Abstract
In this study, it was aimed to determine the flowering pattern, the time from pollination to fertilization and the percentage of seed set during this time and also the capsule development after fertilization in sesame. The flowering pattern was studied in Muganlı-57 and Çamdibi varieties (with mono and tri capsules per leaf axil, respectively) and fertilization and capsule development were studied in only Muganlı-57.
Flowering pattern of mono-capsule type was very regular and simple in comparison with that of tri-capsule type. It was determined that pollen tubes reached ovarium within about 5.5 hours and fertilization was completed within about 11 hours after pollination. In unfertilized but induced by pollinated ovaries, carpel development was initiated but this development stopped in a short time. However, fertilized ovaries rapidly developed espicially after 4th day and reached maximum size in the 30th day after pollination.

Abstract
Bu çalışmada, susamda çiçeklenme modelinin belirlenmesi, tozlaşmadan döllenmeye kadar geçen sürenin ve bu sürede döl tutma oranının saptanması, döllenme sonrası kapsül gelişiminin incelenmesi amaçlanmıştır. Çiçeklenme modeli Muganlı-57 (tek kapsüllü) ve Çamdibi (üç kapsüllü) çeşidinde, döllenme ve kapsül gelişimi ise Muganlı-57 çeşidinde araştırılmıştır. Tek kapsüllü tiplerde çiçeklenme modelinin, üç kapsüllü tiplere göre daha düzenli ve basit olduğu saptanmıştır. Susam çiçeğinde tozlaşmadan ortalama 5.5 saat sonra polen tüpünün ovaryuma ulaştığı, tozlaşmadan yaklaşık 11 saat sonra ise döllenmenin tamamlandığı saptanmıştır. Döllenmemiş fakat tozlaşma ile uyarılmış yumurtalarda karpel gelişimi başlatılmış, fakat bu gelişme kısa bir süre sonra durmuştur. Oysa döllenmiş yumurtalardaki gelişim tozlaşmadan sonraki 4. günden itibaren belirgin bir artışla 30. günde maksimuma ulaşmıştır.
