摘  要:
染色体核型分析表明,膜荚黄芪[Astragalus membranaceus(Fisch.)Bge.]和蒙古黄芪[Astragalus mem-branaceus(Fisch.)Bge.var.mongholicus(Bge.)Hsiao]均为二倍体,2n=2x=16,第8号染色体上均有随体;膜荚黄芪核型为2n=2x=8m(1SAT)+8sm,蒙古黄芪染色体核型为2n=2x=6m+10sm(1SAT);核型对称性分别为2A和2B型。该结果支持《中国植物志》关于蒙古黄芪为膜荚黄芪变种的观点。

摘  要:
Karyotype of Astragalus membranaceus was carried out in this paper.The results showed that A.membranaceus Bge.and A.membranaceus.var.mongholicus(Bge.)Hsiao both were diploid,2n=2x=16,and there was satellite in the 8th chromosome of two Astragalus;karyotype of A.membranaceus Bge.was:2n=2x=8m(1SAT)+6sm+2st,karyotype of A.membranaceus.var.mongholicus(Bge.)Hsiao was: 2n=2x=6m+10sm(1SAT);the karyotype of two Astragalus was belonged to Stebbins' 2A and 2B type respectively,and the opinion of Chinese Flora that A.membranaceus.var.mongholicus(Bge.)Hsiao was the variation of A.membranaceus Bge.was supported.
