摘　　要：对白杨派无性系进行造林试验,通过多性状综合评价筛选出优良无性系。本研究选用41个白杨派无性系苗木在山东省聊城市莘县营建无性系对比试验林,通过测定各无性系8年生胸径、树高、材积、通直度和冠幅,并进行变异分析、方差分析、多重比较和主成分分析,选出综合性状优良的无性系。结果表明,无性系间各性状差异显著,各性状的重复力范围为0.557~0.888。通过对生长和通直度性状进行综合评价,筛选出优良无性系1316、220、2-00、1237、8和1211,其材积分别超过对照LM50杨48.3%、46.1%、27.6%、28.1%、18.8%,且树干较直。其中1316、220和2-00为雄株,不飞絮。这6个优良无性系可以在鲁西黄泛平原区推广应用。Afforestation experiments were carried out on Leuce clones,and excellent clones were selected through comprehensive evaluation of multiple characters.In this study,41 Leuce clones were planted at Shenxian County,Liaocheng city of Shandong province.The diameter at breast height(DBH),tree height,volume,straightness and crown width of each clone were measured in the 8-year old experiment forests.The data were analyzed by variance analysis,multiple comparison and principal component analysis,and the clones with excellent comprehensive characteristics were selected.The results showed that there was a significant differences in each character of the clones.The repeating range was 0.557-0.888 of each character.Through comprehensive evaluation of growth traits and straightness.The five excellent clones were 1316,220,2-00,1237,8 and 1211,with straight trunk.The volume of these clones exceeded the control LM50 poplars by 48.3%,46.1%,27.6%,28.1%and 18.8%,respectively.Among them,1316,220 and 2-O0 were male,seedless.These six excellent clones can be popularized and applied in the Yellow River floodplain of Western Shandong Province.
