Biology of species Silene bolanthoides Quézel, contandr. & Pamukç. (Caryophyllaceae) which is endemic in Kazdagi (Turkey)

In this study, morphological, anatomical, ecological, palynological, seed germination and caryological features of Silene bolanthoides, which is endemic to Kazdagi, have been studied.Morphological measurements of species were made and some characters were modified. Plant samples for anatomical studies, after pre-processes transferred in to paraffin blocks, 8 µm thick sections were obtained by rotary microtome, stained with aniline-blue & safranine dual staining and anatomical structures were examined at microscope. Physical and chemical analyses of soil samples, which were taken from habitat of the species, soil texture loam, neutral, salt-free, low calcareous, organic matter, phosphorus and potassium were found to be less. In palynological studies, pollen samples have been prepared according to Wodehouse method (1935) and studied under both light microscope and SEM. Pollen shape of S. bolanthoides spheroidal, pollen type periporate, pollen structure tektate and opercula granulated. Percentage of seed germination has been determined %4, both germination and seedling plants growth rates were observed to be slow. At preparations which were obtained from root tips of germinated seeds, chromosome number was determined as 2n=24. Because of the plant with narrow occurrence and low number of individual, the threat category of plant has approved considering as CR B1ab(ii,iii).
