摘 要:
用4种热处理方法处理腺瘤豆心材，可有效去除异味，替代珍贵绿柄桑木材使用。处理后的木材经白腐茵侵染12星期，平均质量损失率与未经处理的试材相比变化不大，天然耐久性等级保持不变，而且其中2种处理方法还能够明显提高木材的耐腐性能，木材的天然耐久性等级因此也由Ⅱ类提高到Ⅰ类。[著者文摘]

Abstract:
The Ghanaian wood dahoma （Piptadeniastrum africanum）, which has been treated with four heat-treatment methods to effectively reduce its unpleasant smell, could be used as an alternative to the precious traditional commercial species iroko （Chlorophora excelsa ）. Following heat treatments, there were few changes in the average weight loss and in the natural durability when the treated wood was subjected to the white-rot fungus Coriolus versicolor for 12 weeks. Furthermore, the decay resistance was increased with two heat-treatments and the natural durability was therefore improved from class 2 to class 1.[著者文摘]
