THE MYCORRHIZAL ASSOCIATIONS OF SOME AUSTRALIAN ASTERACEAE

Authors


SUMMARY

Some 80 species of Australian Asteraceae were examined for their ability to form ectomycorrhizal associations. Twenty-seven species, all but one belonging to the tribe Inuleae, were found to form both ectomycorrhizas and vesicular-arbuscular mycorrhizas. Species found to form ectomycorrhizas belong to Angianthus (sensu stricto), Podolepis, Pogonotepis, Waitzea, Helichrysum (pro parte) and Helipterum (pro parte); all are annual or perennial herbs. Four species shown to form ectomycorrhizas gave significant growth responses to inoculation with either an ecto-or endomycorrhizal fungus in soil low in available phosphate.
