摘　　要：Tracheid characteristics ofPicea koraiensis from natural stand in Liangshui area and plantation in Mao'ershan area were studied. The results of variance analysis showed that the tracheid length, diameter, and thickness of tracheid wall were significant differences between the growth rings. All those characteristics tend to increase from heart-center to bark. In natural stand, it has positive correlation between the characteristics. In plantation, the tracheid length has positive correlation with the trachied diameter, while both the trachied length and the trachied diameter has negative correlation with the thickness of trachied wall. The tracheid length and diameter have no significant difference in growth between natural stand and plantations. The thickness of tracheid wall from the plantation is a little thicker than that from the natural stand before 15 years.本文分别对凉水地区的红皮云杉天然林和帽耳山地区的红皮云杉人工林的管胞性状进行了研究，方差分析结果表明：管胞长度、管胞直径和管胞壁厚度在各年轮间都存在显著差异。管胞的性状从隋心到树皮都呈现出增加的趋势；天然林中，管胞各性状间存在显著的正相关；人工林中，管胞长度和管胞直径呈明显的正相关，但管胞长度和管胞直径分别与管胞壁厚度存在显著的负相关关系。天然林和人工林相比，管胞长度和管胞直径都没有太大差异，只是在15年生以前，人工林的管胞壁厚度稍大于天然林。
