Türkiye’deki Picris L. cinsinin polen morfolojisi ile ilgili ayrıntılı ilk araştırma bu çalışmada gerçekleştirilmiştir. Işık (LM) ve elektron mikroskobu (SEM) ile Picris L. cinsine ait 5 tür çalışılmıştır. Cinsin polen morfolojisi ışık mikroskobu incelemelerinde radyal simetrili, monad ve izopolardır. Polenler prolat sferoidal şeklinde olup amb interhegzagonal-subtriangulardır. Ornamentasyon ekinulofattır. Elektron mikroskobu mikrograflarında yapılan incelemelerde ornamentasyon ekinulofat-perforat, Picris cyprica Lack.ve Picris strigosa Bieb. türlerinde paraboral lakunalarda tektum yüzey ornamentasyonu retikülat, iki farklı lokaliteden toplanan Picris altissima Delile. türleri ve Picris kotschyi Boiss. polenlerinde ise paraboral lakunalardaki tektum yüzey ornamentasyonu mikroperforat olarak gözlenmiştir. Abporal lakunalarda tectum yüzeyinde gözlenen ornamentasyon tüm polenlerde psilattır. Polenlerde spinül boyları, spinül taban genişliklerinden daha uzundur. Spinüllerin uçları obtus-akut olarak sonlanmaktadır. Polenler 3 poral, 6 abporal, 6 paraboral olmak üzere 15 lakunaya sahiptir. Polenlerin elektron mikrograflarında polar bölgelerinde çökme olduğu bariz olarak gözlenmiştir.

Pollen Morphology of Five Species of Picris L. (Asteraceae)

Öz

The first detailed research on the pollen morphology of the Picris L. genus in Turkey was carried out in this study. Light (LM) and electron microscopy (SEM) studied five species of the genus Picris L. The pollen morphology of the genus is radial symmetrical, monad and isopolar in light microscopy examinations. Pollens are in prolate sferoidal shape, and amb is inter-hexagonal-subtriangular. Ornamentation is echinulophate. In the examinations made in electron microscope micrographs, ornamentation is echinulophate-microperforate, and tectum surface ornamentation is reticulate in paraboral lacunae in Picris cyprica Lack. and Picris strigosa Bieb. species. In the pollen of Picris altissima Delile. species and Picris kotschyi Boiss. collected from two different localities, the tectum surface ornamentation in the paraboral lacunae was observed as microperforate. The ornamentation observed on the tectum surface in abporal lacunae is psilate in all pollens. Spinule lengths in pollen are longer than spinule base widths. The ends of the spines terminate obtus-acutely. Pollen has 15 lacunae, 3 poral, 6 abporal, 6 paraboral. In the electron micrographs of the pollen, it was clearly observed that there was precipitation in the polar regions.
