摘　　要：研究 5种不同无性系杂交柳树的纤维形态特征及其径向变异 ,结果表明 :5种杂交柳树 ,纤维长度为 884～ 1 1 2 7μm、纤维宽度为 1 8.63～ 2 3.4 2μm、双壁厚度为 5 .79～ 8.80μm,胞腔径为 1 1 .37～ 1 5 .0 0μm,其沿径向均呈 y=b0 +b1 x+b2 x2The wood properties of five kinds of willows clone (Salix spp.) located at the beaches of Changjing river were studied.The results showed that the wood fiber length were from 884 to 1127 μm,fiber diameter were from 18 63 to 23 43 μm,double wall thinkness were from 5 79 to 8 80 μm,cell cavity diameter were from 11 37 to 15 00 μm.Their radial wood variation could be regressed with y=b 0+b 1x+b 2x 2.
