Les activités peroxidasiques du raisin de quelques cépages de Roumanie

Aims: The aims of this study were to i) characterize the impact of geographical origin and viticulture treatments on Chilean Cabernet-Sauvignon, and ii) develop machine learning models to predict its quality. 

Ground water in the interior valleys of California is contaminated with nitrates derived from agricultural activities, primarily the over-fertilization of crops.

Aroma fraction of musts from grapes ‘Pedro Ximenez’ traditionally sun-dried and chamber-dried at 40 ºC and at 50 ºC during 8, 5 and 4 days respectively, destined for the production of sweet wines in Montilla-Moriles region (southern Spain) was studied.

Green cover in vine rows provides many ecological services, but can also negatively impact the crop, depending on the weed species. The composition of a vineyard weed community is influenced by many parameters. Ensuring an evolution of the vine row flora into a desired direction is therefore very complex. A key step towards this goal is to know which factors influence the establishment of the weed community and which types of communities are best suited for vineyards. In this study, we analysed the weed communities of several vineyards in the Lake Geneva region (379 botanical surveys on 117 plots), with the aim to highlight the links between soil management practices (chemical and mechanical weeding, mowing, mulching roll) and phytosociological profiles, biodiversity and selected functional traits (growth forms, life strategies, root depth). T

Nebbiolo (Vitis vinifera L.) is one of the most important wine red cultivar of North-west Italy. A better understanding of the complex relations among grape aromatic and phenolic maturity and environmental factors may strongly contribute to the improvement of the quality of Nebbiolo wines.
