Colonisation of Wood by Soft-Rot Fungi

Conference paper

Summary

Colonisation of Pinus radiata D. Don sapwood by soft-rot fungi was examined by sequential light microscopy. The wood was exposed under various conditions of both natural infection and infection by pure culture. Soft-rot was more pronounced in wood exposed in undisturbed, unsterile soils than in unsterile, sieved soil or sterilised soil inoculated with pure cultures of Chaetomium globosum Kunze. When pure cultures of Chaetomium globosum were grown in a synthetic soil (acid-washed sand plus nutrients), soft-rot development in the exposed timber was as good as, if not better than, that in undisturbed, unsterile soil.
