本文以乐昌含笑(Michelia·chapensis)和金叶白兰(M·fovolata)为试材,采用方差分析法分析了两试材构造因子在不同方向和株间的变异;物理性质和强度的株间变异及株内变异。结果表明:木材构造因子的方向、株间变异,物理力学性质的株间变异都非常明显;株内有变异,但株间变异远远大于株内变异。 In this study, Michelia chapensis and M. fovolata were used as experimental materials. The variance analysis was used to analyze the variation of construct factors in different directions and between strains. The correlations between physical properties and intensity Variation and in-plant variation. The results showed that there were obvious variations in the orientation, inter-strain variation and physical-mechanical properties of the wood constructive factors. Variation was found in the strains, but the intra-plant variation was much larger than that in the in-plant variation.
