THE EFFECTS OF WOOD DESTROYNIG FUNGI ON NATURAL DURABILITY OF EUCALYPTUS CAMALDULENSIS

Abstract

Comparisons of natural durability of Eucalyptus camaldulensis to four species of some fast-growing species such as Swietenia macrophylla, Peltophorum dasyrachis, Anthocephalus chinensis and Hevea brasiliensis infected by wood destroying fungi white rot and brown rot were investigated under room temperature condition. E. camaldulensis wood was evidently more susceptible to white rot and brown rot than the other wood species. White rot fungi Pycnuporus sanguineus which destroyed E. camaldulensis wood decay about 36.6%, as well as some fast-growing species, such as S. macrophylla, P. dasyrachis, A. chinensis and H. brasiliensis wood were deteriorated about 27.51%, 17.3%, 27.51% and 14.92%, respectively. The brown rot fungi Gloeophyllum sepiarium, moreover infected the amount of 47.06% E. camaldulensis 8.05% A. chinensis, 32.43% P. dasyrachis and 46.0% H. brasiliensis wood. However, E. camaldulensis could be resistant to some susceptible wood destroying fungi such as Coriolus sp. and Schizophyllum commune according to the species of wood destroying fungi and wood species.
