A multidisciplinary approach to grapevine zoning G.I.S. technology based: an example of thermal data elaboration

Abstract

[English version below]

Un grand nombre d’études ont été consacrées à l’évaluation quantitative des effets de climat sur la qualité des vignes, dans différents contextes climatiques. Généralement, la vocation viticole d’un terroire peut être étudiée par des approches mono ou multidisciplinaires. Les approches viticoles de zonage, laissent augmenter notre connaissance sur la complexe réalité des interactions de la vigne avec l’environnement, afin d’évaluer le niveau potentiel de qualité du raisin.
Dans cette étude nous suggérons une approche multidisciplinaire au zonage, basée sur la tecnologie G.I.S. (system geographique informatisé). La méthode permet nombreuse combinaisons possibles des informations, par exemple: des données climatiques (température de l’air, précipitations, direction du vent, rayonnement global et direct), avec les informations de la vigne (les exigences de chaleur nécessaires pour obtenir un niveau de maturation du raisin, de l’evapotranspiration potentiel quotidien), ou les informations de sol (pente, géologie, topographie), afin d’analyser leurs corrélations.
La méthode peut considérer différentes approches préliminaires à l’élaboration de données sur la base du type de données (par exemple: un facteur climatique) considéré. Dans le présent contribuez un exemple de l’élaboration thermique de données (température de l’air), combinée avec l’information dérivée des besoins de chaleur d’un groupe de 22 varietees est présenté, sur la base d’une expérience conduite dans un secteur de la province de Bénévent (Campania, Italie méridionale).
Dans l’exemple proposé, lesdites informations thermiques avec l’index bio-climatique d’Amerine-Winkler, laissant obtenir une subdivision du terroir considéré dans cinq secteurs, accordant leur convenance thermique (de moins de 1200 à 2000 degrées-jours). Selon le modèle, il était possible d’élaborer une carte de la convenance thermique des varietees considérées, étant possible d’avoir un placement optimal des vignes dans les diverses zones du terroire considéré.

A large number of studies have been devoted to the quantitative assessment of the climate effects upon the quality of vineyards in many different climatic contexts. Generally the grapevine vocation of a territory may be studied through mono or multidisciplinary approaches.
Viticultural zoning approaches permit to increase our knowledge on the complex reality among grapevine and environment interactions, in order to evaluate the potentiality of an area necessary to obtain a data level of grape quality.
In this study we will to suggest a multidisciplinary approach to zoning, G.I.S.-technology-based. The presented method permit possible combinations of “information layers”, for example: climatic data (air temperature, rainfalls, wind direction and velocity, global and direct radiation), with grapevine informations (thermal needs necessary to obtain a data maturation level of the grape, daily potential evapotranspiration), or soil informations (slope, geology, topography), in order to analyse their correlations. According the method, is possible to present the obtained results clearly on builted computer maps. The method may consider different preliminary approaches to the data elaboration (maked with a specific computer program) on the basis of the type of data (for example: a climatic factor) considered.
In the present contribute an example of thermal data elaboration (air temperature) combined with the information derived from the heat requirements of a group of 22 grapevines is presented, on the basis of an experience conducted in an area of the province of Benevento (Campania region, southern Italy). In the proposed example, the method combine the said thermal informations with the Amerine–Winkler bioclimatic index, permitting to obtain a subdivision of the considered territory in five areas, according their thermal suitability (from less than 1200 to 2000 degree-days).
Through the model it was possible to elaborate a map of the thermal suitability of the considered grapevines, being possible to have an optimal placing of the grapevines in the various zones of the considere
d territory.

Volatile composition of base wines to obtain sparkling wines from seven autochthonous grape varieties from Castilla y León (Spain)

The aim of this work was to characterize the aromatic profile of white and rosé base wines for the elaboration of sparkling wines from seven autochthonous grape varieties of Castilla y León. The ‘Albarín’, ‘Godello’ and ‘Verdejo’ white grape cultivars contribute with more fruity notes than the ‘Viura’ and ‘Malvasía’ cultivars; and ‘Prieto picudo’ coloured grape cultivar has more fruity character than ‘Garnacha’.

Il Soave: esempio di cultura e di scienza

L’evoluzione del settore viti-enologico, supportato dalla ricerca ci propone sempre più frequentemente vini unici e inconfondibili. Il merito di ciò è da ricercare nel rapporto vitigno-territorio e dalla

Management of grapevine water status with the DSS Vintel® provides evidence of sustainable irrigation strategies while maintaining wine quality of Pinot gris in Friuli-Venezia Giulia region, NE italy

Deficit irrigation strategies can be valuable means to improve grape quality while saving important amounts of water. A simple way to use deficit irrigation can be based on irrigating a vineyard with a determined level of crop evapotranspiration. Using a precise physiological parameter indicating water status, irrigation could be managed to maintain a specific pre-dawn leaf water potential.

Influence of viticulture on the temporary evolution of the landscape: the case of the AO Ribera del Duero (Central Spain)

The European Landscape Convention (ELC, 2001) defined the landscape as the “part of a
territory as perceived by the population and resulting from the action of natural and/or human factors and their interrelationships”. Wine landscapes, protected or not under figures such as cultural landscapes or Cultural heritage, are a clear demonstration of this definition, denoting the interrelationships of the natural
environment and the action of the human, which modulates the territory to give the different wine
landscapes. This work was focused on the study of the effect of the human factors linked to the cultivation of the vine on the modification of the landscape.

Assessment of antimicrobial effect of chitosan extracted from different sources against unwanted wine microorganisms

During wine production process high attention to the microbiological control from fermentation of the grape must to bottling is necessary. In fact, control of the indigenous microflora of the grape ensures correct fermentation activity of the inoculated starter, while control of the microorganisms in the finished wine is essential to prevent wine spoilage and to ensure the dominance of the desired bacteria when malolactic fermentation is required (Mas and Portillo, 2022).
