摘要

秋冬季节的热状态对葡萄在寒冷气候下的适应和生存起着决定性的作用。本研究旨在评估1961-2021年间克拉约瓦山葡萄园休眠季节热状态的时间变化及其对葡萄藤的潜在影响，特别是其对寒冷的适应能力和对霜冻的脆弱性。使用以下观测和分析数据来评估具有负热应力势的参数和指标:最低和最高温度(日、月平均)、绝对最高和最低月温度、霜冻持续时间(天)、几个低温阈值的频率和霜冻发生前的温度。

THERMAL REGIME DURING COLD ACCLIMATION AND DORMANT SEASON OF GRAPEVINES IN CONTEXT OF CLIMATE CHANGES- HILLS OF CRAIOVA VINEYARD (ROMANIA)

The thermal regime during the autumn-winter seasons plays a decisive role in cold acclimation and survival grapevine in cold climates. This study aims at assessing the time variability of the thermal regime during dormant season, between 1961-2021, in the Hills of Craiova vineyard and its potential implications on the grapevine, especially regarding its acclimation to cold and its vulnerability to frost. The following observations and analytical data were used in order to assess parameters and indicators with negative thermal stress potential: minimum and maximum temperature (daily, monthly averages), absolute maximum and minimum monthly temperatures, the duration of frost (days), the frequency of several low-temperature thresholds and the temperatures preceding frost episodes.
