Abstract:

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.
