摘要
对初选出的7个杨树无性系在豫南3个区试点的形态特征、生长特性和速生性进行了试验对比。结果表明:不同无性系在抗逆性、形态特征、生长特性和速生性方面存在显著差异。表现最好的无性系是TZ-8、其次是TZ-5和TZ-6,7a生平均材积分别为0.6093、0.5329m3和0.5149m3,与对照相比,增益分别为264%、231%和223%。
Area experiments were conducted to study the morphological properties and fast-growing characteristics of 7 primarily selected poplar clones in the three experimental sites across the southern areas of He＇nan. The results indicated that the differences were obviously exited in morphological properties, fast-growing characteristic, and resitance among the poplar clones. Comprehensively, the best clone was TZ- 8, and the clones TZ- 5 and TZ - 6 were also better than the others. The average individual volume of timber of 7 years old plantation for TZ -8, TZ - 5, and TZ -6 were 0. 609 3 m3 ,0. 532 9 m^3 and 0.514 9 m^3 , and increased by 264%-231% and 223%, respectively, compared with the control.
