摘　　要：对华北驼绒藜、驼绒藜和内蒙古驼绒藜染色体进行了研究。结果表明,3个种的染色体基数均为9,华北驼绒藜为二倍体,驼绒藜为四倍体,内蒙古驼绒藜为六倍体。这3种植物即使在同种植物内常因产地不同其核型也有差异。Studies on chromosome of C. arborescens,Ceratoides latens and Ceratoides intramongolica showed that the basic chromosome number of three Ceratoides spp. were all 9 C. arborescens was diploid,Ceratoides latens was tetrap]oid,and Ceratoides intrarnongolica was hexaploid. These three plants ,even within the same species ,often presents different karyotypes because of different origin
