以天然林五角槭的木材解剖性质为研究对象,分析其株内木材材质径向变异规律,对幼龄材与成熟材进行初步界定。结果表明:细胞壁厚、壁腔比、胞壁率和径、弦向直径幼龄期波动较大,成熟期波动减弱;木纤维长度符合Pan.shinⅠ模型,幼龄材拟合度较好;组织比量符合Y=acebx变异模型;幼龄材和成熟材的界定年限为28~33a之间。

Taking wood anatomical property, of A. mono Maxim natural forest as research object, its radial variation rules of wood properties was analyzed, which could give an initial confirmation of the boundary between juvenile wood and mature wood. Results show that the fiber wall thickness, cell wall to cavity ratio, fiber wall ratio, radial diameter and tangential diameter of juvenile wood have greater fluctuate than that of mature wood. Wood fiber length belongs to Panshin I Pattern with a high fitting degree in juvenile wood. Tissues radio satisfies the model of y = aebx. The boundary area of juvenile wood and mature wood is between 28a to 33a.
