| 摘 要： | 研究采用各种处理柱头的方法对胡杨(Populus euphratica)与小叶杨(Populus simonii)之间的杂交障碍进行研究,结果表明,用母本花粉提取液处理柱头的方法最为有效,其成苗率达到了73.68%,在此基础上对F1用回交、测交和自交的方法进行了遗传学分析,F1是真正的杂种,表明远缘杂交取得了成功。

| Abstract: | Study of overcoming distant hybridization barriers between P.euphratica and P.simonii were conducted by using a various treating methods for stigma.Result shows that: using the female pollen extract to treat stigma is most effective,rate of seedling emergence being 73.68%.On this basis,genetic analysis on F1 were conducted by using backcross,measured-cross and self-cross method;it founds that F1 is a real hybrid,and the distant hybridization is successful. |
