Abstract:
L'influence de la vigueur et du systeme de conduite de la vigne sur sa structure geometrique et son microclimat lumineux est etudiee. Une gamme de variation de structure et de microclimat a ete cree en combinant trois niveaux de vigueur et quatre systemes de conduite faisant intervenir la division de la vegetation et le port des rameaux. La structure geometrique est decrite a l'aide d'indices de structure couramment utilises en viticulture, des distributions spatiales et angulaires de surface foliaire et enfin des images virtuelles de souches de vignes reelles. Ces images de synthese sont obtenues a partir des donnees de digitalisation 3d des vignes qui permet de determiner les coordonnees spatiales et l'orientation de tous les organes aeriens de la plante. Le microclimat lumineux est simule par deux approches. La premiere approche utilise un modele de transferts radiatifs de type milieu diffusant. L'interception du rayonnement et sa distribution a l'interieur de la vegetation sont calcules et les resultats sont valides par des mesures au vignoble. Dans la seconde approche, le microclimat lumineux est simule a l'aide de maquettes informatiques en utilisant des images de synthese des vignes digitalisees. Cette approche a permis de calculer l'interception du rayonnement direct, la surface foliaire eclairee et la quantite de rayonnement parvenant au milieu de la zone des grappes. Les parametres radiatifs et les indices de structure obtenus a partir des images de synthese des vignes sont mis en relation avec quelques caracteristiques de la qualite de la vendange.

Abstract:
Des analyses de feuilles (sites de synthèse) et de baies (sites d'accumulation) ont été faites à quatre stades du développement des baies. Les résultats obtenus mettent en évidence les différences de composition qui existent, à chaque époque, entre les feuilles et les baies et entre les différentes parties de la baie (péricarpes, pellicules, moûts et pépins). Ils montrent aussi l'influence des conditions externes. A maturité des raisins, ce sont les pellicules et les péricarpes qui, par rapport à la matière sèche, sont plus riches en acides aminés libres, puis les pépins et les feuilles. L'acide glutamique, la glutamine et l'acide aspartique prédominent dans les feuilles, la proline et l'arginine dans les péricarpes, les pellicules, les moûts et les pépins.

Abstract:
Viognier (Vitis vinifera L.) grapes were grown in Northern Virginia for three seasons using three different training systems in a randomized complete block design consisting of Vertical Shoot Positioned (VSP), Smart Dyson (SD), and Geneva Double Curtain (GDC), and evaluated for the effects on grape and wine glycosides and volatile compounds. Fruit was harvested at the same Brix each season, and differences in berry weights were not observed. VSP-trained vines had the lowest crop load and lowest light levels in the fruit zone. Seventeen volatile compounds were analyzed using headspace solid-phase microextraction, GC-MS. Fruit showed differences in linalool, á-terpineol, â-damascenone, and n-hexanol concentrations among the training systems. Wines showed differences in both grape-derived and fermentation-derived volatiles. SD had the highest concentration for most of the free volatiles quantified in both the juice and wine. VSP had lower phenol-free wine glycosides all three seasons and lower phenol-free juice glycosides one season. Triangle difference sensory testing demonstrated differences between GDC and SD in wine aroma and flavor, and differences between VSP and SD in flavor, for two of three seasons.

Abstract:
The geographic traceability of food products through the use of chemical markers is an important challenge to ensure quality and authenticity of food. In recent years, the behaviour of Rare Earth Elements (REE) has been identified as possible tool for food geographical identification based on their known capability of tracing pedo-genetic and petro-genetic processes. In this thesis, the behaviour of REE in the Soil/Vitis vinifera L. system has been explored using a geochemical approach. The goal is to understand if the normalized pattern of REE (REE*) can be a useful tool to trace the geographical origin of food. REE may be accumulated in plants keeping their distribution in passing from soil to leaves or fruits. However, the mechanism of soil/plant REE transfer is poorly known, even if leaves may incorporate metals leached from atmospheric dust particles in particular environmental conditions. We focused on plants grown in both greenhouse and field using REE enriched and non-enriched substrates wondering if REE soil enrichments influence the growth of Vitis vinifera L. and the REE accumulation in plant organs testing the use of REE* as discriminator of small amounts of REE in the soil. We, also, have evaluated the role of xylem-sap in the transfer of REE transfer and the possible physiological impact in Vitis vinifera L. We found that the stress generated by REE enriched soil does not influence neither the plant mass nor the REE accumulation in leaves and demonstrated that the REE* in plant organs traces enriched soil substrates discriminating plants from different soils of growth. This work allows to propose that REE* as potential marker for identifying the substrate where Vitis vinifera L. grows. This work yields, also, important consequences from environmental perspective: since the REE amount in the substrates does not influence the amount accumulated in leaves REE polluted soils should not influence the amount of REE found in Vitis vinifera L food-products. Finally, discrimination of substrate enrichments suggests that REE* is a potential tool for quality and safety of other ecosystems. Our experimental investigation improves our knowledge on REE uptake in soil-Vitis vinifera L. system, highlighting the potential use of REE as biogeochemical tracers of environmental conditions.

Abstract:
Pour contribuer a resoudre le probleme du manque d'acidite de certains vins, nous avons etudie, en culture hydroponique, l'influence de differents equilibres k-ca sur la nutrition cationique et la qualite des mouts et des vins de negrette. Dans un premier essai, une serie d'equilibres k-ca a ete testee. Les sommes cationiques etant constantes, nous avons fait varier les teneurs relatives en potassium et en calcium (respectivement de 0,4 a 8,7 et de 0,1 a 8,4 meq. L#-#1). Cet essai a montre que la negrette est sensible aux variations de composition cationique de la solution nutritive, que ses besoins en potassium sont faibles et qu'elle absorbe facilement cet element. En essai de longue duree, trois des solutions precedentes ont ete etudiees: une solution temoin (k:3,9-ca:4,8 meq. L#-#1), une solution faible en potassium (k:0,3-ca:8,4 meq. L#-#1), une solution riche en potassium (k:7,1-ca:1,6 meq. L#-#1), ainsi que la solution temoin surchargee en calcium pour simuler un chaulage (k:3,9-ca:13,8 meq. L#-#1). Ce deuxieme essai a confirme les resultats de la premiere experimentation sur la partie vegetative. Sur les mouts, l'augmentation de la concentration du potassium dans la solution (et la baisse du calcium) entraine celle de la teneur en cet element (+3,7 g. L#-#1), du ph (+0,4 unite) et de la concentration en acide malique (+7 g. L#-#1) ; d'autre part, la surcharge en calcium entraine une diminution de ces trois parametres (respectivement de 0,7 g. L#-#1 ; 0,1 unite et 1,9 g. L#-#1). Des microvinifications ont montre que les variations du ph sont amplifiees dans les vins (+0,8 unite entre les solutions (k:0,3-ca:8,4 meq. L#-#1) et (k:7,1-ca:1,6 meq. L#-#1) ; -0,2 unite entre les solutions (k:3,9-ca:4,8 meq. L#-#1) et (k:3,9-ca:13,8 meq. L#-#1)), confirmant le role important joue par les equilibres cationiques, en particulier par le potassium dans l'acidite des vins

Abstract:
Le constat que la qualité du vin prend ses origines dans le vignoble est bien enraciné dans la culture européenne.

L'enjeu général s'inscrit dans une meilleure compréhension des mécanismes qui sont à la base du fonctionnement de la vigne et de la qualité du vin ainsi que cette étude vise la recherche des terroirs où le taux des stilbènes des vins est le plus élevé. Nous avons considéré deux réseaux de parcelles, l'un de Cabernet franc dans le Saumurois-Touraine (France) et l'autre de Sangiovese di Romagna (Italie). La caractérisation des terroirs et l'analyse des stilbènes des vins issus de chaque parcelle ont été étudiées sur de plusieurs années (de 2003 à 2005 en France, en 2008 et 2009 en Italie) Nous avons identifié cinq UTB dans le Saumurois-Touraine et trois UTB dans le Sangiovese di Romagna. Nos résultats montrent bien que le terroir affecte le métabolisme des stilbènes d'une façon importante et en particulier la teneur en transresvératrol dans le Saumurois-Touraine dépend pour le 58% du terroir. L'effet du millésime (climat) est dominant tandis que l'effet du sol et du sous-sol est secondaire au climat.

The observation that the quality of wine takes its origin in the vineyard is well rooted in the European culture. In this way, the viticultural zoning allows to characterize and to develop the 'Terroir'-based products also considering the recent increased consumers' attention on functional foods (that combine nutritional and healthy properties due to the high concentration of bioactive compounds as vitamins and phenols). Therefore, this study aims at identifying viticultural areas which can maximize the concentration of stilbenes in the wine using a 'Terroir' approach. We have considered fourteen vineyards of Cabernet franc in Saumurois-Touraine (France) and fourteen vineyards of Sangiovese in Romagna (Italy). The characterization of 'terroir' was carried out over three years in France (2003-2005) and over two years in Italy (2008-2009) along with determination of wine stilbene concentration. Five UTB (Terroir-based Unit) were identified in Saumurois-Touraine and three in Romagna. 'Terroir' significantly affected the metabolism of stilbenes and the level of trans-resveratrol in Saumurois-Touraine was influenced for 58% by 'Terroir'. The effect of the year (climate) was dominant whereas the effect of soil and sub-soil was secondary to climate. The vineyard elevation and the active-lime in the soil enhanced resveratrol content in wines. The soil texture affected the stilbene metabolism so the clayiest soil increased their wine concentration

The increase in the frequency and intensity of extreme weather events is one of the main effects of climate change, with particularly negative consequences for the development of agricultural activity. As water is one of the most limiting factors in yield, irrigation management is a critical factor for the future in a context of water scarcity. This study aims to implement three irrigation regimes (irrigation deficit with 25% and 50% of crop evapotranspiration (ETc) and full irrigation (100% ETc)) and two pruning systems (unilateral Cordon and Guyot) and evaluate their effects on physiological, agronomic and quality parameters in the Touriga Franca (Vitis vinifera L.) variety, in a commercial vineyard located in the Douro region. Field studies were carried out during 2019 in a commercial organic vineyard, located at Quinta do Romeu (41º53´02´´N, 7º08´00´´W, 326 m altitude) in the Northeast of Portugal. Agronomic, physiological and grape quality parameters were evaluated in the different treatments. The results showed that the plants that received the highest amount of irrigation were the ones that showed the best physiological and agronomic performance. In most of the quality parameters of the musts, no differences were observed between treatments, except for the total soluble solids (TSS) content. The deficit irrigation treatment (25% ETc), pruned in Cordon, showed the lowest values, while the 100% ETc full irrigation treatment pruned in Guyot was the one with the highest values. The results presented are from the first year of trials in a study that will take place over several years. Thus, the conclusions presented are still preliminary.
O aumento da frequência e intensidade dos eventos climáticos extremos é um dos principais efeitos das alterações climáticas, com consequências particularmente negativas no desenvolvimento da atividade agrícola. Sendo a água um dos fatores mais limitantes da produção, a gestão da irrigação é um fator crítico para o futuro num contexto de escassez de água. Este estudo tem como objetivo implementar três regimes de irrigação (deficit de irrigação com 25% e 50% de evapotranspiração da cultura (ETc) e plena irrigação (100% ETc)) e dois sistemas de poda (cordão unilateral e Guyot) e avaliar seus efeitos em parâmetros fisiológicos, agronómicos e de qualidade na variedade Touriga Franca (Vitis vinifera L.), numa vinha comercial localizada na região do Douro. Os estudos de campo foram realizados durante o ano de 2019 em uma vinha orgânica comercial, localizada na Quinta do Romeu (41º53´02´´N, 7º08´00´´W, 326 m altitude) no Nordeste de Portugal. Foram avaliados parâmetros agronômicos, fisiológicos e de qualidade da uva nos diferentes tratamentos. Os resultados mostraram que as plantas que receberam maior dotação de rega foram as que apresentaram um melhor desempenho fisiológico e agronômico. Na maioria dos parâmetros de qualidade dos mostos não se observaram diferenças entre os tratamentos com exceção do teor em sólidos solúveis totais (TSS). O tratamento de rega mais deficitária (25%ETc) podado em cordão foi o que apresentou os menores valores, enquanto o tratamento de rega plena 100%ETc) podado em Guyot foi o que apresentou valores mais elevados. Os resultados apresentados dizem respeito ao primeiro ano de ensaios do estudo que vai decorrer ao longo de vários anos. Assim, as conclusões apresentadas são ainda de caracter preliminar.

Abstract:
Biochar technology is a rapidly growing field of interest within the scientific community due to its multifunctional functions. This study aims to assess the impact of the application of different types of biochar on specific soil fertility parameters. To conduct this study, four different types of plant residues (Vine (Vitis vinifera L.), Tomato (Solanum lycopersicum L.), Banana (Musa), and Carnation (Dianthus caryophyllus. L.)) were used to produce biochar through slow pyrolysis system at 300°C and 500°C. The experiment was designed in randomized complete block with five replications and nine treatments. The treatments included the Control, Vineyard biochar (300°C and 500°C), Tomato biochar (300°C and 500°C), Banana biochar (300°C and 500°C), and Carnation biochar (300°C and 500°C). The trial consisted of a total of 45 pots. Each pot contained 10 kg of soil and 80 g of biochar (equivalent to 20 tons ha−1) strongly mixed and incubated for 300 days. At the end of the incubation period, the biochar treatments were found to improve specific soil fertility parameters (pH, EC, CEC, soil penetration resistance, and bulk density) compared to the control. The use of biochar as a soil enhancer proved to be an effective method for managing soil fertility. This research provides valuable insights into the potential benefits of biochar in sustainable agriculture.
