摘　　要：本文研究了集约栽培13种5年生白杨无性系木材解剖、纤维品质、细胞次生壁微纤丝角和纤维素相对结晶度、化学成分、木材密度以及制浆等材性。试验结果表明,白杭1、白杭17、白杭10、灵野、新毛、无名等6种无性系的纤维长度变幅为845～917μm;离散系数变幅为0.24～0.28;总纤维比率变幅为62.8％～64.7％;气干密度变幅为0.401～0.519 g/cm^3;化学预处理后得率变幅为87.7％～91.6％;浆张的撕裂指数、耐破指数、抗张指数等性能优于其他无性系,可选为进一步集约栽培品种。Wood anatomy, fibre quality, microfibrillar angle of S2 layer of the secondary wall of the wood cell and the degree of relative crysta-llinity of the wood cellulose, chemical composition, wood density and pulp-making wood properties of 13 5-year-old White Poplar clones in intensive cultivation have been studied. The results show that for the 6 clones:Baihang 1, Baihang 17, Baihang 10, Linye, Xinmao and Wuming,the fibre length range is 845~917μm, the Cv(LN) range o.24~0.28, the total fibre ratio range 62.8 %~64.7 %, air-dried density range 0.41~0.519 g/cm3, the high yield pulp 87.7%~91.6% and the other properties, such as tear index, burst index, tensile index etc., all of which are superior than those of the other clones. The above mentioned 6 poplar clones may be selected for further cultivation.
