Özet
A comparative palynological study of 22 taxa (9 of which are endemic) of the genus Arabis L. (Brassicaceae), belonging to six sections, was conducted with acetolyzed and non-acetolyzed pollen grains using light microscopy (LM) and scanning electron microscopy (SEM). Descriptions of pollen, LM and SEM were provided. All pollen grain shapes of said species were separately calculated. Total pollen shape of Arabis is mostly oblate-spheroidal (43.09 %), but also contains prolate-spheroidal (23.27 %), subprolate (22.04 %), suboblate (6.54 %), prolate (4.04 %) and oblate (0.54 %). All pollen grains are tricolpate, but some of them are 2- and 4-colpate. In this study, there are described three pollen morphotypes of Arabis: Alpina type, Nova type, and Hirsuta type. The systematic potentialities oriented to the pollen data of the taxa studied at various systematic levels are also discussed.
