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。
In this paper, we studied the tracheid-like traits of Picea koraiensis plantation and Taipushan plantation in Liangshui area. The results of variance analysis showed that the tracheid length, tracheid diameter, There are significant differences between the years. Tracheid traits tended to increase from Sui to bark. In natural forests, there was a significant positive correlation between tracheids and tracheids. In tracheids, the tracheid length and tracheid diameter showed a significant positive correlation Tracheid length and tracheid diameter and tube wall thickness were significantly negative correlation. Compared with the natural forest, the tracheid length and tracheid diameter are not much different. Only 15 years old, the wall thickness of the plantation wall slightly larger than the natural forest.
