摘要
本文研究了黄芪属(AstragalusL.)植物糙叶黄芪(AstragalusscaberrimusBge.)的染色体。结果显示,染色体数目为2n=16,核型公式K(2n)=2x=16=14m+2sm,染色体相对长度组成为2n=16=8M2+8M1,核型"1A"型。
The number and karyotype of chromosome of Astragalus scaberrimus Bgewere studied in this paperThe results showed that the chromosome number of the species is 2n=16 and its karyotype formula is K(2n)=2x=16=14m+2sm,and the composition of relative length of chromosome is 2n=16=8M2+8M1,belonging to type '1A' of Stebbins karyotype asymmetry
