This study was conducted during years 2013-2015 in a genetic resources garden located at the Black Sea Agricultural Research Institute. Eight cultivars of Trabzon persimmon registered by the Institute ('Kaplan', 'Ayder', 'Yeşilırmak', 'Onur', 'Akbulut', 'İrem', 'Türkay', 'Çoruh 1') and 1 standard persimmon cultivar ('Fuyu') were used for this experiment. Applying free pollination was compared to applying isolation on these species. The value of harvested fruits was determined in percent by comparing number of flowers to number of fruits retained; and by comparing the amount of fallen flowers, the number of harvested fruits and the number of flowers at the beginning of the application process. Also, some physical and chemical quality criteria was analyzed on the fruits. According to the results obtained, the average number of flowers fallen when applying pollination was 13.90% and when applying isolation it was 38.90%. The ratio of harvested fruits when applying pollination was 40.51% and when applying isolation it was determined to be 25.50%. Also, when applying natural pollination average fruit weight and the amount of dry matter dissolving in water were, in that order, 96.14 g and 16%; and when applying isolation it was determined to be 130.83 g and 25.50%.
