摘　　要：为做到适材适用、全面提高棕榈藤材的高附加值加工利用水平,以高地钩叶藤与大钩叶藤为研究对象,在径向与轴向对两种藤材纤维的特性进行统计分析。结果显示:高地钩叶藤与大钩叶藤纤维的长度、直径、腔径、双壁厚分别为2007.51μm与2016.02μm、18.11μm与20.46μm、10.62μm与8.84μm、7.49μm与11.61μm。径向自外向内,高地钩叶藤纤维长度和宽度先增后降;大钩叶藤纤维宽度、双壁厚和高地钩叶藤纤维长宽比先降后增;大钩叶藤纤维长度、长宽比和两藤纤维壁腔比逐渐下降;高地钩叶藤纤维双壁厚和两藤腔径、腔径比逐渐上升;两种藤纤维腔径经F检验在0.01水平上差异极显著。轴向自下向上,高地钩叶藤和大钩叶藤的纤维长度分别呈降-增-降和增-降-增变化趋势;高地钩叶藤纤维长宽比先增后降;两藤纤维腔径、腔径比和大钩叶藤纤维长宽比逐渐上升;两藤纤维宽度、双壁厚和壁腔比逐渐下降;两种藤纤维长度和腔径经F检验在0.01水平上差异极显著。In order to adapt to the application,and to improve the level of high value-added processing and utilization of rattan material,Plectocomia himalayana and P. assamica were chosen as the object,and the fiber characteristics of them in radial and axial directions were counted and analyzed. The length,diameter,lumen diameter,double wall thickness,lengthwidth ratio,wall-lumen ratio and lumen-width ratio of P. himalayana and P. assamica were,respectively,2 007. 51 and2 016.02,18.11 and 20.46,10.62 and 8.85,and 7.49 and 11.61. From outside to inside in radial direction,the length and diameter of fiber of P. himalayana increased firstly and then decreased. The diameter and double wall thickness of P.assamica and length-width ratio of P. himalayana decreased firstly and then increased. The length and length-width ratio of P. assamica and wall-lumen ratio of P. himalayana and P. assamica decreased gradually. The double wall thickness of P.himalayana and cavity diameter and lumen-width ratio of P. himalayana and P. assamica increased gradually. The cavity diameter of them was significantly different by the F-test at 0.01 level. From bottom to top in axial direction,the length of the fiber of P. himalayana and P. assamica were drop-rise-drop and rise-drop-rise,respectively. The length-width ratio of fiber of P. himalayana increased firstly and then decreased. The lumen diameter and lumen-width ratio of P. himalayana and P. assamica and the length-width ratio of P. assamica increased gradually. The diameter,double-wall thickness and wall-lumen ratio of fiber of P. himalayana and P. assamica decreased gradually. The fiber length and cavity diameter of them were significantly different by the F-test at 0.01 level.
