THERMAL REGIME DURING THE GRAPEVINE'S VEGETATIVE DORMANCY IN THE BANU MĂRĂCINE VINE-GROWING AREA

Rezumat

The study conducted in the Banu Mărăcine wine-growing area during the grapevine dormancy period—covering the 2024/2025 and 2025/2026 viticultural years—has highlighted another dimension of climate change. Rising temperatures during the dormancy period can significantly impact the onset of the grapevine's growth cycle by triggering earlier budbreak. Over the last two years, the winters have been mild, with temperatures not dropping below - 11°C. Throughout all six months of the season, average temperatures remained higher than the long-term multi-year averages. The primary drawback of this situation is a substantial reduction in the grapevine's resistance to low temperatures—specifically those associated with late frosts—given that the frequency of such frost events has remained constant.
