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.

Scalable asymptomatic grapevine leafroll virus complex-3 detection through integrated airborne imaging spectroscopy, autonomous robotics, and cloud computing

The past three decades of terrestrial remote sensing research have delivered unprecedented insights into our fundamental ability to detect, quantify, and differentiate plant disease (Gold 2021). However, much of our fundamental knowledge in this domain has come from studies in non-agricultural systems and until recently, most agricultural studies, when extant, have focused on tree crops where canopy closure and large plot and plant size facilitate stress detection at low spatial resolution. Recent engineering innovations and advancements in constellation architecture design have refined the accuracy and scalability of airborne and spaceborne sensing platforms, enabling us to monitor diverse specialty crops, including grapevine, planted in smaller, spatially varied fields.

Functional characterization of grapevine MLO genes to define their roles in Powdery mildew susceptibility by CRISPR/Cas9 genome editing

Successful powdery mildew (PM) infection in plants relies on Mildew Resistance Locus O (MLO) genes, which encode susceptibility factors essential for fungal penetration. In Arabidopsis, loss-of-function mutations in three clade-V MLOs, AtMLO2, 6, and 12 confer complete resistance to PM infection. Since then, efforts are on to discover MLO genes contributing to PM susceptibility in many species to introduce mlo-based PM-resistance. Earlier studies in tomato and grapevine, using the RNAi approach, attributed PM susceptibility to SlMLO1, 5, and 8 and VvMLO3, 13, and 17, respectively indicating likely functional redundancy among MLOs.

From the current probabilistic approach to a deterministic production process, a clear step towards digital transformation in the wine sector

Currently, to consistently ensure the maintenance of a wine-style while benefiting from the utmost rigor made possible by the winemaking process, the composition of the wine blend is made using sensory control. This is performed after the wine is made with no real possibility of deterministic intervention.

Switch genes as a key to understand the grapevine ripening disorder berry Shrivel?

The ripening of grapevine berries encompasses complex morphological and physiological processes, especially at veraison. Berry shrivel (BS) is a ripening physiological disorder affecting grape berries with visible symptoms appearing short after veraison. The main symptoms of BS are a strong reduction in sugar accumulation, inhibited anthocyanin biosynthesis and high pH values. The most popular red grape cultivar in Austria “Blauer Zweigelt” (Vitis vinifera L.) is specifically prone to develop the BS ripening disorder and up to date a no specific cause or causes could be identified. Recently omics approaches have identified and characterized key processes during grapevine ripening. Among them a small subset of genes, called SWITCH, have been described as markers for the onset of the ripening process in fruits.
