| 摘 要： | 腐朽是木材最严重的生物破坏,它能引起木材结构损坏,造成经济上的巨大损失.白桦(Betula platyphylla)是极易腐朽的树种(李坚,2002).本文利用5种木材腐朽菌对白桦进行生物降解,根据质量损失率筛选出易腐和抗腐植株,进一步研究易腐和抗腐白桦总酚含量的差异与木材腐朽抗性的关系.为今后在林木遗传改良中筛选适宜的天然抗腐朽植株提供理论基础,同时也为森林培育、木材利用等方面的研究提供相关信息,减少防腐剂的使用,降低防腐剂对环境的污染.

| Abstract: | Five wood rot fungi were used to decay 300 mature trees of white birch ( Betula platyphylla ) in Liangshui experiment stations. The decaying susceptible and resistant populations in 10 trees each with the highest and lowest weight loss were selected, in which total phenol in wood was tested. The result showed that the birch wood with lower total phenol was easy to be decayed by Forms fomentarius and Piptoporus betulinus; Irpex lacteus, Pholiota adiposa and Coriolus versicolor were not sensitive to total phenol in white birch wood. After GC-MS test to methanol extractionof white birch wood, 6 organic compounds were found. This paper would provide some useful information in future study difference in the chemical characteristics of the wood between decaying susceptible and resistant populations, and select natural anti-decadent plants. |
