Abstract :The seasonal changes in the some biochemical substances in fruits of ten persimmon cultivars insert ignore into journalissuearticles values( PCNA cultivars such as ‘O`Gosho’, ‘Fuyu’, ‘Hana Fuyu’ and ‘Jiro’, and non-PCNA cultivars such as ‘Vainiglia’, ‘ Hachiya’, ‘Kaki Tipo’, ‘Eylül’, ‘Amankaki’ and ‘Harbiye’); were determined in Dörtyol-Hatay insert ignore into journalissuearticles values(Turkey); in the 12 th and 13 th year after planting insert ignore into journalissuearticles values(YAP); . All results were expressed on a fresh weight basis. The fructose and glucose were the predominant soluble sugar in different persimmon cultivars, and the amounts of fructose and glucose in persimmon fruits showed an apparent increase during fruit development. The total phenolics insert ignore into journalissuearticles values(TP);, total flavonoids insert ignore into journalissuearticles values(TF); and soluble tannins insert ignore into journalissuearticles values(ST); concentration in fruits showed a continuous decrease from July to consumption maturity. The TP, TF and ST amounts of non-PCNA group fruits in tree maturity were higher more about 3.6, 4.9 and 5.6 fold than those of the PCNA group fruits, respectively. In consumption maturity, t he highest TP content of non-PCNA group fruits was found in ‘Eylül’ insert ignore into journalissuearticles values( 131.3 mg/100 g); and ‘Hachiya’ insert ignore into journalissuearticles values( 128.5 mg/100 g); cultivars. The fruits of non-PCNA cultivars had 2.3 and 1.9 fold more total antioxidant capacity insert ignore into journalissuearticles values(TAC); than those of PCNA cultivars according to FRAP and TEAC, respectively. In addition, t he results indicated that a good correlation between the TP content and TAC of persimmon cultivars insert ignore into journalissuearticles values(r = 0.98, at p <0.05);.
