Abstract
In experimental microcosms, 3 Glomus spp. (2 Glomus
spp. and 1 G. macrocarpum) were subjected to heating to over
200 deg C at the soil surface and 70 deg at 5 cm to determine the effect
of fire on survival of arbuscular mycorrhizal fungi. Heating reduced the
quantity of propagules surviving at the soil surface and the effect declined
with depth. While all propagules are likely to be affected by heat, it
is argued that the hyphal network is most severely disturbed and probably
responsible for declines in density of fungi observed in the field following
fire.
