Karyotype Analysis of Silene salsuginea Hub.-Mor. and Silene doganii A.Duran & Y. Menemen Local Endemic to for Turkey

Abstract

In this study the somatic chromosome numbers and karyotype of two Silene L. species growing naturally in Turkey are examined. These species are Silene salsuginea Hub.-Mor. and Silene doganii A.Duran & Y. Menemen. The somatic chromosome studies were conducted using squash preparation method. The studies revealed that the chromosome numbers of S. salsuginea
and S. doganii are 2n = 24. The basic chromosome number of both species is determined as x = 12. The karyotype formula of S. salsuginea is 11m+1sm and of S. doganii 3m+9sm. The total length of the metaphase chromosomes of S. salsuginea ranges between 1.16 μm-2.65 μm and of S. doganii between 0.88 μm-1.75 μm. The total haploid chromosome length of S. salsuginea is
measured as 20.32 μm, and of S. doganii as 42.08 μm. Their chromosome morphologies, karyogram and ideograms are made using
