摘要

•Sites with tephra had N. pumilio regeneration and low understory plant richness.•Nothofagus pumilio seedlings in the tephra had ectomycorrhizal fungi (EM).•Differences in plant growth and EM behavior were observed between sites.•The composition of EM communities in the tephra was different from that in forest soil.•EM are an effective adaptation mechanism for stressful, post-eruption conditions.
