CHANGES IN WOOD MICROSTRUCTURE THROUGH PROGRESSIVE STAGES OF DECAY.
Abstract
The sequence of changes observed microscopically that occurred in wood throughout successive stages of decay was studied in the sapwood of a hardwood, sweetgum (Liquidambar styraciflua L.), and of a softwood, southern pine (Pinus sp.). The fungi used were Polyporus versicolor L. ex Fr., a white-rot fungus, and Poria monticola Murr., a brown-rot fungus. Light microscopy, plus the techniques of polarization and ultraviolet-absorption microscopy, was used to make the observations on sections 4 microns thick cut from celloidin-embedded specimens.
