| 摘 要： | 试验表明 ,38个 4年生欧美杨无性系间的树高、胸径、年生长量、造林成活率差异均呈极显著水平。用座标综合法评价了各无性系的优劣 ,从中初选出 6个优良无性系 ,其胸径和全高分别比对照高 2 1%和 2 0 %。

| Abstract: | The experiments indicate that there are significant diffrences of tree height?D.B.H?annualD.b.h grouth and plant percentage among 38 four-year old clones of P.X euramericana(Dode) Griniers.We use coordinate-sytnthesixed method to evalrate the advantages and disadvantages of those clones and select six excellent clones whose D.B.H and tree height are 21% ane 20% more than the control group |

| Keywords: | P.X euramericana(Dode) Grinier character difference Excellent clones. |
