摘要
对5个不同种源泡桐试材全干密度进行测定、比较和分析,结果表明:不同种源间泡桐木材密度差异显著,其中山东高密楸叶泡桐与湖南湘潭白花泡桐间差异显著,其余品种间均差异极显著;泡桐植株底部、中部和顶部间密度差异极显著;心材与中材间密度差异不显著,而心材与边材间密度差异显著,中材与边材间密度差异极显著。
The oven-dry wood density of 5 provenances of Paulownia tomentosa was determined, compared and analyzed. The results showed that there were significant differences in the wood density among the different prove- nances. The density difference between the Gaomi provenance from Shandong Province and the Xiangtan prove- nance from Henan Province was significant, while the differences among the rest provenances were extremely signif- icant. The study also showed that there were extremely significant differences among the wood samples taken from the base, mid and top parts of the same plant. There was no significant difference between the heartwood and mid- dle wood; there was significant difference between the heartwood and sapwood; whereas there was extremely signifi- cant difference in the wood density between the middle wood and sapwood.
