| 摘 要： | <正>马尾松木材比重和管胞长度在个体间差异很大,所占分量分别为其群体总变异的40％和20％,因此,通过个体选择可望获得较大的增益。相邻两群体的材性差异不显著,林分选择效果尚待深入研究。不同生长速率的样木间该二性状差异很小。

| Abstract: | Large difference among the individuals of masson pine was found for specific gravity and tracheid, the variations of which were about 40% and 20% of their total population variation respectively. It is important that selection of wood properties was emphasized among individuals. Stand selection seems to be ineffective. No significant difference was also found among tree types with different growth rate for specific gravity and tracheid length. |
