摘要:

对紫金牛属三种植物进行了核型分析,其中朱砂根染色体数目2n=46、核型2n=46=42m+2sm+2st和紫金牛核型2n=92=58m+24sm+10st为首次报道; 虎舌红核型公式为2n=44=40m+2sm+2st。核型分析结果显示,紫金牛属植物存在染色体数目非整倍体变异及多倍化的进化方式。

关键词: 染色体数目核型朱砂根虎舌红紫金牛

The chromosome numbers 2n=46,karyotype 2n=46=42m+2sm+2st of A.crenata and the karyotype 2n=92=58m+24sm+10st of A.japonica were reported here for the first time. The karyotype formula of A.mamillata were 2n=44=40m+2sm+2st. The karyotype analysis showed that there were aneuploid variation of chromosome number and polyploidization evolution in Ardisia. 1.College of Life Science, Jiujiang University, Jiujiang 332000, China; 2.Lushan Botanical Garden, Chinese Academy of Sciences, Lushan 332900, China)

Abstract:

Karyological stuidies were carried out in three species of Ardisia from China. The chromosome numbers 2n=46,karyotype 2n=46=42m+2sm+2st of A.crenata and the karyotype 2n=92=58m+24sm+10st of A.japonica were reported here for the first time. The karyotype formula of A.mamillata were 2n=44=40m+2sm+2st. The karyotype analysis showed that there were aneuploid variation of chromosome number and polyploidization evolution in Ardisia.
