Zonage viticole des surfaces potentielles dans la vallée Centrale de Tarija (Bolivie)

Abstract

[English version below]

La présente étude de zonage viticole a été faite dans la région de la vallée Central de Tarija(VCT), dans la ville de Tarija, au Sud de la Bolivie; une région avec plus de 400 années de tradition qui présente une vitiviniculture de haute qualité. La Vallée possède une surface total de 332 milles ha.; existant des vignobles entre 1660 y 2300 m.s.n.m. et dans ce rang d’altitude il existe 91 mille ha. avec un haut potentiel pour la culture de la vigne. Pour la détermination des surfaces homogènes de la région ont été considérés les aspects d’environnement avec l’aide d’images satellitaires, des cartes topographiques, des données climatologiques et des cartes géologiques ; pour déterminer les caractéristiques de la région pour la culture de la vigne. Au niveau climatique furent appliqués les indices du Système CCM Géo viticole développés par Tonietto & Carbonneau (2004), lesquelles considèrent des éléments thermiques (Indice Héliothermique), hydriques (Indice de sécheresse) et nictothermiques (Indice de Froid nocturne); nous avons identifié 8 types des climats différents dans toute la région. Dans les particularités du sol furent déterminés la morphologie et il a été géo référencié tous ses caractéristiques (analyses chimique et physique). S’ai fait une classification spécifique des critères de culture de la vigne pour déterminer l’aptitude du sol, en même temps ont été identifié les surfaces avec des limitants pour le conduit des vignobles. L’étude a pour objectif d’identifié les zones potentielles pour la culture de la vigne et de cette façon orienté son élargissement avec le support des politiques d’état et pertinente assistance technique au producteurs de cette région.

This study of vitivinicultural zonation was carried out in the region of the Central Valley of Tarija (VCT), in the Department of Tarija, southern Bolivia, a region with more than 400 years wine tradition which actually presents a high quality. The valley has an area of total 332 thousand ha.; vineyards exist between 1660 and 2300 m.a.s.l. and in this altitude range there are 91 thousand hectares with a high potential for growing grapes. In the determination of homogeneous areas of the region, we considered the environmental aspects through satellite images, topographic maps, weather data and geology maps; thus the characteristics of the region for growing grapes were defined. Considering climate, we applied the Geoviticulture Multicriteria Climatic Classification System developed by Tonietto and Carbonneau (2004) which considers a heliothermal index (HI), dryness index (DI)) and a cold night index (CI), in this way there were 8 different types of climates identified throughout the region. For the characteristics of soil we determinated its morphology and did chemical and physical analysis, all dates were georeferenced. We realized a classification including the specific requirements and limits of grape plants to determine the aptitude of the soil. This study aims to identify areas with high potential for growing grapes and thus directing the growth of the sector, with support of state policies and suitable technical assistance to growers in the valley.

VALORIZATION OF GRAPE WINE POMACE USING PULSED ELECTRIC FIELDS (PEF) AND SUPERCRITICAL CO₂ (SC CO₂) EXTRACTION

Wine grape pomace quantitatively and qualitatively represents the most important fraction of wine waste. Namely, this by-product makes ~ 20% of the total mass of vinified grapes, and it is characterized with high concentrations of polyphenolic antioxidants, as well as grape seed oil. Hence, valorization of wine pomace, as an alternative to traditionally employed disposal, has drown considerable interest in recent years. Earlier studies were mostly focused on the extraction of phenolics, while mechanisms enhancing the extraction of lipid fraction from grape pomace, as well as their impact on the grape seed oil quality are far less investigated.

Cell Walls Of Grape Mesocarp Possible Fining Agents For Red And White Wine

Clarification or fining of wines is a technique used in wineries to eliminate unwanted wine components, which negatively affect its quality. Clarification normally involves the addition of an adsorptive material that eliminates or reduces the presence of undesirable components. The problem is that many of the fining agents used in the industry contain allergens, such as caseinates or ovalbumin.

Hyperspectral imaging and machine learning for monitoring grapevine physiology

Rootstocks are gaining importance in viticulture as a strategy to combat abiotic challenges, as well as enhancing scion physiology and attributes. Therefore, understanding how the rootstock affects photosynthesis is insightful for genetic improvement of either genotype in the grafted grapevines. Photosynthetic parameters such as maximum rate of carboxylation of RuBP (Vcmax) and the maximum rate of electron transport driving RuBP regeneration (Jmax) have been identified as ideal targets for breeding and genetic studies. However, techniques used to directly measure these photosynthetic parameters are limited to the single leaf level and are time-consuming measurements.

Detoxification capacities of heavy metals and pesticides by yeasts 

Winegrowing is still characterized by the extensive use of chemical fertilizers and plant protection products, despite strong recommendations to limit these practices. A part of these xenobiotics and metals are then found in grape juice and wine, causing a major health concern, as well as negatively affecting the fermentation process. In recent years, there has been renewed interest in non-Saccharomyces yeasts. These species have a wide phenotypic diversity, which would be exploited to broaden the aromatic palette of wines.
