| Abstract: | Wood properties of six poplar species and varieties of A5-13,A5-17 poplar were analyzed,including the basic density,air-dried density,shrinkage coefficient,fiber length,fiber width,and holocellulose content.The results showed that the A5-13,A5-17 poplar were medium density lumber.The basic densities were both 0.36 g·cm-3 and 0.42 g·cm-3,respectively.The shrinkage coefficients were 0.37 and 0.35,which less than most of poplar species and varieties,indicating higher non-deformability.The fiber lengths were 1 175 μm and 1 230 μm,which were 7.5% and 12.6% longer than that of Populus ussuriensis.The holocellulose contents were 84.3% and 85.4%,indicating the A513,A5-17 poplar were good pulpwood. |
