摘    要:利用压片法研究青藏高原东缘两种风毛菊属(Saussurea DC.)植物的染色体数目和核型,结果表明,紫苞雪莲(S.iodostegia)和抱茎风毛菊(S.chingiana)的染色体数目和核型分别为2n=2x=32=18m+14sm,2n=2x=28=24m+2sm+2st.根据Stebbins提出的核型分类原则,这2个种的核型都为2A型.2个种的染色体中均未发现随体.

关 键 词:紫苞雪莲  抱茎风毛菊  核型

Abstract:The chromosome numbers and karyotypes of two species Saussurea DC.are reported by planish method from the eastern Qinghai-Tibetan plateau.The results show that the chromosome numbers and karyotypes of the genus of respectively are 2n=2x=32=18m+14sm,2n=2x=28=24m+2sm+2st.The karyotypes of both species are 2A according to the Stebbins's classification.No satellites are found in these two species.
Keywords:S  iodostegia  S  chingiana  karyotype
