Cartes thématiques: applications au vignoble champenois

Abstract

Quel est l’intérêt des cartes en viticulture? Celles-ci répondent à plusieurs usages.
Formalisation au sein d’un référentiel codifié et normalisé de la connaissance relative au milieu, aux observations biologiques et aux pratiques culturales. Visualisation de la variabilité dans l’espace et dans le temps d’une information territoriale. Pilotage de stratégies d’exploitation ou de filière en intégrant les différentes facettes de la diversité du territoire.
La restitution cartographique des savoirs viticoles apparaît désormais comme un enjeu majeur pour développer une viticulture intégrée compatible avec les exigences de la préservation de l’environnement (DOLÉDEC et al., 1996) (LA VILLE, 1993). Cette perspective est aujourd’hui une réalité accessible grâce aux outils informatiques de traitement de l’informatique géographique : les SIG (Système d’Information Géographique).

Mesoclimate and Topography influence on grape composition and yield in the AOC Priorat

The Priorat AOC, which is situated behind the coastal mountain range of Tarragona, is characterised by a Mediterranean climate that tends towards continentality and has very little precipitation during the vegetation cycle

Phenolic acid characterization in new varieties descended from Monastrell.

Phenolic acids are phytochemicals that are expansively distributed in daily food intake. Phenolic acids are involved in various physiological activities, such as nutrient uptake, enzyme activity, protein synthesis, photosynthesis, and cytoskeleton structure in seeds, leaves, roots, and stems. Also exhibit antibacterial, antiviral, anticarcinogenic, anti-inflammatory, and vasodilatory activities due to their antioxidant property.

Aroma chemical profiles characterization of wines produced with moristel grapes harvested at different time points

The wine aroma is constituted by hundred of volatile chemical compounds that depend on many viticultural and oenological factors.

Mobile device to induce heat-stress on grapevine berries

Studying heat stress response of grapevine berries in the field often relies on weather conditions during the growing season. We constructed a mobile heating device, able to induce controlled heat stress on grapes in vineyards. The heater consisted of six 150 W infrared lamps mounted in a profile frame. Heating power of the lamps could be controlled individually by a control unit consisting of a single board computer and six temperature sensors to reach a pre-set temperature. The heat energy applied to individual berries within a cluster decreases by the squared distance to the heat source, enabling the establishment of temperature profiles within individual clusters. These profiles can be measured by infrared thermography once a steady state has been reached. Radiant flux density received by a berry depending on the distance was calculated based on a view factor and measured lamp surface temperature and resulted to 665 Wm-2 at 7cm. Infrared thermography of the fruit surface was in good agreement with measurements conducted with a thermocouple inserted at epidermis level. In combination with infrared thermography, the presented device offers possibilities for a wide range of applications like phenotyping for heat tolerance in the field to proceed in the understanding of the complex response of plants to heat stress. Sunburn necrosis symptoms were artificially induced with the aid of the device for cv. Bacchus and cv. Sylvaner in the 2020 and 2021 growing season. Threshold temperatures for sunburn induction (LT5030min) were derived from temperature data of single berries and visual sunburn assessment, applying logistic regression. A comparison of threshold temperatures for the occurrence of sunburn necrosis confirmed the higher susceptibility of cv. Bacchus. The lower susceptibility of cv. Sylvaner did not seem to be related to its phenolic composition, rendering a thermoprotective role of berry phenolic compounds unlikely.
