Abstract :

Purpose of this study was to determine pomological and some biochemical properties of 5 local and 2 foreign origin apples. In the study of the phenolic substances , cafeic 2.89 mg/kg and 8.18 mg/kg, Klorogenic acid ranged between 29.15 mg/kg and 194.45 mg/kg, epicatechin ranged between 24.51 mg/kg and 107.37 mg/kg, ; benzoic acid ranged between 6.71 mg/kg and 25.16 mg/kg. Of the organic acids; malic acid ranged between 1882.70 mg/kg and 7106.05 mg/kg, okzalic acid ranged between 4.70 mg/kg and 7.95 mg/kg, citric acid ranged between 24.10 mg/kg and 55.55 mg/kg tartaric acid ranged between 84.00 mg/kg and 382.55 mg/kg. According to macro and micro element analysis, the highest potassium and iron contents were observed in Uzun Yumra and Gelin Elması . In terms of pomological properties, average fruit height ranged between 53.93 mm and 65.82 mm, average fruit length ranged between, 64.86 mm and 76.56 mm, average fruit weight ranged between 96.99 g and 184.25 g. The tickest stalk tickness and longest stalk length were observed in Starking Delicious whereas the thinnest stalk thickness and shortest stalk length were observed in Kızıl Ahmedi. Brix ranged between %11.27 and %14.23 and fruit hardness ranged between 14.29 libre and 19.41 libre.
