滇西北玉龙雪山两种野生观赏植物的核型分析
- Title:
- Karyotype Analysis of Two Wild Ornamental Plants in Yulong Mountains，Northwest Yunnan
- 文献标志码:
- A
- 摘要:
- 以玉龙雪山2种野生观赏植物胀萼蓝钟花和总花蓝钟花为试材，进行了核型分析。结果表明：胀萼蓝钟花为四倍体，核型公式为2n=4x=24=2M+18m+8sm，总花蓝钟花为二倍体，核型公式为2n=2x=12=6m+6sm，2种植物的核型均为2B型，核型数据均为该区域的首次报道。
- Abstract:
- Taking Cyananthus inflatus and C.argenteus which were wild ornamental plants in Yulong Mountains as metarials，karyomorphological studies were conducted.The result showed that C.inflatus was tetraploid and C.argenteus was diploid.The karyotype of C.inflatus 2n=4x=24=2M+18m+8sm，C.argenteus 2n=2x=12=6m+6sm，and the karyotype asymmetry of the two species was 2B.Cytological data were reported firstly in the region of two species.
