摘要
对引种日本落叶松8个无性系自由授粉子代测定林树高和胸径进行调查和分析,在α=0.05和α=0.01的显著性水平上进行差异性测验,结果不同家系间的树高和胸径差异极显著,且家系与试验区组对树高存在显著的交互作用;参试家系树高单株遗传力为0.841 4,家系遗传力为0.597 7,胸径单株遗传力为0.431 4,家系遗传力为0.592 0.
The height and diameter at breast height of 8 clone progeny test forest of free pollination from Larrix Kaempfri（lamb.）Carr.were investigated and analyzed.On the significant levels（α=0.05;α=0.01）,the tree height and diameter of different pedigrees differ significantly.The individual heritability in height is 0.841 4 and the family heritability is 0.597 7;the individnal heritability in DBH is 0.4314 and the family heritability is 0.592 0.
