Zeytin çeşitlerinde çiçek biyolojisi incelendiğinde erkek ve hermafrodit çiçek durumları değişiklik göstermektedir. Yapılan bu çalışma ile 3 farklı zeytin çeşidinin üç yıl süreyle Tarsus/Mersin ekolojisindeki erselik çiçek oranı tespit edilmiştir. Aynı zamanda döllenmeden sonra çeşitlere ait uygulamalarda meyve dökümleri belirlenmiştir. İncelenen çeşitlerde kendine verimlilik ile tozlayıcı kullanımının meyve tutumuna etkisini belirlemek amacıyla başlangıçta uygulamaya alınmış çiçek sayıları ile karşılaştırılması sonucunda yüzde meyve tutma değerleri belirlenmiştir. Çeşitlerin çiçeklerinin açılmasından meyve bağlama aşamasına kadar geçen sürenin ise 10 ila 15 günlük bir süreyi kapsadığı saptanmıştır. Erselik çiçek oranları yıllar bazında benzerlik gösterirken, en yüksek Domat çeşidinde bulunmuş, bunu Sarı Ulak ve Gemlik çeşitleri izlemiştir. Domat, Gemlik ve Sarı Ulak çeşitlerinde yapılan tozlama denemeleri sonucunda meyve dökümlerinin kendileme uygulamalarında en fazla olduğu saptanmıştır. Yabancı tozlama uygulamalarında ise kendilemeye göre daha az döküm saptanmış ve tozlayıcı kullanımının meyve tutumu üzerine olumlu etkisi görülmüştür.

Hermaphrodite Flower Ratios and Fruit Drop in Some Olive Cultivars
The intricacies of flower biology in olive cultivars reveal variations in the occurrence of male and hermaphrodite flowers. This study endeavours to ascertain the frequency of hermaphrodite flowers over a three-year period within the ecological context of Tarsus/Mersin. Simultaneously, post-fertilization fruit abscission rates specific to each cultivar were determined. By initially quantifying flower numbers and subsequently comparing them against fruit retention rates, this research aimed to elucidate the impact of self-pollination and cross-pollination on fruit set across the examined cultivars. The period from the opening of flowers to the stage of fruit setting was found to range from 10 to 15 days. While the ratios of hermaphrodite flowers remained similar across years, the highest ratio was observed in the Domat cultivar, followed by the Sarı Ulak and Gemlik cultivars. Pollination experiments conducted on the Domat, Gemlik and Sarı Ulak cultivars revealed that fruit drop rates were highest in self-pollination practices. Conversely, foreign pollination practices resulted in lower fruit drop rates compared to self-pollination, indicating a positive impact of pollinator use on fruit retention.
