摘　　要：为更好地了解棕榈藤材性能、提高我国棕榈藤材高附加值和加工利用水平,选择高地钩叶藤为对象,采用显微图像分析系统,对该藤2 m处的节间和节部的纤维形态特征及组织比量进行了统计与分析。结果表明,节间与节部纤维的长度、宽度、腔径、双壁厚、长宽比、径腔比、壁腔比的平均值分别为2 154.50μm和1 573.22μm、17.34μm和18.11μm、1.48μm和5.33μm、6.98μm和7.78μm、124.51和86.69、2.30和2.48、2.33和2.59;节间和节部的纤维、筛管、导管、薄壁细胞组织比量的平均值分别为8.89%和10.77%、4.50%和4.78%、12.09%和12.67%、74.52%和71.81%。经F检验,节间与节部的纤维长度、双壁厚、长宽比、壁腔比在显著性水平0.01下差异极显著,而纤维径腔比在0.05水平上差异显著,节间的纤维形态特征优于节部。In order to understand the performance of rattan materials, to improve the high value-added and levels of processing & utilization for Chinese rattan resources, Plectocomia himalayana was chosen as the research object in this paper.The fiber morphological characteristics and tissue proportion of internode and node at 2 m were analyzed by using microscopic image analysis system.The average fiber length, width, lumen diameter, double wall thickness, length-width ratio, width-lumen ratio and double wall-lumen ratio of internode & node were 2 154.50&1 573.22 μm, 17.34&18.11 μm, 1.48&5.33 μm, 6.98&7.78 μm, 124.51&86.69,2.30&2.48,2.33&2.59,respectively.The fiber proportion, sieve tube proportion, vessel proportion, parenchyma proportion of internode&node were 8.89%&10.77%,4.50%&4.78%,12.09%&12.67%,74.52%&71.81%,respectively.The F-test at 0.01 level indicated that the fiber length, double wall thickness, length-width ratio and double wall-lumen ratio were significant different between internode and node.,and the fiber width-lumen ratio was different between internode and node.The fiber morphological characteristics of internodes was better than those of nodes.
