Dioik F. carica L.’da Sikonyumların Yapısal ve Mevsimsel Farklılıkları

Bu araştırma, diok Ficus carica’nın sikonyumları üzerine yapılan ilk detaylı ve kantitatif çalışmanın bir parçasıdır. İncir ağaçlarının fenolojisini ve cinsel özelliklerini araştırmak için sikonyumlar toplandı. Asenkron sikonyum oluşumu popülasyon düzeyinde gözlendi. Sikonyumların yılda üç kez meydana geldikleri görüldü: ilkbaharda (aralık-mart), yaz aylarında (temmuz-eylül) ve sonbaharda (eylül-kasım). Sikonyumun yapısı oldukça farklı bir oluşum sergiler; ostiolü çevreleyen pul benzeri brakteler, reseptakulm ve çiçeklerden oluşur. Erkek çiçekler, sikonyumun iç yüzeyinde bulunan doku üzerinde oluşurlar. Sikonyumlar ilkbahar, yaz ve sonbahar dönemlerinde incelendiğinde ilkbahar ve yaz aylarında gal ve dişi çiçeklerin morfolojik farklılıklar gösterdiği oysa ki erkek çiçeklerde hiçbir farklılığın olmadığı açıktır. Sonuç olarak F. carica’da sikonyumlar hayatta kalmak için değişiklikler oluşturmuşlardır. Bu çalışmada sikonyumların oluşumu ve gelişim zamanları araştırılmış ve birbiriyle karşılaştırılmıştır.

Structural and Seasonal Differences of Syconia in Dioecious F. carica L.

This research is part of the first quantitative, detailed study on the syconia in dioecious Ficus carica. Syconia were collected to research thephenology and sexual speciality of fig trees. Asynchronous syconium production was observed at a population level. They occurred threetimes yearly: in spring (December to March), in summer (July to September) and in autumn season (september to November). Syconiumstructure chart out quite differently; a syconium cosists of a receptacle, scale-like bracts surrounding the ostiole and flowers. Male, gall orfemale flowers bear into syconium, which are located on the inside surface of the syconium. We have been investigated the syconium inspring, summer and autumn periods. The morphological differences of gall and female flowers in spring and summer are obvious whereasthe male flowers do not show any differences. F. carica found out variation in the fruits (syconium) to his survival. In this paper, time offormation and development of syconium have been investigated and compared.
