Abstract

Chromosome numbers and the karyotypes of 3 Saussurea species are studied in the eastern edge of Qinghai-Tibeten Plateau.The chromosome numbers and the karyotypes were as follows: karyotype of S.kansuensis was diploid(2n=2x=32=12m+16sm+4st) and belongs to stebbings 2B type;karyotype of S.macrota was diploid(2n=2x=26=10m+14sm+2st) and belongs to stebbings 2A type;karyotype of S.undulata was diploid(2n=2x=26=6m+20sm) and belongs to stebbings 2B type.No satellites and B chromosomes have been found in these 3 species.
