Özet

Olive is one of the oldest fruit species cultivated. This study was carried out to determine the stomatal and leaf morphology as well as the chlorophyll and carotenoid content of 10 different (seven domestic and three foreign) olive cultivars grown in Hatay/Türkiye ecological conditions. Stoma density: 369.44 (‘Gemlik-21’)–695.55 (‘Domat’) stoma/mm2; stoma index: 1.24 (‘Girit Zeytini’)–1.85 (‘Arbequine’); Chl(a +b): 20.66 (‘Frantoio’)–34.77 (‘Girit Zeytini’) mg/g FW; number of carotenoids: 1.98 (‘Arbequine’)–4.60 (‘Frantoio’) mg/g FW; leaf area varied between 2.29 (‘Girit Zeytini’) and 6.91 (‘Frantoio’) cm2. As a result of the correlation analysis, a positive correlation was found between stoma width and stoma length (r = 0.55, p < 0.0001). Although there was a negative correlation between leaf area with stomatal density, there was a statistically significant difference (r = −0.30, p < 0.0001). Similar results were observed between Chl(a +b) and carotenoids (r = −0.25, p < 0.01). According to principal component analysis, the first five components explain 79.08% of the total variation. According to the position plot corresponding to the correlations of olive cultivars with respect the two principal components the ‘Gemlik 21’, ‘Memecik’, ‘Edincik Su’ and ‘Gemlik’ varieties are in one group, ‘Frantoio’, ‘Manzanilla’, ‘Arbequine’ varieties are in one group, while ‘Ayvalık’ and ‘Domat’ varieties are in another group, and ‘Girit Zeytini’ are separate from other varieties.
