摘　　要：采取非破坏性取样法对油松不同家系木材管胞形态的比较研究与分析结果表明：油松子代测定林的木材管胞长度长，长宽比大，柔性系数高，是良好的纤维工业原料；家系间管胞长度变化大，家系内管胞长度差异显著。Morphological comparison of the wood tracheid of every family was conducted by sampling undestructively. The results are as follows. The tracheid is long in length, great in tracheid length-width ratio and tracheid lumen-diameter in these families, so it is a good raw material, better in breeding because of the obvious variation in tracheid length among these families and within some families.
