High resolution remote sensing for mapping intra-block vine vigour heterogeneity

Abstract

In vineyard management, the block is considered today as the technical work unit. However, considerable variability can exist inside a block with regard to physiological parameters, such as vigour, particularly because of soil heterogeneity. To represent this variability spatially, many measurements have to be taken, which is costly in both time and money. High resolution remote sensing appears to be an efficient tool for mapping intra-block heterogeneity. A vegetation index, the Normalized Difference Vegetative Index (NDVI), calculated with red and near infrared leaf reflectance can be used as a vine vigour indicator. Because of the cultivation of vines in rows, a specific image treatment is needed. Only high resolution remote sensing (pixels less than 20 cm per side) allows the discrimination between row pixels and inter-row ones. The significant correlation between NDVI and pruning weight and the possibility to map the vigour with the NDVI by means of high resolution remote sensing, show the ability of NDVI to assess intra-block variations of vine vigour.

Effects of soil and climate on wine style in the Breede River Valley of South Africa: Sauvignon blanc and Cabernet-Sauvignon

Les effets du sol et du climat sur le style de vin ont été évalués pour des vignes irriguées à deux endroits différents de la vallée de la Breede, en Afrique du Sud. L’un des 2 endroits est cependant plus froid que l’autre, principalement en raison de températures nocturnes plus basses.

Interaction between commercial mannoproteins and phenolic compounds of two red wines from different Portuguese grape cultivars

The interaction between mannoproteins and wine phenolic compounds is a subject of great interest as some studies show the possible impact in color stability and an improvement in the sensory characteristics namely the reduction of red wine astringency.

A geologic numeric mapping, with geophysic transects, of Marsannay’s vineyard (Burgundy, France)

Marsannay est l’appellation la plus septentrionale de la Côte de Nuits, à la limite Sud de Dijon. Elle regroupe trois villages, Chenôve, Marsannay-la-Côte et Couchey, et constitue l’appellation la plus vaste de la Côte de Nuits avec 315 hectares en A.O.C. Elle possède uniquement des niveaux d’appellations régionales et communales depuis 1987.

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.

Viticultural zoning in the province of San Juan, Argentina. Preliminary results, year 2000

La région viticole de San Juan (Argentine) est marquée par des températures très élevées et des variations diurnes faibles. La valorisation de la connaissance de cet environnement et de ses interactions avec le fonctionnement de la vigne et le lien au vin passent par l’étude de ses terroirs et de leur caractérisation. Le point de départ de ce travail est l’étude des zones mésoclimatiques aptes à la culture de la vigne de la Province de San Juan et à la caractérisation des sols de cette même région. L’objectif est de définir le potentiel vitivinicole des zones considérées.
