Characterization of Mesoclimatic zones competent for the culture of vine (vitis vinifera l.) in the province of San Juan, Argentina

Abstract

Le zonage agroclimatique a pour objet de caractériser des lieux ayant des aptitudes distinctes pour la production de la vigne. La province de San Juan en Argentine est l’une des régions vitivinicoles les plus chaudes du pays. Cette étude a pour but de déterminer les zones aptes à la culture de la vigne, en se basant sur l’analyse du mésoclimat de cette province, et de définir l’aptitude viticole de ces zones et leur délimitation géographique.
Des indices écologiques sont calculés sur de longues séries de données, provenant d’un réseau de stations météorologiques. La comparaison de ces indices a permis de sélectionner les plus représentatifs et de grouper les mésoclimats similaires.
Dans la province de San Juan, six zones climatiques ont été définies, caractérisant le comportement de la vigne selon le type mésoclimatique. L’intégrale thermique de base 13°C et l’indice des températures minimales du mois avant récolte dans cette région chaude sont les variables principales qui permettent ce zonage.

The aim of an agroclimatic zoning is to characterize areas, which have different capacities for the vine growing production. The Province of San Juan is the hottest grapes and wines producing region of Argentine. This study aims at determine the zones in the province which are competent for the vineyards thanks to analysis of microclimate, and to define their agricultural and enological potential.
Ecological indices coming from databases of meteorological stations have been calculated. The comparison among these indices allowed to select the most representative of them and to gather similar mesoclimates.
In the Province of San Juan, six climatic zones have been characterized, each of them corresponding to a specific vine behaviour. This zoning has been made thanks to two main indices: the thermic integral basis 13°C and the indices of minimal temperature during the month before harvesting.

Spectral features of vine leaves are influenced by their mineral content

The reflectance spectra of vegetation carry potentially useful information that can be used to determine chemical composition and discriminate between vegetation classes. If compared with analytical methods such as conventional chemical analysis, reflectance measurement provides non-destructive, economic, near real-time data.

Effects of soil characteristics on manganese transfer from soil to vine and wine

Aim: In recent times the export of Beaujolais wines has been jeopardised due to a limit of manganese content (Mn) in wine implemented by China (2 mg/L), related to suspicions of potassium permanganate fraud. Nevertheless, soil Mn content may be high in some soil types in Beaujolais. The aim of this study was to improve knowledge of manganese transfer from soil to vine and wine because data on this subject is scarce.

The grapesim model: a model to better understand the complex interactions between carbon and nitrogen cycles in grapevines

Nitrogen fertilization is an important practice to guarantee vineyards sustainability and performance over years, while ensuring berry quality. However, achieving a precise nitrogen fertilization to meet specific objectives of production is difficult. There is a lack of knowledge on the impact of nitrogen fertilizers (soil/foliar; organic/mineral) and different levels of fertilization on the interactions between carbon and nitrogen cycles within the vine. Crop models may be useful in that purpose because they can provide new insights of the effects of fertilization in carbon and nitrogen storage. The objective of this study is to build a model to simulate grapevine carbon and nitrogen content in vines to evaluate the impact of different fertilization strategies in vine growth and yield.
