Treatability and decay resistance of Acacia mangium.

摘要

The decay resistance of the outer heartwood of untreated Acacia mangium from two sources was evaluated against the white-rot fungus Coriolus versicolor, the brown-rot fungus Gloeophyllum trabeum and the subterranean termite Reticulitermes flavipes. Acacia mangium heartwood from Sedili was found to be slightly resistant and heartwood from Kemasul was determined to be moderately resistant. Acacia mangium treated to different retentions with copper-chromate-arsenate (CCA) also was evaluated against the two rot fungi and termites. No decay by either G. trabeum or C. versicolor occurred at CCA retention greater than 0.3 pcf. The study indicated a variation in both the decay resistance and treatability of A. mangium from the two sources.
