POLLEN MORPHOLOGY OF SILENE L. (CARYOPHYLLACEAE) FROM TURKEY KEMAL YILDIZ
Abstract: Morphology of pollen grains of 13 species (3 of which are endemics
in Turkey) belonging to nine sections of the genus Silene L.,
(Caryophyllaceae), collected from Northwest Anatolia in Turkey,
was investigated using light, scanning electron (SEM) and projectina
screen scale microscopy. The pollen grains were pantoporate, spheroidal
and semitectate with perforations, spinulose exine. S. rhynchocarpa
Boiss., with highest number and S. otites (L.) Wibel with lowest number
of pores have the right taxonomical positions. The taxonomical position
of S. compacta Fischer and S. dichotoma Ehrh. subsp. sibthorpiana
(Reichb) Reich., which have flowers forming heads and are monochasial
is disputed because they have lower pore number in relation to the other
taxa, although they have other phylogenetically advanced characteristics.
