摘要/Abstract

摘要： 通过对南京地区黑松、马尾松松材线虫病材的化学成分的研究,发展病材的主要化学成分与健康材相比无明显差异,但苯醇抽出物和乙醚抽出物含量却显著减少。病材乙醚抽出物含量的明显减少是松材遭受松材线虫侵袭的特征之一。在乙醚抽出物的组成上病材和健康材也存在差别,此外两者的pH值也不相同,因而可选用适当的指示剂通过显色反应加以区分。

关键词: 松材线虫病木, 化学组成, 乙醚抽出物, 木材pH值, 显色反应

Abstract: Chemical compositions of Pine wilt diseased wood and sound wood have been researched.It was found that there is no notable difference between soundwood and diseased wood in major componentcellulose, hemicellulo and klason lignin,but content of phenealcohol and ethylether extractive substantially decrease.After pine wood is attacked by Bursaphelenchus xylophilus, the decrease in amount of thylethen extractive of diseased wood is a dominant characteristic.Otherwise there are some difference in chemical components of thylethen extractive and PH value of wood between sound wood and diseased wood. The sound wood and diseased wood are distinguished by colour reaction used proper indicator.

Key words: Pine wilt diseased wood, Chemical composition, Ethylether extractive, pH value of wood, Colour reaction
