Abstract

Bioassay measurement was used to estimate the inoculum potential of mycorrhizal fungi in intact soils collected from Eucalypt us plantations of varying ages in Western Australia. The results showed that both ectomycorrhizal ( ECM) and vesicular2arbuscular mycorrhizal (VAM) fungi existed in soils from most plantation sites according to two bait plants(clover for VAM and Eucalypt us for ECM) . The levels of ECM or VAM fungal inoculum were considered to be moderate. Analysis of roots sampled from plantations suggest that Eucalypt us stands are more associated with VAM fungi compared to ECM fungi that occupied most fine roots in older stands. Information from the bioassay experiment suggests that there may be a need for the introduction of a wider range of inoculum to assist the establishment of new Eucalypt us plantations in this region. Further work is required on below2ground ECM fungal diversity in these plantations.
