| 摘 要： | 测量了不同海拔、树龄的杉木人工林的管胞形态特征,并初步研究了管胞长度与年轮宽度、晚材率、木材密度以及有关力学强度(顺纹抗压、抗弯强度)的相互关系。可利用管胞形态(长度、直径、胞壁厚度)区分成、幼龄材的界限范围。

| Abstract: | This article provides the properties of tracheid shape of planted forest with age in different elevation. The preliminary study is also made on the tracheid length, the width of ring, the late-wood percentage, the density and the direct and indirect correlation concerning mechanical strength (crushing strength along the grain and bending strength). Meanwhile, the tracheid shape (length, diameter ect.) is put to use in distinguishing juvenile wood from mature wood. |
