【摘要】 报道了浙江省常见的２种毛茛属植物──扬子毛茛ＲａｎｕｎｃｕｌｕｓｓｉｅｂｏｌｄｉｉＭｉｑ．和石龙芮ＲａｎｕｎｃｕｌｕｓｓｃｅｌｅｒａｔｕｓＬ．的染色体资料。扬子毛茛体细胞染色体数目２ｎ＝３２，核型组成：Ｋ（２ｎ）＝４ｘ＝３２＝１６ｍ＋８ｓｍ＋８ｓｔ。石龙芮体细胞染色体数目２ｎ＝３２，核型组成：Ｋ（２ｎ）＝４ｘ＝３２＝８ｍ＋２４ｓｍ。更多还原

【Abstract】 The karyotypes and chromosome numbers in the root-tip cells of R. siboldii and R. sceleratus were studied.The chromosome numbers in these species were found to be 2n=32. Their karyotype formulas are presented as follows: R. sieboldii L.K(2n)=4x=32=16m+8sm+8st, R. sceleratus L.,K(2n)=4x=32=8m+24sm.更多还原
