Data on the palynomorphological characterstic of the genus Silene from Albania


The palynomorphological features of four species belonging to the genus Silene (Silene italica, Silene armeria, Silene pusilla and Silene fabarioides) from different regions of Albania, were investigated and studied by light microscope. This study aims to assess and highlight the existence of significant differences in pollen size, distance between two pores, the exine sculpture and pores number found in these species. Pollen grains were usually radially symmetrical, polar, polypantoporate, spheroidal. The pores were circular contours, operculate which due to thickening of intine in this zone, come out like a cupole. The number of pores varied from 20 to 26 in Silene italica, from 16 to 20 pores in Silene fabarioides and Silene armeria, and from 12 to 16 pores in Silene pusilla. The ornamentations of exine varied from microechinate to microperforate (punctate) at Silene italica, Silene fabarioides and Silene pusilla, whereas at Silene armeria the sculpure of exine was reticulate. The biggest pollen grains were found in Silene fabarioides, whereas the smallest ones were found in Silene armeria.
