Summary
Nitrogenase activity, measured by acetylene reduction, was detected on nursery-grown, surface-sterilized ectomycorrhizae of Douglas-fir, formed withLaccaria laccata, Hebeloma crustuliniforme, Rhizopogon vinicolor, andThelephora sp. Detached mycorrhizae were incubated in nitrogen-free liquid medium under microaerophilic conditions. Nitrogenase activity was attributed toClostridium spp. andAzospirillum spp.
