Extension to the Saumurois-Touraine area of an Anjou-originated method for the characterisation of the viticultural terroirs. (Loire Valley, France)

Abstract

[English version below]

En Anjou, une méthode de caractérisation des terroirs viticoles a été développée. Elle utilise un modèle de terrain basé sur la profondeur de sol et son degré d’argilisation. Le modèle concerne des terrains issus principalement de roches mères métamorphiques et éruptives du Massif Armoricain. Cet outil de caractérisation des terroirs viticoles nécessite d’être adapté lorsqu’il s’agit d’ensembles géologiques très différents, en particulier sur sols d’apport et de roches mères tendres et poreuses du Bassin Parisien. Une meilleure compréhension de la réserve hydrique des sols apparaît être un critère important de l’interaction entre le milieu et la plante. Afin de mener à bien cette expérimentation, un réseau de parcelles d’étude a été mis en place sur cinq appellations d’origine contrôlée de la moyenne Vallée de la Loire.

In Anjou, a method for the characterisation of the viticultural terroirs has been developed. It uses a terrain model based on the depth of the soil and its clay content. The model applies to soils derived from metamorphic and igneous bed-rocks belonging to the Armorican Range. This tool for terroir characterisation needs to be adapted to different geologic systems, in particular to soils resting on soft and porous sedimentary bed-rocks belonging to the Parisian Basin. A better understanding of the water supply regime seems to be an important criteria of the interaction between the environment and the vine. To achieve this goal, a multisite network was established on five Appellations of Controlled Origin (A.O.C.) in the Mid-Loire valley.

Polyphenolic profile and dietary fiber content of skins and seeds from unfermented and fermented grape pomace

The valorization of winemaking byproducts is subordinated to the knowledge of their chemical characteristics. This work concerned the determination of the polyphenolic profile and the dietary fiber content of skins and seeds from unfermented and fermented pomace of different cultivars (Moscato bianco, Cortese, Arneis, Pinot Noir, Barbera, Grignolino, Nebbiolo), sampled from some wineries in the Piedmont area (Italy) during the 2020 harvest.

Study of fungal and bacterial laccases for the reduction of ochratoxin A content in model wine

Ochratoxin A (OTA) is a mycotoxin produced by several filamentous fungi infecting grape bunches (Penicillium and Aspergillus spp.), this toxin pass to must when grapes are crushed and later it is found in wine. Following the evaluations of the toxicity of OTA, European Commission Regulations have been promulgated introducing upper limits for OTA concentrations in various commodities (cereals, cereal products, dried vine fruit, coffee, wine, grape juice, baby foods and dietary foods for special medical purposes).

Entomopathogenic nematodes application for controlling Lobesia botrana in grapevine and their impact on grapevine quality 

Entomopathogenic nematodes (EPN) are well-known biological control agents combined with specific adjuvants that now allow their use against aerial pests. Lobesia botrana (Lepidoptera: Tortricidae) is one of the major harmful pests detected in worldwide vineyards. Previous studies demonstrated that the EPNs Steinernema feltiae and S. carpocapsae could control L. botrana. The hypothesis was that the best combination of EPN-adjuvant/timing (season/temperatures) will support the use of EPN in the vineyard against L. botrana with no impact on the grape performance.
