摘　　要：对思茅、墨江、镇沅、景谷、宁洱5个种源13年生的思茅松人工林林木干材管胞的形态特征进行了显微观测并对其的差异作了分析研究。结果表明:5个种源间的思茅松人工林其林木干材各年轮的管胞长度、宽度、长宽比在F0.05水平上差异不显著,在种源选择时可不考虑管胞形态特征等因子的影响;从其干材管胞长度和长宽比上看均符合造纸材的要求;种源内和种源间,其林木干材各管胞的形态特征值与年龄都有很好的相关性,由此建立了相应的回归方程,其回归效果较理想。The morphological characteristics of tracheid in timber of Pinus kesiya var. langbianensis of five different provenances including Simao, Mojiang, Zhenyuan, Jinggu and Puer were studied. The results implied that there was no signicant difference on tracheid length, width and length-width ratio of different provenances at 0.05 level. The tracheid morphological characteristics can be ignored during the course of provenance selection. The tracheid length and length-width ratio all meet the requirement of paper wood. The morphological characteristics and tree age are closely related, the regression equation is established and with good effect.
