THE MYCORRHIZAL ASSOCIATIONS OF SOME AUSTRALIAN ASTERACEAE

Abstract

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.
