Valorisation agroviticole de l’effet terroir par l’enherbement des sols

Abstract

Les études développées par l’INRA et l’UV, à Angers, concerne les terroirs viticoles et leur gestion optimisée, tant du point de vue agroviticole qu’oenologique. Les travaux antérieurs (Morlat, 1989) ont permis de donner une dimension scientifique au concept de terroir viticole et ont démontré l’influence considérable de ce facteur de production sur la qualité et la typicité des vins (Asselin et al, 1992). Une méthodologie de caractérisation intégrée des terroirs, s’appuyant sur « l’Unité Naturelle Terroir de Base » (considérée comme la plus petite unité spatiale de territoire utilisable dans la pratique, et dans laquelle la réponse de la vigne est homogène), a été mise au point (Riou et al, 1995).

Les terroirs identifiés et cartographiés selon cette méthode occupent une surface qui varie de quelques hectares à plusieurs centaines d’hectares. Ils peuvent constituer la base d’un zonage pour une région viticole, à partir duquel on peut envisager d’une part, une utilisation rationnelle de l’effet terroir à l’échelle de l’exploitation viticole, et d’autre part une gestion parcellaire des itinéraires techniques.

GrapeBreed4IPM: developing sustainable solutions for viticulture through multi-actor innovation targeting breeding for integrated pest management

According to the World Economic Forum and the European Union’s Biodiversity Strategy for 2030, the loss of biodiversity and the collapse of ecosystems are major threats facing humanity in the future.

Lamp – a modern tool for the detection of fungal infections in the vineyard

AIM: Loop-mediated isothermal amplification (LAMP) [1] is a modern technology for fast and sensitive amplification of specific DNA sequences under isothermal conditions. Its simple handling and no need for dedicated equipment together with an evaluation of the amplification event by in-tube detection make this method advantageous and economically affordable for on-site investigations in the industry.

Vine field monitoring using high resolution remote sensing images: segmentation and characterization of rows of vines

A new framework for the segmentation and characterization of row crops on remote sensing images has been developed and validated for vineyard monitoring. This framework operates on any high-resolution remote sensing images since it is mainly based on geometric information. It aims at obtaining maps describing the variation of a vegetation index such as NDVI along each row of a parcel.

MOVING FROM SULFITES TO BIOPROTECTION: WHICH IMPACT ON CHARDONNAY WINE?

Over the last few years, several tools have been developed to reduce the quantity of sulfites used during winemaking, including bioprotection. Although its effectiveness in preventing the development of spoilage microorganisms has been proven, few data are available on the impact of sulfite substitution by bioprotection on the final product. The objective of this study was therefore to characterize Chardonnay wines with the addition of sulfite or bioprotection in the pre-fermentation stage. The effects of both treatments on resulting matrices was evaluated at several scales: analysis of classical oenological parameters, antioxidant capacity, phenolic compounds, non-volatile metabolome and sensory profile.
