| 摘 要： | 对20世纪末新引进到辽宁并经初选的12个杨树无性系进行了引种试验研究,通过无性系多点生长对比试验、室内外物候观测、对杨干象抗性评价和材性测试等,筛选出生长快、适应强的杨树新品种中辽1号杨,其材积生长量分别超过当地对照种辽宁杨、沙兰杨、荷兰3930杨和I-214杨14.8%~68.1%。其生长进程中高生长最快期是在5~6年生,连年生长量最大数值达到3.6 m;胸径生长最快期是在3~5年生,连年生长量最大数值达到6.34 cm。而且干型好、材质优良,对杨干象有相对较强的抗性,可作为新品种在其适生区大面积推广。

| Abstract: | Abstract： We carried out a study on the introduction for 12 new clones of poplar introduced to Liaoning at the end of last century and selected preliminarily test. By means of clonal growth testing in different zone, interior and exterior phenological observation, resis- tance evaluation of Cryptorrhynchus lapathi and wood properties testing, filter out fast-growing, adaptable, new poplar variety Populus×canadensis cv.‘zhongliao 1＇ .Its volume growth is respectively more than Populus×Liaoniongends,Populus×canadensis cv. ‘Sacrou 79＇, Populusxcanadensis cv.‘N3930＇from 14.8% to 68.1%.The fastest period in height growth is in 5 ～ 6 year＇ sold, which best current an- nual incremen achieves 3.6 m. The fastest period in DBH growth is in 3 ～ 5 year＇ s old,which best current annual incremen achieves 6.34 cm.It becomes new variety to promote in suitable areas,with mink well,high qualities of wood properties, a relatively strong resis- tance to Cryptorrhynchus lapathi. |
