From local classification to regional zoning-the use of a geographic information system (GIS) in Franconia / Germany. Part 1: specific GIS applications in viticulture

Abstract

[English version below]

En vue d’une production économique de qualités des raisins optimales une connaissance des informations les plus différentes est importante. Les nouvelles technologies, telles qu’un SIG permettent de réunir les informations sur le terrain, la nature du sol, le danger d’érosion, le climat, la végétation, l’hydrographie, l’apparition de nuisible et de maladies, etc. Sur la base de cartes topographiques un SIG permet une vaste analyse, une appréciation des rapports complexes ainsi qu’une représentation cartographique. Sur la base de modélisations en trois dimensions du terrain avec le SIG, les ensembles de données saisies ainsi que leur classification au niveau local peuvent être utilisés dans la production de zonages régionaux. Les données du SIG délivrent des informations liées à la protection du sol et de l’eau, la classification climatique, la protection de la vigne, la possibilité d’enherbement, la planification d’irrigation, etc. Les aspects principaux de l’utilisation du SIG en Franconie sont l’enregistrement et l’analyse des données locales, comme les paramètres du sol, le risque d’érosion et les conditions climatique, dans le but d’élaborer des classifications locales des zones à appellation communale et des petits terroirs. A l’aide du SIG, ces classifications locales permettent la création de zonages régionaux, comme par exemple la formation de cartes régionales du risque d’érosion ou la définition de zones de climat local. La modélisation du terrain en trois dimensions permet de déterminer les couloirs d’écoulement de l’air froid et la modélisation des régions soumises au risque de gel, comme les creux et les vallées. Pour cette raison, le SIG en viticulture est un excellent instrument de travail dans la recherche et la consultation viticole ainsi que pour les producteurs de raisins et des domaines viticoles afin d’enregistrer, d’analyser et d’évaluer les influences que des zones régionales déterminées ont à subir. Ainsi le SIG montre aux vignerons leurs surfaces viticoles sous une perspective permettant de mieux analyser le milieu.

For an economically production of optimal grape quality, the knowledge of different types of information is important. New computer software such as a GIS enables the compilation of information on topography, soil, erosion risk, climate, vegetation, infrastructure, and the occurrences of pests and diseases. Based on digital topographie maps, a GIS allows a synoptical analysis of complex correlations and their representation on maps. Based on a three-dimensional terrain modelling with the GIS, recorded data sets and their local classification can be used to establish a regional zoning of viticultural relevant factors as e.g. favourable climatic zones combined with best soil conditions. The GIS data deliver information for fields like soil and water conservation, climatic classification, vine protection, selection of suitable grape varieties and rootstocks, green cover capacity, irrigation planning, yield and quality recording, etc. Main objectives of the GIS application in Franconia are the recording and analysis of local data sets as soil parameters, erosion risk and climatic conditions in vineyard sites. With help of the GIS, these local information enables the creation of a regional zoning of the respective data set, e.g. the generation of regional erosion risk maps or the definition of regional climatic zones. The 3D-terrain modelling allows the determination of flow-off paths of cold air and ‘mapping’ of frost endangered areas like depressions and valleys. Therefore, the viticultural GIS is an excellent aid to researchers and consultants, grape producers and wine growing estates for recording, analysing and assessing viticultural relevant factors in vineyards. This enables a new perspective of vineyards for a better planning of new plantings and also for an improvement of the vineyard management.

Aroma quality of fortified wines from different Moscato cv. Cultivated in sicily

AIM: Vitis vinifera L. cv. Moscato includes different varieties, mainly white grapes with a medium-sized berry, spheroidal or slightly flattened in shape, yellow greenish color which becomes golden yellow or amber when exposed to the sun. Moscato varieties are mainly used for the production of sweet aromatic wines

Linear sweep voltammetry to classify and characterize the antioxidant properties of tannins

In recent years, numerous studies have been carried out at the OIV on oenological tannins, both with regard to oenological properties and methods of characterization. The results of these recent studies have led to the revision of the general monograph and the drafting of four new monographs, one for each of the four chemical classes into which the tannins have been grouped: ellagitannins, gallotannins, procyanidins/prodelphinidins, profisetinidins/prorobinetinins.

Black foot disease in South African vineyards and grapevine nurseries

Over the last few years a drastic reduction has been noted in the survival rate of vine cuttings in nurseries, as well as in young vineyards in the Western Cape Province of South Africa. The low average take percentages of young vines can be attributed to several factors, including fungal, bacterial and viral diseases, insect and nematode pests,

Comparing vineyard irrigation management based in two different approaches: vegetation indices and SIMDualKc model

Water scarcity, high air temperatures, high vapor pressure deficit, and increasing frequency and intensity of extreme climatic events, namely heat waves, exert huge pressure on viticulture, as is the case of Mediterranean climates. Therefore, farmers rely more and more on irrigation to overcome these constraints. Deficit irrigation is a proved strategy to optimize irrigation efficiency and wine quality. The present study intends to demonstrate the application of precision techniques, namely remote sensing derived vegetation indices (VI) and an open source software, SIMDualKc, to compute crop evapotranspiration using the dual crop coefficient approach (Kcb + Ke), for deficit irrigation management.

Analysis of volatile composition of interaction between the pathogen E. necator and two grapevine varieties

Volatile organic compounds (VOCs) are emitted by nearly all plant organs of the plants, including leaves. They play a key role in the communication with other organisms, therefore they are involved in plant defence against phytopathogens. In this study VOCs from grapevine leaves of two varieties of Vitis vinifera infected by Erysiphe necator were analysed. The varieties were selected based on their susceptibility to pathogen, Kishmish Vatkana has the Ren1 resistance gene and Zamarrica showed high susceptibility in previous trials.
