摘　　要：以安徽新洲滩地上生长的６９杨为材料，研究季节性淹水对６９杨木材材性及其变异的影响，结果表明，与未淹水相比，长江滩地季节性淹水对６９杨纤维形态特征影响不大，０．０５水平下方差分析检验不显著；对木材微纤丝角，木材密度，木材干缩率和力学性质影响较大，０．０５水平下方差分析检验显著，其中，微纤丝角、基本密度、抗弯弹性模量、抗弯强度和气干体积缩率分别增加了１５．６％、５．９％、１５．７％、１７．２％和２８．５％；而主要解剖特征的径向变异模式基本不受影响。The wood properties of poplar 69 were tested,which was collected from Xingzhou beaches of Changjiang river where seasonal flooding usually takes place.The results showed that seasonal flooding gave a significant effect on poplar 69's wood properties including microfibril angle,basic density,MOE,MOR and air dry volumetric shrinkage with the increase of 15 6%,5 9%,15 7%,17 2% and 28 5% respectively,although its effect on fiber's morphology of poplar 69 was very little.
