摘要
鱼鳞云杉健康木和被害木干部解剖特征量中,存在显著性差异的指标包括胞壁厚(晚材)、管胞腔直径(径向早材)、管胞直径(早材)、木射线条数、管胞长(早材、晚材)、树脂道比量和木射线比量;逐步回归分析表明,管胞腔直径(径向早材)和管胞长(早材)为正相关,是有利于云杉大黑天牛危害的特征量,树脂道比量、木射线条数和木射线比量为负相关,是对云杉大黑天牛产生抗性的特征量。
The significant difference index of timber anatomical structure between health and inseeted Picea jezoensis include cell wall thickness （ late）, diameter of tracheid cavity, diameter of tracheid, number of xylem ray, length of tracheid （ early and late）, ratio of resin canal and xylem ray. The relationship between anatomical structure of Picea jezoensis and damage by Monochamus urussovi was studied systematically with stepwise regression analysis, from the equation we can see that diameter of tracheid cavity （ early）, and length of tracheid is positive correlation and they are the favorable index of damaged by beetle, and number of xylem ray ratio of resin canal and xylem ray was negative correlation, they are unfavorable index of damaged by beetle.
