TAILIEUCHUNG - Pollen morphology of the genus Seseli L. (Umbelliferae) in Turkey
Morphological features of pollen of 11 Turkish taxa belonging to the complex genus Seseli L. were examined using light and scanning electron microscopy. On the basis of exine sculpturing, 3 main types were recognised in Seseli: Type 1, rugulate at equator, psilate-perforate at pole; Type 2, striate-reticulate at equator, rugulate at pole; and Type 3, rugulate at equator, striate at pole. | E.

On the basis of exine sculpturing, 3 main types were recognised in Seseli: Type 1, rugulate at equator, psilate-perforate at pole; Type 2, striate-reticulate at equator, rugulate at pole; and Type 3, rugulate at equator, striate at pole. The study revealed that palynological characters display taxonomic significance in the genus. Key words: Seseli, Umbelliferae, pollen, SEM Türkiye Seseli L. (Umbelliferae) cinsinin polen morfolojisi Özet: Sistematik açıdan karmaşık bir cins olan Seseli L. cinsinin Türkiye’de bulunan 11 taksonunun polen morfolojik özellikleri ışık ve taramalı elektron mikroskoplarında incelenmiştir. Seseli cinsinde ekzin ornamentasyon özelliklerinde üç tip fark edilmiştir (Tip 1: ekvatorda rugulat, kutupda psilat-perforat, Tip 2: ekvatorda striat-retikulat, kutupda rugulat, Tip 3: ekvatorda rugulat, kutupda striat). Bu çalışmada palinolojik karakterlerin cinsde taksonomik önem taşıdığı açıklanmıştır. Anahtar sözcükler: Seseli, Umbelliferae, polen, SEM Introduction The genus Seseli L. (Umbelliferae) contains herbaceous plants distributed in the IranoTuranian, Euro-Siberian, and East Mediterranean phytogeographic regions (Hedge & Lamond, 1972; Davis et al., 1988). The total number of Seseli taxa is about .
