摘要:

 对江西九江新公园猫爪草染色体数目的报道进行了改正,发现其染色体数目稳定,为2n=16,因此该种并不象前人所报道的那样是一个多倍体复合体。

Abstract:

This paper corrects the chromosome number of Ranunculus ternatus from Jiujiang New
Park, Jiangxi, reported by Liao et al. in 1991. The chromosome number of this species is found to
be 2n = 16, very stable within the population. The previous report of the tetraploid number of 2n =
32 represents a miscount, which may be caused by overlapping of two metaphase cells.

Key words: Ranunculus ternatus, Chromosome number
