摘要
本文描述了我国产毛茛科铁线莲属的7个种的染色体数目和形态。其核型公式分别为:芹叶铁线莲和宽芹叶铁线莲为2n(2x)=16=10m+6st(2SAT);黄花铁线莲和棉团铁线莲及山木通为2n(2x)=10m+4st+2t(2SAT);圆锥铁线莲为2n(2x)=32=20m+8st(2SAT)+4t(2SAT);吴兴铁线莲为2n(4x)=32=20m+6st(4SAT)+6t(4SAT);本文还讨论了一些种的分类问题。
This paper deals with chromosomal number and morphology of 7 species of Clematis L. in China. The results are summarized in Table 1. According to the basic number of the genus (x=8), these species can be refered to diploid and tetraploid.
The following Clematis forms are studied cytologically, the chromosome number and the karyotype formula are as follows:
