| Abstract: | In this paper,the chromosome numbers and the karyotypes of Aster poliothamnus in the Eastern of Qinghai-Tibet Plateau were studied. The result showed that the chromosome numbers was 2n=32(diploid). The karyotype formulae was 2n=2x= 32=26sm+6st, karyotype belonged to stebbings 4A type. No satellites had been found. |
