Grapevine vocs emissions triggered by elicitation –assessment of two french vineyards
2022
International audience; Grapevine foliar volatile organic compounds (VOCs) releases are induced by elicitor applications.Their emissions have been followed along the growing season on two geographically separatedBurgundy and Bordeaux (Chardonnay and Cabernet franc cultivars, respectively) French vineyards. Inyear 2019, fortunately lacking of endogenous disease, VOCs were collected under non-destructivemode, in four hours with SBSE sensors entrapped into a confinement Teflon bag. Then the monitoringof VOCs enables to distinguish between weak (COS-OGA (Bastid©) and CuSO4) and strong elicitors(MeJA).Although monoterpene Ocimenes are constitutively present among the scent of the twovineyards, t…

Metabolomic and cytological approaches to better understand grapevine trunk diseases disorders
2017
Grapevine trunk diseases (GTDs) are devastating diseases involving xylem-inhabiting fungi. Among them, Esca and Botryosphaeria dieback affect vineyards in major worldwide grape-producing areas. The causal fungi alter the woody issues and could produce toxins that disturb the plant physiology, leading to chronic or apolectic leaf symptoms. The unique effective fungicide against these diseases, sodium arsenite, is now prohibited because of toxicity. As GTDs are complex and still partly unknown, the identification of protection strategies remain a deadlock. Global and targeted approaches were therefore conducted to get new information on the impact of the diseases and sodium arsenite treatment…
