| 摘 要： | 以人工林班克松的木材解剖性质为研究对象，分析研究其株内木材材质径向变异模式，对其幼龄材和成熟材进行初步界定。结果表明：早材管胞径弦向直径和晚材胞壁率的变化符合PashinⅠ模型，早材胞壁率的变化符合PanshinⅢ模型；回归分析中早材拟合度较晚材好；幼龄材和成熟材的初步界定年限为9-11a。

| Abstract: | Taking radial variation of wood properties of Pin,us banksiana plantation as research object, its variation mode within strain was analyzed, and the boundary of juvenile wood and mature wood was preliminarily confirmed. Results show that the tracheid radial and tangential diameter of spring wood and tracheid wall percentage of late wood are in line with Panshin I model, while tracheid wall percentage of spring wood belongs to Panshin Ⅲ pattern. The spring wood has better fitting degree than late wood in the regression analyzing. And the defined period of boundary between juvenile wood and mature wood is 9a-11a. |
