Wood anatomy of 12-13 year old Chinese fir plantation in different growth environments (south hillside, mountain valley, ridge, mountain top) was studied by measuring annual ring width, late wood percentage, tracheid length, tracheid width, thickness of cell wall, ratio of length to width, ratio of cell wall to cavity, microfibrillar angle, proportion of wood tissues, air-dried density.
本文采用宏观和微观方法，以木材的年轮宽度及晚材率，管胞形态因子，微纤丝角，组织比量，气干密度为指标，对不同生长环境(南坡，山谷，山脊，山顶)的人工林杉木(12——13年生)的木材解剖特征进行研究，结果表明：(1)不同生长环境全树间的年轮宽度及晚材率均达到了差异显著水平，其大小顺序为，年轮宽度：山谷(7。
4) variance coefficient of latewood percentage
