对浙江产杉木株内不同高度和圆周不同方位上木材的管胞长度、宽度、长宽比的径向变异模式和木材力学性质与管胞形态的相关关系进行了测定和分析。结果表明：管胞长度、宽度和长宽比的径向变异模式，在株内不同高度和圆周不同方位上大致相似（长宽比在不同方位上除外），管胞形态与年龄呈显著正相关（在０．０１水平）。广义方差分析表明在株内不同高度上，管胞长度、宽度、长宽比差异不显著；在圆周不同方位上长宽比差异显著，其余两项末表现出显著差异；不同年龄间管胞长度、宽度、长宽比均差异显著。在不同高度上，三项力学性质中，只有抗弯强度和管胞长度０．０５水平显著相关，其余相关不显著。
The radial variation pattern of tracheid length, width and aspect ratio of wood in different height and circumference of Zhejiang fir and the correlation between wood mechanical properties and tracheid morphology were measured and analyzed. The results showed that the radial variation patterns of tracheid length, width and aspect ratio were similar in different azimuthal orientations and circumferential directions (except for aspect ratio), and the tracheid morphology was positively correlated with age (At 0.01 level). The generalized ANOVA showed that there was no significant difference in tracheid length, width and aspect ratio at different altitudes in the plant. The aspect ratio in different orientations of the circumference was significantly different, while the other two endings showed significant differences. The length of tracheid , Width, aspect ratio are significant differences. At different heights, only the flexural strength and the tracheid length 0.05 were significantly correlated among the three mechanical properties, while the other correlations were not significant.
