Aspects concernant les relations entre quelques composantes de la biomasse viticole, en fonction de l’offre des ressources écologiques

Abstract

Les ressources écologiques représentent les facteurs de végétation, ou encore les facteurs de production, en expression quantitative. Celles-ci, utilisées par les plantes, transformées et organisées conformément à leur programme génétique, devieiment les composantes matérielles de la biomasse. Par la suite, les ressources écologiques peuvent être utilisées comme indicateurs synthétiques de l’offre écologique, nécessaires à l’analyse de favorabilité pour la compréhension des écosystèmes.

Pour les agroécosystèmes (AES) la récolte est un critère fondamental d’appréciation de la favorabilité des conditions écologiques naturelles, corrigées technologiquement, dans un souci d’efficience économique. Des recherches antérieures ont montré la diversité des relations entre les composantes de la biomasse ; celles entre vigueur et rendement, entre qualité et rendement présentent un intérêt particulier. Les résultats obtenus ont été souvent contradictoires ; cela est dû aux conditions diverses d’étude, à la spécificité biologique des individus, à l’offre des ressources écologiques naturelles corrigées de façon anthropique et aux mesures technologiques directes sur la forme de conduite des plantes et la charge en yeux.

Water deficit impacts grape development without dramatically changing thiol precursor levels

The use of new fungus disease-tolerant grapevine varieties is a long-term and promising solution to reduce chemical input in viticulture. However, little is known about the effects of water deficit (WD) on the thiol aromatic potential of new varieties coming up from breeding programs. Varietal thiols such as 3-sulfanylhexan-ol (3SH), 4-methyl-4-sulfanylpentan-2-one (4MSP) and their derivatives are powerful aromatic compounds present in wines coming from odorless precursors in grapes, and could contribute to the wine typicity of such varieties.

Terroir aspects of harvest timing in a cool climate wine region: physiology, berry skin phenolic composition and wine quality

Preliminary experiment of harvest timing was carried out in Eger wine district, Hungary in 2009. In situ physiological responses, berry quality parameters and wine quality of the Kékfrankos grapevine were studied at two growing sites (Eger-K6lyuktet6 – non-stressed, flat vineyard, and Eger-Nagyeged hill – water stressed, steep slope vineyard).

Geographical indication “Brandy Italiano”: study on the influence of wood barrel toasting and natural seasoning on endogenous and wood-derived compounds of aged distillates

The European geographical indication (GI) Brandy Italiano is exclusively reserved to brandy obtained in Italy from the distillation of wine from grapes grown and vinified in the national territory [1].

Metabolomic study of mixed Saccharomyces cerevisiae yeast during fermentation

Alcoholic fermentation conducted by microorganism is a key step in the production of wine. In this process, interactions between different species of yeast are widely described but their mechanisms are still poorly understood. The interactions studied in wine are mainly between Saccharomyces and non-Saccharomyces species. Therefore, little is known about the mechanisms of interactions

The dynamics of δ13C and δ18O in musts during berries development

Aim: Many processes or reactions that occur in plants involved isotopic discrimination. Water availability, for example, affects the isotopic ratio of carbon (δ13C) and oxygen (δ18O). In viticulture, δ13C is used in experiments related to water relations and irrigation in vineyards. δ18O is used much less but it could be a good complement to δ13C. The aim of this study was to generate knowledge on how these isotopic ratios, measured in musts, could help to better understand the water behavior of grape varieties.
