真菌侵染对泡桐材微观结构及主要组分的影响

The Effect of Stain Fungus on the Micro-structure and Main Constituents of Paulownia Wood

进行了变色真菌对泡桐木材微观构造及主要组分的影响研究．作了链格孢菌（ Ａｌｔｅｒｎａｒｉａ ａｌｔｅｒｎａｔａ）侵染泡桐木材试验、检测了真菌对泡桐木材的侵染状况、并确定了真菌侵蚀泡桐木材的主要部位．测试了泡桐木材在真菌作用下的成分变化、阐明了真菌导致泡桐木材发生变色的物理化学过程。

The effect of stain fungus on the micro-structure and tile 'lain constituents of paulownia (Paulownia elongata) was studied in this paper. The test of paulownia wood infected by stain fungus (Alternaria alternata) was done and the erosion induced by the fungus to paulownia wood was inspected. Meanwhile the distribution of fungus invading paulownia wood was ascertained. the component clliinge of paulownia wood stained by tile t'ungus was analyzed. and the physical and chemical procedure that stain occurred due to the action of fungus was also stated.
