Karyomorphological studies in seven taxa of the genus Salvia (Lamiaceae) in Turkey

Abstract

In this study, the karyotypes of mitotic chromosomes were determined of seven taxa of Salvia (Lamiaceae) collected from their natural habitats in Turkey: S. viridis (2n = 16), S. candidissima subsp. occidentalis (2n = 20), S. sclarea, S. ceratophylla, S. chionantha (2n = 22), S. viscosa and S. verticillata subsp. amasiaca (2n = 32). The karyotype formulae were 5m+3sm in S. viridis, 2M+5m+3sm in S. candidissima subsp. occidentalis, 1M+10m in S. sclarea, 8m+3sm in S. ceratophylla, 7m+4sm in S. chionantha, 9m+5sm+2st in S. viscosa, and 15m+1sm in S. verticillata subsp. amasiaca by the karyotype image analysis system. Somatic chromosome numbers ranged from 2n = 16 to 2n = 32. The ideograms were drawn based on centromeric index and arranged in decreasing size order. The present results were compared with the previous cytological studies in the genus.
