Influence of inoculation with arbuscular mycorrhizal fungi on the growth and mycorrhizal infection of transplanted onion

摘要: Abstract Effects of inoculation with arbuscular mycorrhizal (AM) fungi on the growth and infection onion were observed in five field experiments. Onion seedlings pre-inoculated multiple trays peat substratum transplanted after 6 weeks to plots containing steamed, fumigated or non-sterilised soil. Positive responses found most fungal endophytes tested. Inoculated AM generally more effective than indigenous from The plant response was higher when soil eliminated by steam sterilisation fumigation. In one experiment, non-fertilised non-irrigated treatments, but plants inoculated some significant even fertilised irrigated.
