. Au cours de l'embryogenèse zygotique, le niveau de transcrits de CiSERK1 augmente au stade cotylédonaire. L'approche immunologique a permis de détecter plusieurs protéines au cours de l'induction de l'embryogenèse somatique dont 2 (75 kDa et 62 kDa) sont accumulées de façon corrélée à des états cellulaires caractéristiques de l'induction de l'embryogenèse somatique. Au cours de l'embryogenèse zygotique, plusieurs protéines ont été détectées. Dont une de 62 kDa qui s'accumule au cours du développement de l'embryon.
