种源内木材气干密度、力学强度及胞壁率差异不显著，管胞长、宽和壁厚的差异均显著且高于种源间的差异。

Meanwhile, there were not significant differences in wood air dry density, mechanical strength and cell wall percentage of intra provenance.

两种木材的力学性质与气干密度表现为显著的正相关关系。

There was a remarkable positive correlation between mechanical properties and air-dried density for two wood species.
