In Western Australia, Trametes versicolor, Pycnoporus coccineus, Stereum hirsutum, Stereum illudens and two unidentified basidiomycetes (species A and species B), are all commonly observed fruiting and causing decay on Eucalyptus globulus coppice stumps. In some instances, fungal rot on colonised stump has been observed moving into the emerging coppice shoots. Depending on the severity of decay this could threaten the productivity of the coppice rotation by affecting wood quality or causing complete loss of trees due to wind-throw. A trial was set up in an 18-24 month old E. globulus coppice plantation to test the relative ability of each of the commonly observed fungi to decay wood of actively growing coppice shoots. Each of the six species was inoculated into coppice shoots using wooden dowels previously colonised in the laboratory. Three inoculations were made at 5 cm, 30 cm and 1 m from the top of the stump surface along the coppice shoot. A hole slightly larger than the dowel was drilled at each inoculation point, the dowel introduced and then covered with Parafilm™. Control inoculations were performed by inoculating a separate coppice stem on the same stump with sterile dowels. All coppice shoots were harvested after 6 months. Decay was assessed by measuring and calculating the volume of lesions or discoloration at the point of inoculation. Differences in wood density between sound and discoloured wood were also measured. Results arising from this investigation will be presented and discussed.
