香樟干、枝材木射线及导管的研究

Wood ray and vessel of the trunk and branch wood of Cinnamomum camphora Presl

为了充分利用小径材、枝桠材等低等级的木材,对香樟干、枝材木射线、导管进行比较分析。结果发现,干、枝材木射线宽度分别为33.16μm和31.15μm,高度分别为227.49μm和263.84μm,干、枝材木射线形状因子分别为0.152和0.125。在0.05水平上经T-检验,干、枝材的木射线宽度差异不显著,而干、枝材的木射线高度及形状因子差异均显著。干、枝材导管弦向直径平均值分别为84.07μm和86.88μm,属于“略小”级别,在0.05水平上经T-检验,差异不显著。

In order to improve the rational bases for making fully use of the little diameter and branch wood, comparative study about the trunk with the branch of Cinnamomum camphora Presl was conducted by analysing the wood ray, vessel of the trunk ＆ branch wood. The results show that the average width of wood ray of trunk ＆ branch are 33.16 μm and 31.15 μm,while the average height of wood ray of trunk ＆ branch are 227.4 9 μm and 263.84μm, and the shape factor of the wood ray of trunk ＆ branch are 0. 152 and 0. 125 respectively. The diameter of vessel of trunk ＆ branch are 84. 07 μm and 86. 88 μm respectively, belonging to ＂smaller＂ class. The differences of wood ray width and vessel diameter between trunk ＆ branch are not significant at 0. 05 level through T- test, while the differences of wood ray height andshape factor of wood ray between Hem are significant at 0. 05 level through T- test.
