TAILIEUCHUNG - Pollen morphology of some Gypsophila L. (Caryophyllaceae) species and its taxonomic value

Pollen morphology of 12 taxa (6 of them endemic) that belong to the genus Gypsophila L. were investigated using light microscopy (LM), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). | Research Article Turk J Bot 33 (2009) 335-351 © TÜBİTAK doi: Pollen morphology of some Gypsophila L. (Caryophyllaceae) species and its taxonomic value Ebru ATAŞLAR*, İsmühan POTOĞLU ERKARA, Süleyman TOKUR Eskişehir Osmangazi University, Faculty of Science and Literature, Department of Biology, 26480 Eskişehir - TURKEY Received: Accepted: Abstract: Pollen morphology of 12 taxa (6 of them endemic) that belong to the genus Gypsophila L. were investigated using light microscopy (LM), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). Differences in pollen morphology between these taxa were determined based on palynological studies. Pollen grains are spheroidal and polyporate. The exine structure is tectate, but that of G. sphaerocephala var. sphaerocephala is intectate. The exine sculpture is granulate-microechinate-microperforate, but that of G. sphaerocephala var. sphaerocephala displays clavate-microechinate ornamentation. The operculum exists in the form of scattered pieces in G. curvifolia, while it exists as a whole in the other taxa. G. perfoliata var. perfoliata has the largest pollen grain diameter, whereas G. tubulosa has the smallest. The exine consists of 2 parts; the upper part is the thick ectexine and the lower part is the thin endexine. The endexine is thin and continuous. Key words: Caryophyllaceae, Gypsophila, pollen, LM, SEM, TEM Bazı Gypsophila L. (Caryophyllaceae) türlerinin polen morfolojileri ve taksonomik önemleri Özet: Gypsophila L. cinsinde yer alan altı tanesi endemik on iki taksonun polen morfolojileri ışık (LM), scanning electron (SEM) ve transmission electron (TEM) mikroskopları kullanılarak araştırılmıştır. Palinolojik çalışmalar sonucunda taksonlar arasındaki farklılıklar belirlenmiştir. Polenler sferoid ve poliporat’dır. G. sphaerocephala var. sphaerocephala’da ekzin yapısı intektat, diğer taksonlarda ise tektat’dır. Ekzin skulpturü G. sphaerocephala var. .
