Inoculation of vesicular‐arbuscular mycorrhizal fungi on onion and tomato seeds

Abstract The growth of plants in sterile soil from seed pelleted with endotrophic mycorrhizal fungi was compared with non‐inoculated plants and with plants grown in sterile soil to which mycorrhizal spores were added. The dry weight of onion and tomato plants grown in the presence of mycorrhizal fungi was greater than the non‐mycorrhizal control treatments, in a range of soil‐vermiculite mixtures. There were no significant differences between the different methods of mycorrhizal inoculation.
