Design of an indicator of vine vigor potential conferred by soil (vipos), using a fuzzy expert system

Abstract

Winegrowers must adapt more and more their viticultural practices in order to evolve toward a sustainable viticulture, to be competitive and to improve both the production methods and the quality and typicalness of wines. In this context, ‘Terroir’ studies in Loire Valley vineyards have allowed to build decision aid maps that can be used directly by growers to adjust their practices. We focus here on the vigor potential conferred by soil (VIPOS) that especially allows adapting the choice of the rootstock. An algorithm had previously been proposed by Morlat (2001) to estimate VIPOS according to three main influencing variables: water holding capacity of the soil, gravel percentage on the soil profile and parent rock hardness. Nevertheless, the VIPOS estimation, based on this algorithm, had to be completed by expertise. The objective of the paper is to present a new method to estimate VIPOS using a fuzzy expert system that allows having an automatically continuous estimation.

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).

Terroirs and legal protection

Le concept AOC permet, par une délimitation précise, la mise en valeur de terroirs particulièrement adaptés à la viticulture. Seuls les terroirs ainsi identifiés peuvent produire des vins portant le nom de l’AOC. Le nom de cette AOC ne peut être utilisé que pour des vins issus de terroirs compris dans l’aire d’appellation, sous peine de sanctions pénales. La délimitation ainsi opérée participe à la protection du nom de l’AOC. A l’inverse, le terroir délimité n’est pas protégé.

Assessment of plant water consumption rates under climate change conditions through an automated modular platform

The impact of climate change is noticeable in the present weather, making water scarcity the most immediate mediator reducing the performance and viability of crops, including grapevine (Vitis vinifera L.). The present study developed a system (hardware, firmware, and software) for the determination of plant water use through changes in weight through a period. The aim is to measure the differences in grapevine water consumption in response to climate change (+4oC and 700 ppm) under controlled conditions. The results reveal a correlation between daily plant consumption rates and reference evapotranspiration (ETo).
