摘 要：对分布于中国西北地区的3种黄耆属植物进行了细胞学研究，核型研究结果表明，3种黄芪属植物均为二倍体。3个种的染色体数目和核型公式分别为：单叶黄耆（A. efoliolatus）2n=16=12m（2SAT）+4sm，“1A”核型；太原黄耆（A. taiyuanensis）2n=16=14m（2SAT）+2sm，“1A”核型；变异黄耆（A. variabilis）2n=16=4m+10sm（2SAT）+2st，“3A”核型。除变异黄芪的染色体数目和核型有过报道外，其余2种的染色体数目及核型均为首次报道。

Studies on cytology of 3 Astragalus species from Northwestern China
Abstract: The chromosome numbers and karyotypes of three Astragalus species from northwestern China are reported in this paper. The results of karyotype research show that all 3 species are diploid. Their chromosome numbers and karyotypes are formulated as follows: A. efoliolatus, 2n=16=12m(2SAT)+4sm, “1A” type; A. taiyuanensis, 2n=16=14m(2SAT)+2sm, “1A” type; A. variabilis, 2n=16=4m+10sm (2SAT)+2st, “3A” type; The chromosome numbers and karyotypes of all the 3 species are reported for the first time except A. variabilis.
Key words: Astragalus, chromosome number, karyotype, Northwestern China
