Abstract:

Four wild populations of Ranunculus japonicus Thunb. from Jiangxi Province were

cytotaxonomically investigated in the work. The common karyotype was found to be

2n=14 = 6m+4sm+4st(2SAT). In a population from Mt. Yunju, in addition to the common

one, two variations were observed, i. e. 2n= 14+1B= 6m+4sm+4st (2SAT)+1B and

2n = 14=6m+6sm(SAT)+2st. Comparing with the common karyotype the variations are the

occurrence of a B-chromosome in one karyotype and the shift of arm ratio of the sixth pair

from “st” to “sm‘ in the other.
