摘　　要：以6种泡桐的3年生枝条为试验材料,对其木纤维长度、宽度、壁厚、腔径、长宽比及壁腔比的显微镜观测数据进行方差分析、多重比较,结果表明:不同种泡桐木纤维之间差异显著,其中兰考泡桐木纤维最长,95—02与南方泡桐木纤维最宽,95—02与毛×白33木纤维壁最厚,毛泡桐木纤维腔径最小,兰考泡桐木纤维长宽比最大,毛泡桐壁腔比最大。这些木纤维特征决定了它们不同的应用价值。The length, width, wall thickness, lumen diameter, the ratio of length to width, and the ratio of wall to lumen of the branch wood fiber of six paulownia species were analysed. Variance analysis and multiple comparison show notable variations between the wood fibers of the six paulownia species, namely P. elongate with the longest wood fiber, P. 9502 and P. australis with the widest wood fiber, P. 9502 and Paulownia tomentosa × P. fortunei 33 with the largest wall thickness, P. tomentosa with the lowest lumen diameter, P. elongate has the highest ratio of length to width, and P. tomentosa with the highest ratio of wall to lumen. Their applications depend upon their different characteristics of wood fibers.
