Biodegradation of Hevea brasiliensis wood by Rigidoporus lignosus and Phellinus noxius1

In vitro wood slats degradation assays reveal that both the white root rot fungus R. lignosus and the brown root rot fungus P. noxius cause a white rot of wood. In vivo (infected tap roots) they cause the same type of decay. Nevertheless lignin determination show the rubber‐tree ability to react against the parasite aggression by increased lignification of tissues.
