Incidence de la nature du sol et du cépage sur la maturation du raisin, à Saint Emilion, en 1995

Plastic film covering is a technique largely used in viticulture to protect table grapes vines from adverse weather conditions and to reduce the negative effects of grapevine fungi disease. Plastic film composition affects solar radiation income inside the covering with effects on sunlight wavelengths in relation to different absorbance and reflectance. The interaction of selected light ranges with vines could influence grape ripening and yield and consequently influence shelf life.

Disease-resistant hybrid grape cultivars (DRHGCs) are hybrids of Vitis vinifera varieties with other Vitis species, and they are endowed with greater resistance to specific fungal diseases, enabling a potential reduction in the application of pesticides in the vineyard.

Dans le cadre d’une étude globale de l’influence du type de sol et de la conduite du verger sur la composition des pommes à cidre, une attention particulière est portée sur les facteurs amonts de la qualité comme

Aroma and mouthfeel cues are the main characteristics defining red wine quality. During wine tasting, perceptual and physical-chemical phenomena leading to mutual interactions between volatiles and non-volatiles sensory active compounds, can occur. Aroma perception depends on the release of volatiles from wine, that is affected by wine constituents present in the medium (Pittari et al. 2021; Lyu et al. 2021). Our aim was to evaluate the effect of the non-volatile wine matrix composition (polyphenols, PPh) on the release and perception of red wine aromas by an experiment of matrix enrichment.

Throughout centuries of anthropocentric breeding, plants have been selectively bred to enhance their quality traits and yield, often overlooking the importance of neglected attributes, like those involved in the interactions with beneficial microorganisms. This phenomenon led to an alteration in the distribution of photosynthetic products, shifting from defence mechanisms to growth, commonly described as ‘domestication syndrome’. Addressing the losses stemming from this condition is imperative just as unravelling the concealed communication between grapevines and beneficial microorganisms.
