Özet

© 2020, Centenary University. All rights reserved.In order to reveal effects of cultivar, methods used (nail polish and transparented leaf method), picking positions of the leaves (shade / sun) and sampling from different parts of the leaf surface (tip, middle, bottom) on stoma density and sizes and determine total chlorophyll, chlorophyll a, chlorophyll b, carotenoid amounts and SPAD values of the cultivars, this research was carried out on 28 local grape cultivars grown in Hizan province in 2017. In the study, it was determined that the effect of the cultivar, method used and picking position of the leaf on the stoma density was important, but the effect of sampling from different parts of the leaf surface on the stoma density was insignificant. Similarly, it was determined that the effect of the cultivar, method used and on the stoma sizes was important, but the effect of picking position of the leaf and sampling from different parts of the leaf surface on the stoma sizes was insignificant. It was concluded that the transparented leaf method should be preferred in making better stomatal observation in the hairy and rough grapevine leaves. In the study, it was determined that the effect of the cultivar on total chlorophyll, chlorophyll a, chlorophyll b and carotenoid amounts and SPAD values was important and there were important differences between cultivars in terms of these values. It was observed that the SPAD values of the leaves in the sun were higher than the leaves in the shade.
