Chromosome Counts of Some Doronicum (Asteraceae: Senecioneae) Taxa from Turkey

Abstract

In the present study, mitotic chromosome numbers of nine taxa of Doronicum (Asteraceae) from the northeast Anatolia, four of which are endemic to Turkey, were counted. The chromosome counts of D. balansae, D. bithynicum subsp. bithynicum, D. dolichotrichum, D. macrolepis, D. maximum, and D. tobeyi were reported in this research for the first time. Somatic chromosome numbers were counted using squash preparations obtained from active root tips. All the investigated taxa have been proven to be diploid (2n=60). This research, consistent with the previously reported chromosome counts of the members of Doronicum, has contributed to chromosome number data of the genus.
