真菌侵蚀前后泡桐材化学成分变化剖析

Change of the Chemical components of Paulownia Wood before and after Fungi Rotting

简述了真菌致泡桐材变色原因及机理。对真菌侵蚀前后泡桐材化学成分进行的分析．结果表明：真菌侵蚀后泡桐材抽提物含量有不同程度的增加、木质素含量相对增加，综纤维素、戊聚糖含量明显降低；并对其产生变化的原因进行了剖析。

The reason and mechanism of paulownia stain are briefly introduced in this paper. and the chemical components of paulownia (Paulownia elongata) wood are analyzed before and after fungi rotting. The results show that the substances extracted from invaded paulownia wood after fungi erosion are increased with different level. lignin amount is relatively heightened, multiple cellulose and pentosan are obviously declined, and the reasons for variation of component are also discussed.
