The Effects of Water Deficit on Leaf and Stoma Morphological Properties of Wine Grapes in Thrace Region

Abstract

This study was conducted on the semi-controlled conditions on Papazkarasi (Clone 289), Adakarasi (Clone 153), Karalahana, Yapincak (Clone 175), Vasilaki, Cabernet-Sauvignon and Sauvignon Blanc grap varieties which grown intensely in the Thrace Region during the 2019 vegetation period. Changes in leaf and stoma features of grape varieties were examined under different water deficit scenarios. While the genetic characteristics of the cultivars were found statistically significant in terms of the criteria examined, the effect of water deficit was only significant for leaf areas. As a result, it was considered that the morphological and physiological characteristics of the cultivars should be evaluated in the adaptation strategies that developed to sustain viticulture under the effects of the climate crisis.
