摘要
报道了２种细辛属植物——川北细辛（ＡｓａｒｕｍｃｈｉｎｅｎｓｅＦｒａｎｃｈ．）和祁阳细辛（ＡｓａｒｕｍｍａｇｎｉｆｉｃｕｍＴｓｉａｎｇｅｘＣ．Ｙ．ＣｈｅｎｇｅｔＣ．Ｓ．Ｙａｎｇ）的染色体资料．川北细辛体细胞染色体数目２ｎ＝２２，核型公式为Ｋ（２ｎ）＝２ｘ＝４Ｍ＋１４ｍ＋４ｓｍ．祁阳细辛体细胞染色体数目２ｎ＝２４，核型公式为Ｋ（２ｎ）＝２ｘ＝２Ｍ＋２０ｍ＋２ｓｍ．
The number and karyotype of chromosomes of Asarum chinense and Asarum magnificum were studied. The chromosome numbers of A.chinense were found to be 2n=22 and its karyotype formula is K(2n)=2 x =4M+14m+4sm.The chromosome numbers of A.magnificum is 2n=24 and its karyotype formula is K(2n)=2 x =2M+20m+2sm.
