Palynology of Taxa of Crepis L. Genus Growing in Çanakkale, Türkiye

Abstract

This study investigated the pollen morphology of the taxa belonging to the genus Crepis L. collected from various localities in Çanakkale in 2015. Wodehouse (1935) and Acetolysis (Erdtman, 1960) methods were used in the research. Pollen morphologies of 3 species and two subspecies belonging to the Crepis L. genus were defined according to light microscopy (LM) and scanning electron microscopy (SEM) examinations. In LM, pollens are monad, radially symmetrical and isopolar. Pollens are suboblate and oblate spheroidal, Amb shape is inter-hexagonal-subtriangular. The pollen of the genus is tricolporate. The view from the equator is circular and oval. In the examinations made with LM, the ornamentation is echinulophate. Pollen has 15 lacunae as 3 poral, 6 abporal, 6 paraboral. Ornamentation is echinulophate; the tectum surface is microperforate. SEM micrographs of C. smyrnaea and C. commutata pollen show depressions at the corners of the polar field. The collapses are located on the paraboral lacunae and are distinctly lacuna-like. As a result, in this study, palynological features of C. smyrnaea DC., C. micrantha Czerep., C. commutata (Spreng.), C. reuterana Boiss. & Heldr. subsp. reuterana taxa were studied for the first time. C. smyrnaea DC. ex Froel. was collected for the first time in Çanakkale within the scope of this study, according to the type records in Flora of Turkey.

Öz

toplanılan Crepis L. cinsine ait taksonların polen morfolojisi araştırılmıştır. Araştırmada Wodehouse (1935) ve Asetoliz (Erdtman, 1960) yöntemleri kullanılmıştır. Crepis L. cinsine ait 3 tür ve 2 alt türün polen morfolojileri ışık mikroskobu (LM) ve taramalı elektron mikroskobu (SEM) incelemelerine göre tanımlanmıştır. LM incelemelerinde polenler monad, radyal simetrili ve izopolardır. Polenler suboblat ve oblat sferoidal, Amb şekli interhegzagonal-subtriangular biçimdedir. Cinsin polenleri trikolporattır. Ekvatordan görünüş sirkular, ovaldir. LM ile yapılan incelemelerde ornamentasyon ekinülofattır. Polenler 3 poral, 6 abporal, 6 paraboral olmak üzere 15 lakunaya sahiptir. Ornamentasyon ekinülofat, tektum yüzeyi mikroperforat bir yapıdadır. C. smyrnaea ve C. commutata polenlerinin SEM mikrograflarında polar alanın köşelerinde çöküntüler mevcuttur. Çöküntüler paraboral lakunalar üstünde bulunmakta ve belirgin olarak lakuna görünümündedir Sonuç olarak bu çalışmada C. smyrnaea DC., C. micrantha Czerep., C. commutata (Spreng.), C. reuterana Boiss. & Heldr. subsp. reuterana taksonlarının palinolojik özellikleri ilk defa çalışılmıştır. C. smyrnaea DC. ex Froel. Flora of Turkey’deki tip kayıtlarına göre Çanakkale’de ilk defa bu çalışma kapsamında toplanmıştır.
