ANALYSIS OF VULNERABILITY OF SOME WINE GRAPE VARIETIES UNDER TEMPERATURE CONDITIONS DURING VEGETATIVE RESTING STATE

Ionuț Dascălu, Nicoleta Mateoc-Sîrb

Abstract


It is well known that temperature is the main climate factor that influences the entire lifecycle of grape vine. Thus, at the same temperature level, grape vines respond differently depending on phonologic phase, cultivar, age, etc. In this paper, the authors present results of research pointing out the different response of wine grape vine varieties to negative thermal stress during the vegetative resting state. Research was carried out in the viticultural area Plenița - Plaiurile Drâncei grapevine plantation between 2014 and 2016, and aimed at monitoring and analysing data regarding thermal resources and negative thermal risk parameters, and cultivar vulnerability to critical temperature conditions. 


Keywords


vulnerability, wine grape varieties, vegetative resting, negative thermal stress, viticultural area.
