Projected impacts of climate change on viticulture over France wine-regions using downscalled CMIP6 multi-model data

Introduction

Winegrape is a crop for which the quality and the identity of the final product depends strongly on the climatic conditions of the year. By impacting production systems and the way in which wines are developed, climate change represents a major challenge for the wine industry (Ollat et al., 2021). 

Assessing major changes in the vineyard expected in the future is a highly uncertain exercise, as many factors might affect grapevine growth, cropping conditions and plant diseases. Most studies considering climate change impact focus on grapevine response to temperature and rainfall, either considering change in phenological timing (e.g. García de Cortázar-Atauri, 2017). Only few studies consider changes in phenological timing and climate conditions between key phenological stages (e.g. Sgubin et al., 2022). However, these studies do not account for each region specific training system and cultivar might be different, hence affecting grapevine phenology and water status.

Effects of grapevine leafroll associated virus 2 infection on leaf net photosynthesis, yield and berry quality in Vitis vinifera cv. Malbec

Grapevine leafroll associated virus 2 (GLRaV-2) is one of the most common damaging viral diseases in vines, causing significant reductions in photosynthesis, yield and grape quality. In this study, we tested the hypothesis that the leaf net photosynthesis and the transport of sugars to the berries is progressively reduced along the season in vines infected with GLRaV-2, and consequently, the yield (kg per plant) and total soluble solids (TSS) at the berry harvest-ripe stage are lower than non-infected vines.

Influence of genotype and water availability on respiratory costs and plant carbon balance in grapevines (Vitis vinifera L.)

Due to the important contribution of agriculture to the global carbon dioxide (CO2) balance, new techniques are currently being developed to accurately estimate the carbon balance of different crops. Field studies to date in grapevines have been based on carbon allocation and biomass accumulation dynamics.

Phenological behavior and evolution of maturation of grapes of juice preparation

The ripening level of the grape is one of the most important factors in the quality of its derivatives, because of the complex phenomena inherently related to the varieties and environmental conditions. The objective of the present study was to monitor the phenological development of the Chardonnay variety and to evaluate the influence of the different ripening points on the production of juices.
