Determination of some fruit characteristics of local apple cultivars grown in Diyarbakır (Silvan, Sur and Hazro).

This study was conducted in 2023 to determine the morphological, physiological, pomological and some chemical properties of local apple genotypes grown in the neighborhoods of Silvan, Sur and Hazro districts of Diyarbakır province. In the study, fruit and tree characteristics of 30 apple genotypes were determined. As a result of the observations, it was determined that bud burst occurred between 9-21 March, the beginning of flowering occurred between 23 March-2 April, full bloom occurred between 2-12 April, the end of flowering occurred between 10-21 April and harvest dates occurred between 20 June and 20 September. It was determined that the number of days was 77-177 days. Fruit weight of the local apple genotypes examined was 18.6-140.2 g, fruit size 0.73-1.06 mm, fruit shell thickness 0.18-1.04 mm, fruit flesh hardness 3.53-8.5 kg/ cm², TEA value 9.6-18.5%, TEA value 0.38-2.35%, pH value 2.77-4.26, fruit skin color values L* 44.26 -78.38, a* -8.90 -33.16 b* 28.62 -61.05, meat color values L* 57.40-83.50, a* -5.98-28.62, b* 17.03-50 It was determined that .67, total phenolic substance amount was between 49.98-98.3 mg GAE/100 g and total antioxidant capacity was between 4.09-9.66 µmol TE/g.
