Anatomical, Palynological and Seed Surface Characteristics of Aethionema sancakense Yıld. & Kılıc (Brassicaceae)

Abstract

In this study, Aethionema sancakense Yıld. & Kılıç (Brassicaceae) anatomical, palynological and seed surface features were determined. This study aims to reveal the structural features of this species. Root, stem cross-sections, leaf epidermis features were investigated from the plant and anatomical features were determined by taking images. Superficial and transverse sections were taken from the plant by hand, stained with alcian blue and safranin at a ratio of 3:2, examined under a light microscope and photographed. Multi layered cortex structure was detected under the outermost epidermis of the trunk. Peridermis layer is torn in some points and removed from the root. The cortex layer is composed of parenchymal cells and is in 7-8 rows. The sclerenchymal tissue in the cortex layer consists of 2-4 rows of cells arranged intermittently. For palynological examinations, pollen of A. sancakense were examined under the light microscope by Woodhouse method. The type of pollen, whose electron microscope images were taken, was determined as monad and aperture type tricolpat. It was observed that the pollen grains were radially symmetrical and isopolar and their measurements were taken. The seed surface was dark brown and oval shaped, and the surface ornamentation was reticulate-verrucate. In our study, we tried to determine the taxonomic characters of A. sancakense in terms of both anatomical characters and palynological features.
