Comparative pollen morphology studies on some species of Brassicaceae in Turkey

Pollen aperture type, shape, size, polar axis length, equatorial P/E ratio, colpus thickness of the sexine and nexine, S/N ornamentation lumen shape width were determined by using light scanning electron microscope. A multivariate analysis was carried out Gover’s general similarity coefficient UPGMA based on 3 qualitative 8 quantitative pollen characters for 43 taxa belonging to 30 genera 19 tribes. In all studied, grains generally small or medium-sized, tricolpate, except in Matthiola longipetala, with an inconspicuous aperture. The varied from prolate-spheroidal perprolate. exine microreticulate, reticulate, macroreticulate. some species, reticulate found together others, macroreticulate ornamentation. It seen that placed near each other dendogram partially supported tribes, such as Brassiceae, Alysseae, Sisymbrieae, Camelineae. is notable closely-related tribes dendrogram, which supports previous molecular studies. addition ornamentation, nexine thickness, length most useful characters. These characteristics can be used identify distinguish genera, species partly within family. They also provide detailed information Brassicaceae taxa, studied herein first time, this knowledge will comparisons future
