The possible cause of low fruit set in 0900 Ziraat sweet cherry (Prunus avium L.) was investigated. Pollination conditions, ovule development, incompatibility, and fruit set were evaluated under natural conditions. Results indicated that pollen transfer to the stigmas was sufficient, and pollen tube growth was normal. Ovule development in most pistils examined was not normal, and this was likely the cause of the low set in this cultivar.
