Natural durability is the most important quality of wood in use. Manglietia fordiana Oliv. is an indigenous species of high commercial value. Its wood is used as construction material for housing and fine indoor furniture manufacturing in Vietnam. However, there is few information on M. fordiana wood resistance to fungi. In this study, natural resistance of M. fordiana wood against six white-rot fungi was investigated. The results showed that M. fordiana has weak natural
durability. The weight loss was from 11.18% to 27.48% after 2 months of exposure. The highest value was caused by Phanerochaete sordida (27.48%) while the least deterioration level was decayed by Dichomitus squalens (11.18%). Microscopic investigation showed the hyphae were extended over whole wood tissues. It also revealed that P. sordida destroyed lignin, cellulose and hemicellulose.
