Abstract
Low yield is the main problem in many sweet cherry growing areas. Yield occurs with effective fruit set under favourable conditions. Development of floral organs at anthesis must be completed to realize sweet cherry fruit set. Especially, developmental stage of sweet cherry ovules at anthesis is related with fruit set. In this study, nucellus of primary ovules at anthesis was studied for two consecutive years in ‘0900 Ziraat’ sweet cherry variety and its clones (4503, 4218, 3501, 3503 and 3201) grafted on Gisela 5 and Mazzard seedlings rootstocks. Nucellus not completed in the interior of integuments was observed at anthesis stage. It was found that there was a statistically significant difference between the nucellus deformations of ‘0900 Ziraat’ and that of its clones. In addition, rootstocks were found to be partially effective on nucellus deformations
