| Abstract: | Through analyzing and evaluating the growth and stability of seven clones of Populus L. with preserving rate more than 70 percent, the results show that Zhelin No. 4 and Bailin No. 2 have higher stress resistance and growth. The growth of diameter for 8 - year young tree can reach to 12.8 cm and 11.6 cm, which is 124 percent and 116 percent of the control. The tree height for 8 - year young tree can reach to 11.7 m and 12. 1 m, which is 129 percent and 133 percent of the control. Zhelin No. 4 and Bailin No. 2 are comprehensively evaluated as fine clones. |
