Karyotype studies on three Ligularia of Changbai Mountain

Abstract

Abstract: Karyotypes of three Ligularia species (L. jaluensis, L. Mongolia, and L. intermedia) from Changbai Mountain were studied using the conventional pressed disc method. The chromosome numbers of the three species were all 2n=58 and the karyotype of L. mongolia was 2A while those of the other two species were 2B. Their indices of karyotypic asymmetry were between 59.22% and 62.89%. Their karyotype formulas were 2n=2x=58=42m+16sm,2n=2x=58=44m+12sm+2st and 2n=2x=58=32m+26sm, respectively. The composition of relative chromosome length was: L. jaluensis - 2n=58=2L+20M₂+30M₁+6S, L. mongolia - 2n=58=28M₂+28M₁+2S, and L. intermedia - 2n=58=2L+28M₂+26M₁+2S. The chromosome numbers and karyotypes of the three Ligularia species tested are reported for the first time.
