Relationships of Some Leaf Characteristics of Different Almond Varieties Grown in Semi-arid Climate Conditions

This study was carried out on some domestic and foreign late blooming varieties and their genotypes obtained as a result of hybridization in the almond collection parcel of Harran University Faculty of Agriculture in Sanliurfa/Turkiye in the summer period of 2020. In the research, 5 different cultivars and 6 hybrids were examined in the orchard. In the study, 3 trees of each variety and 9 leaves from 2 directions of each tree were taken. North and South directions were taken into account when taking leaf samples. According to the findings, when the leaf characteristics were examined in general, the highest values in terms of leaf width, leaf length, petiole length and leaf area were found in ‘Type-7’ hybrids among cultivars and hybrids. As a result of stoma analysis on the lower surface of the leaves, the highest overall average (196.47 unitsmm-²) was determined in Type-3, while the lowest (127.10 units/mm²) was found in ‘Ferragnes’ variety. As a result of the analysis, when all the average values were taken into account, it was determined that the leaf area was 16.74 cm², the average stomata density was 153.51/mm² and the leaf area was 256975.74/leaf stomata. It is thought that the study will be descriptive for almond varieties and hybrids grown in the same ecology.
