Développement de l’appareil végétatif et maturation du raisin sur quatre sols de Pomerol en 1995

The plant rhizosphere microbial communities are an essential component of plant microbiota, which is crucial for sustaining the production of healthy crops. The main drivers of the composition of such communities are the growing environment and the planted genotype. Recent viticulture studies focus on understanding the effects of these factors on soil microbial composition since microbial biodiversity is an important determinant of plant phenotype, and of wine’s organoleptic properties. Microbial biodiversity of different wine regions, for instance, is an important determinant of wine terroir.

Hail damage can have a major impact on the vine’s physiological growth (defoliation, wood and cane damage) and can lead to significant yield and economic losses.

Climate change is increasing the frequency and severity of drought periods leading to significant impacts on agro‐economic activities

Context and purpose of the study. Cover cropping in vineyards supports grape yield, quality, and soil health.

Calcium (Ca) is an important nutrient for plants which plays key signaling and structural roles. It has been observed that exogenous Ca application favors the pectin accumulation and inhibition of polygalacturonase enzymes, minimizing fruit spoilage. Silicon (Si) is a non-essential element which has been found to be beneficial for improving crop yield and quality, as well as plant tolerance to diverse abiotic and biotic stress factors. The effect of Si supply to grapevine has been assessed in few investigations, which reported positive changes in grape quality and must composition.
