Karyological Studies on Mediterrenean Sage (Salvia aethiopis L.)

Abstract

Mediterranean sage (Salvia aethiopis L.) is a species being part of Lamiaceae family and important in terms of economic aspect. Caryological studies are important in developing this species and determining the hybridizarion process of this species
with other ones. In this study, the root tips obtained after the germination with mature seeds have been pre-treated in the α-monobromonaphtalane solution and stained by aceto-orcein. According to the karyotype analysis applied, it has been observed
that this species has a chromosome number equivalent of 2n=2x=22 (14m + 8 sm). It has been measured that the average length of chromosome regarding to this species is 2.043 µm, the longest arm lenght was 1.994 µm, the shortest arm lenght was 0.604
µm. Relative lenghts of chromosomes ranged between 3.22-6.73%. Arm ratios and centromeric index were changed between 1.140-2.120 and 0.320-0.468, respectively.
