The effect of different sewage sludge levels (0%, 1%, 4%) on mycorrhizal infections, spore dens-i ties, root and shoot biomass, Cu uptake by maize inoculated with three arbuscular mycorrhizal fungi (A.laevis, G.caledonium and G.manihotis) in the red soil was studied.Mycorrhizal infection, spore densities, root and shoot biomass were increased by 1% sewage sludge in comparison to no sewage sludge when the maize was inoculated with A.laevis, however, mycorrhizal infection, spore densities, and root and shoot biomass were greatly reduced in the three other treatments (p < 0.05).When the red soil was amended with 1% sewage sludge the Cu concentrations in the shoot of the maize were NM (noninoculation) > G.manihotis> G.caledonium> A.laevis, and the total Cu content in the root of the maize infected with the three mycorrhizal fungi was higher than that under nonmycorrhizal treatment.The results showed that the tolerance of different arbuscular mycorrhizal fungi to heavy metals varied and A.laevis could remediate heavy metal contaminated soil when the heavy metal concentrations were not very high.
