| 摘 要： | 对89个黑杨无性系进行苗期试验测定，结果表明，大多数黑杨无性系适合在河南地区栽植，造林当年多数成活率在80％以上，不同无性系之间胸径和树高生长差异极显著，具有明显的遗传变异，遗传变异系数分别为10．16％，8．57％，对胸径和苗高的生长进行多重比较，选出79－35，79－38两个优良无性系。

| Abstract: | Nursery testing of 89 Aigeiros clones is conducted Results show thatmost of the clones are suitable for Henan zone,and current survival rate is above 80% The difference of growth among clones is significant, and genetic variation is very evident, coefficient of genetic variation is 10 16%,8 57%,respectively The clones of 79-35 and 79-38 are selected by multiple comparisons of diameter and height. |
