摘  要：
【目的】筛选出适宜新疆乃至西北地区造林的优良杨树无性系。【方法】以银白杨×新疆杨杂交的8个无性系为研究对象,在新疆北屯、玛纳斯和伊犁实验区进行区组设计,监测每年的胸径、树高,对生长指标进行分析。【结果】8个无性系在三个试验区间的生长差异明显,8个无性系的高生长量明显大于径生长量,且树高和胸径生长量之间存在极显著的正相关关系;8个无性系材积增加量在三个试验区间的差异显著。其中,北屯试验区108无性系的材积增加最大,为0.774 4 m3,527和184无性系次之,分别为0.725 5和0.667 7m3;玛纳斯试验区内536、108和389无性系的材积增长量分别为0.271 0、0.243 2和0.183 0 m3;伊犁试验区内8个无性系的材积增长量为0.269 5～0.336 6 m3,差异不显著。【结论】在单一的生长表现上,108、184、527、536无性系的高径生长优于其他无性系,其中,108无性系表现突出,是可以进行推广的优良无性系。

摘  要：
【Objective】This project aims to select superior poplar clones suitable for Xinjiang and northwest of China.【Method】Eight hybrid clones from Populus alba and Populus were studied in Xinjiang Beitun,Manas,and Yili.Block design was used in experimental plots to monitor the annual DBH and tree height.The growth index was analyzed with SPSS.【Result】There are significant growth differences among 8 hybrid clones in three experimental plots.The height growth of 8 clones was significantly greater than the diameter growth and there are highly significant positive correlation between the height growth and the diameter growth.The difference among the increasing amount of volume of eight hybrid clones was statistically significant in three regions.The increasing amount of volume of 108 is biggest in Beitun and it is 0.774 4 m3,the 527,184 take the second place,and they are 0.725 5 m3 and 0.667 7 m3.In Manasi,the increasing amount of volume of 536,108 and 389 hybrid clones are 0.271 0 m3,0.243 2 m3 and 0.183 0 m3 respectively.Whereas the increasing amount of volume of eight hybrid clones varied from 0.269 5 m3 and 0.336 6 m3.The differences are not obvious.【Conclusion】From the perspective of growth performance,the height growth and diameter growth of 108,184,527 and 536 is greater than those of the other clones,and 108 has outstanding performance,which is good to be promoted.
