We also inoculated cottonwood clone 895 with 6 ectomycorrhizal fungi. It was found that Xerocomus chrysenteron, Lactarius insulsus and Boletus edulis accelerated seedlings generation from cuttings of clone 895 more than the other fungi did, and they remarkably promoted seedling growth comparing with the control. Lactarius insulsus promoted above-ground biomass and root system most effectively.
