Monitoring of pollen micromorphology of Acanthophyllum C. A. Mey. (Caryophyllaceae) genus from central anatolian in Turkey

Abstract

Pollen morphology of Acanthophyllum C. A. Mey(Caryophyllaceae) species in Turkey were investigated by light and scanning electron microscopy in this study. There are 5 species in Turkey belonging this genus: Acanthophyllum mucronatum C. A. Meyer, Acanthophyllum acerosum Sons., Acanthophyllum microcephalum Boiss., Acanthophyllum oppositiflorum Aytaç, Acanthophyllum verticillatum (Willd.) Hand.-Mazz. The pollen grains of Acanthophyllum species are radially symmetrical and isopolar, oblate-spheroidal and prolate-spheroidal, operculate, and pantoporate, their pores have conical spinules on operculum. Pore numbers and diameter, exine thickness, pollen ornamentation and operculum ornamentationvary between Acanthophyllum species. © 2017 Elsevier B.V., All rights reserved.
