Abstract

In the present paper,
the pollen morphological traits of 4 endemic Silene species: S. duralii, S. ozyurtii, S. anatolica,
and S. salsuginea, were investigated
using light microscopy (LM) and scanning electron microscopy (SEM). The
obtained data were presented for the first time herein. Monad, isopolar, and
spheroidal pollen grains were observed as common characters in all of the
examined species. Pollen shapes among the investigated species were spheroidal,
and the ornamentations were microechinate-perforate. The highest pore numbers
were found in S. salsuginea, while
the lowest pore numbers were in S.
ozyurtii. The interpore distance was greatest in S. anatolica, while it was least in S. salsuginea. As a result of these detailed examinations, the pore
number, interpore distance, shape of the pore and position, and microechinae
number are more significant characters for distinguishing the studied species.
