| 摘 要： | 对原产贵州的14个居群、共7个种的淫羊藿属植物进行配对杂交及其结实率统计分析研究。结果显示,该属所有的种类都可以杂交,不同的杂交组合的杂交结实率存在着明显的差异,结实率最低的为15.38%,最高可以达到92.94%;从结实率看,7个种可以明显分成两类:1类,就是E.myrianthum,和另外6个种的结实率均较低,绝大多数在30%以下,2类,包括剩余的6个淫羊藿种,两两之间的杂交结实率较高。研究结果对该属植物进一步的品种培育研究提供了一定参考,同时也为该属植物的系统进化研究提供了一定的资料。

| Abstract: | The crossability of seven species belonging to genus Epimedium native to Guizhou,China were studied in the aspect of seeding ratios of hybridization.Results showed the hybridizations of any combination among these seven species are all successful,and there are obvious differences among seeding ratios of combinations,for the highest is up to 92.94% and the lowest only 15.38%.Based on data of seeding ratios,seven species studied can be dividedinto two groups: Group one is only one species,E.myrianthum,with lo... |
