Estudio de la adaptación y del comportamiento productivo y enológico de variedades blancas foráneas en la zona vitícola del Penedés

L’A.O.C. Muscat de Rivesaltes prévoit l’utilisation de 2 cépages Muscats : le Muscat à petits grains (M.P.G) et le Muscat d’Alexandrie (M.A).

The recent effects on temperature and rainfall caused by global warming pose a serious threat to the wine industry worldwide, mainly in terms of a loss of quality in the wines produced.

Modern winemakers must ensure effective alcoholic fermentation without losing the intrinsic biodiversity of the different oenological contexts. In this sense, the population of saccharomyces cerevisiae characteristic of wineries that traditionally do not use selected yeasts can represent an interesting reservoir of biodiversity.

Context and purpose of the study. As other perennial crops grapevine is facing the challenges of climate changes. One of the major issues is global warming and variations of the water budget.

‐Evaluation of xylem embolism is an important challenge in identifying drought tolerant genotypes within the context of climate change.
