TAILIEUCHUNG - Pollen morphology of the genus Fritillaria L. (Liliaceae) in Turkey
Pollen grains of 39 taxa of the genus Fritillaria L. in Turkey were examined by light and scanning electron microscopy. Detailed pollen morphological characteristics are given for these taxa. Our investigation shows that the sculpturing of the exine provides valuable characters for separating species. | Research Article Turk J Bot 34 (2010) 397-416 © TÜBİTAK doi: Pollen morphology of the genus Fritillaria L.

Detailed pollen morphological characteristics are given for these taxa. Our investigation shows that the sculpturing of the exine provides valuable characters for separating species. In particular, sculpturing of the exine at the proximal face turned out to be taxonomically important. Six types of ornamentation were determined: reticulate, reticulate-perforate, suprareticulate, rugulate-reticulate, psilate-perforate, and perforate. On the basis of exine sculpturing, the sulcus membrane, and the apex sulcus, 5 main pollen types are recognised. Key words: Fritillaria, Liliaceae, pollen morphology, SEM, LM Türkiye Fritillaria L. (Liliaceae) cinsinin polen morfolojisi Özet: Türkiye’deki Fritillaria L. cinsine ait 39 taksonun polenleri ışık ve taramalı elektron mikroskobu ile çalışılmıştır. Bu taksonların detaylı polen morfolojik karakterleri verilmiştir. Çalışmamız, ekzin ornamentasyonunun türlerin ayrımında değerli karakterler sağladığını göstermiştir. Proksimal yüzde retikulat, retikulat-perforat, supraretikulat, rugulat-retikulat, psilat-perforat ve perforat olarak 6 ornamentasyon çeşiti saptanmıştır. Ekzin sulkupturu, sulkus membranı ve sulkus apeks özelliklerine göre 5 polen tipi fark edilmiştir. Anahtar sözcükler: Fritillaria, Liliaceae, polen morfolojisi, SEM, LM Introduction The species of .
