摘要
以2个品系人工林杨树木材[欧美杨无性系72杨(Populuseuramericanacv.I-72/58)和69杨(P.deltoidescv.I-69/55)]为对象,分析人工林杨树心材和边材pH值和缓冲容量及化学成分含量之间的差异。结果表明,除了聚戊糖差异显著外,72和69杨树株间心材和边材的化学成分含量差异不大;72和69杨株间心材和边材的pH值和酸碱缓冲容量的差异不显著;72杨和69杨心边材化学成分含量差异并不显著,但是72杨和69杨边材木素差异显著;72杨和69杨心边材pH值和酸碱缓冲容量的差异不显著。
Two kinds of poplar clones wood, poplar 72 (Populus euramericana cv.I-72/58) and poplar 69(P.deltoides cv.I-69/55) were selected as the materials. It was analysed that the difference between heartwood and sapwood about the content of chemical components,pH value and buffer content from the plantation poplars.The results showed that:There were no obvious difference between heartwood and sapwood about the content of chemical components in poplar 72 and poplar 69 except pentosan.There were also no obvious difference between heartwood and sapwood about pH value and buffer content in poplar 72 and poplar 69.There were no obvious difference between heartwood and sapwood about the content of chemical components in poplar 72 and poplar 69, except lignin in sapwood.There were no obvious difference between heartwood and sapwood about pH value and buffer content in poplar 72 and poplar 69.
