Stomatal density in various Turkish grape cultivars
AbstractIn this study the number of stomata per unit area and dimensions of the stomata were determined in 15 important Turkish grape cultivars which were 20 years old and grafted on Kober 5 BB rootstock. Number of stomata per mm(2) of area varied from 129 ± 18 to 254 ± 10, stomatal length ranged from 22.6 ± 2.6 µm to 28.3 ± 4.3 µm, and stomaml width from 13.6 ± 2.2 µm to 18.6 ± 3.2 µm among cultivars. The cultivars. having minimum and maximum number of stomata per unit area were Balbal and Pembe Gemre; Erenkoy Beyazi and Muskule had minimum and maximum stomata size, respectively. Correlations between the number of stomata per unit area and the stomatal length (r = 0.100), and width (r = 0.184), and between the stomatal length and width (r = 0.493) were not significant among cultivars.
On the other hand, Balbal, Hafizali and Yapincak were found to be more tolerant than the other cultivars.
The characteristics of the cultivars in relation to their drought tolerance and stomatal densities were discusse.
