Réponses phénologiques de la vigne à la variabilité climatique dans une région côtière de l'Uruguay

Abstract : Surface under vineyards are multiplying in the coastal region of eastern Uruguay and agroclimatic studies are being carried out in a commercial vineyard in the department of Maldonado. It aims at developing knowledge on climate of the new region compared to the traditional wine region of Uruguay and on the grapevine phenological responses to interannual climatic variability. Tannat and Albariño cultivars were monitored and climatic data were analysed during the 2012-2018 period. Results showed this coastal region is cooler than the traditional winegrowing region of the country. Rainfall over the growing season did not show significant differences, but the number of rainy days was statistically higher in Maldonado. Albariño and Tannat showed differences in its phenological cycle during the six years of study. Both cultivars showed sensitivity to climate conditions.
