Studies on the durability of Acacia hybrid woods through environmental friendly oil-heat treatment process

The durability of oil-heat treated Acacia hybrid wood, an important plantation species in Sabah, was tested using in-vitro techniques against three different wood decay fungi (P. sanguineus,C . versicolor and G. trabeum).T o determine the effectiveness of the treatments , 900 wood blocks of Acac...
