Abstract
This study explored how simultaneous treatment of monoammonium phosphate (MAP) and boric acid for Pinus densiflora and Populus euramericana influenced the properties such as fire resistance, preservation against Trametes versicolor and Tyromyces palustris, and compressive strength of the treated woods. For specific gravity and compressive strength, the treated woods were higher than the non-treated ones. For the analytical features observed by SEM, the cell walls of the non-treated woods were extremely destructed by T. palustris and T. versicolor while the treated ones relatively remained intact. Especially, P euramericana was more readily exposed to the attack of the rot fungi than P. densiflora.
