环境和基因型对东北杨树无性系生长性状的影响

树体的表型和适应性受遗传和环境因素的控制。本研究对东北地区3个不同地点(梨树、错海、富锦)营建的40个杨树无性系品比林进行调查分析，方差分析显示，各性状不同变异来源间均存在显著差异(P 小于0.001)。不同性状的表型变异系数变化范围为14.84 %~23.61 %。不同性状的重复性变化范围为0.81到0.97。基因型 × 环境互作模型表明，无性系G33、G38、G32是稳定、高产的无性系，梨树地区是理想的试验环境，可以清晰鉴别无性系间的差异。

The phenotype and adaptability of trees are governed by genetic and environmental factors. In this study, 40 poplar clonal comparative test plantations established at three distinct locations (Lishu, Cuohai, Fujin) in Northeast China were surveyed and analyzed. Analysis of variance revealed significant differences among various sources of variation for all traits (P < 0.001). The phenotypic coefficient of variation for different traits ranged from 14.84% to 23.61%. The repeatability of different traits spanned from 0.81 to 0.97. The genotype × environment interaction model demonstrated that clones G33, G38 and G32 were stable and high-yielding genotypes, while the Lishu area served as an ideal experimental environment that could clearly discriminate differences among clones.
