A Study on the High Temperature Treatment to Three Grapevine Varieties Grown Under In vitro Conditions

Abstract

Increasing temperatures as a result of global warming cause climate change with precipitation regime. The drought, which is felt by the increasing effects of these factors, is among the most important threats limiting the development of plants. In recent years, research on the impact of global warming has been intensified. In vitro studies are one of the most effective methods used in the world in response to stress applications in a short time. In vitro studies should first develop the appropriate method depending on the plant type. In the literature review, no standard method of high temperature stress was found in vitro. Therefore, in this study, temperature grades and exposure times to stresses in plants belonging to some vine varieties grown in vitro conditions (Çalkarası, Öküzgözü and Narince) were determined. As a result of the study, 36 hours at 35˚C and 12 hours at 40˚C did not lose the vitality of the plants but seriously entered the stress. Therefore, in vitro selection technique
provides new opportunities for improving stress tolerance in grapevine for environmental sustainability
