摘要
为探讨木材构造和木材染色效果之间的相关性变化规律 ,本研究测定了 5株 34块人工林毛白杨的解剖构造及其木材染色效果 ,对二者的相关性进行了多元回归分析。结果表明 ,毛白杨木材的染色效果与解剖因子之间有一定的相关关系 ,各染色效果指标与木材解剖因子间的复相关系数在 0 4 836～ 0 7998之间。采用比较多元回归分析标准回归系数的方法 ,确定出影响毛白杨木材染色效果的主要解剖因子为导管比量、木纤维比量和木射线比量等因子。
To look for the relationship between wood structures and wood dyeing effects is a more important research field developed in recent years. Eleven parameters of wood structure and their wood dyeing effects for 34 pieces of sample panel from 5 trees of Chinese white poplar from plantation were examined based on the data to carry on the multiple regression analysis. The regression results show that each variable of wood dyeing effects has higher relationship with the wood structures, and the multiple correlation coefficients between each variable of wood effects and wood structures are 0.4836～0.7998; the main factors of wood structures influencing wood dyeing of Chinese white poplar are proportion of wood ray, proportion of vessel and proportion of wood fiber according to comparing the standardized regression coefficients of multiple regression equation.
