Researches on 0900 Ziraat Cherry Cultivar Prevent from Fruit Cracking
The study was carried out on 5 years old 0900 Ziraat sweet cherry cultivar which is grafted on MaxMa 60 rootstock, 5x5m planting distance. The trees were pruned as central leader system and cultivated in Niğde province at an altitude 1480m. The aim of this study is preventing from fruit cracking. The treatment’s specified for this purpose were applied; 0.5% Calcium Nitrate, 20ppm GA3, 100lt/ 300cc Green Miracle, 100lt/ 400gr Green Stim, water (control). In this research all applications were made in the same period. Pomological analyzes were carried out in order to determine the fruit quality criteria in the study where standard fertilization and irrigation programs were applied. Cracking indices were calculated in order to determine the effect of these applications on the resistance to cracking. According to the results obtained fruit weight was found to be higher in all treatments compared to control and it was obtained with Green Stim at the highest of 9.87 g. Fruit flesh hardness was measured with the highest Green Stim (72.65 Shore), Green Miracle (72.16 shore) and Calcium Nitrate (69.77 shore). According to the cracking index results, the lowest value was determined as 37.6 in Green Stim application and the highest value was measured in GA3 application (44.0) and control (Water) (45.2). The best results were obtained from the Green Stim application in terms of prevent fruit cracking ratio, on the other hand all applications reduced the cracking of the fruit.
