| 摘 要： | 报道了唐古特大黄(Rheum tanguticum)5个居群的染色体数目和核型,结果如下:大武、柯曲、达卡三个居群均为2n=2x=22=2sm 20m;吉卡居群为2n=2x=22=20m 2M;松潘居群为2n=2x=22=2sm 18m 2M。大武,柯曲和吉卡居群核型类型属于1A型,达卡和松潘居群属于2A型。Q型聚类分析结果表明,5个居群在核型上存在一定分化,这可能是由不同的生境造成的。 |
| 关 键 词： | 唐古特大黄 核型 Q型聚类分析 |

| Abstract: | The chromosome numbers and karyotypes of Rheum tanguticum in 5 populations were firstly reported in this paper.The results are as follows:karyotype formulae of DW,KQ and DK populations are all 2n=2x=22=2sm 20m;JK population is 2n=2x=22=20m 2M;SP population is 2n=2x=22=2sm 18m 2M.The karyotypes of DW,KQ and JK populations belong to 1A type while DK and SP populations belong to 2A type.The result of Q cluster analysis of five populations shows that the karyotypes of 5 populations differentiate in some degree,which may be caused by different habitats. |
