要旨本文	To assess an interaction between ectomycorrhizal (ECM) and arbuscular mycorrhizal (AM) fungi in the same host, a split root assay was conducted in the seedlings of P. tomentosa with equally separating lateral roots into two root systems. One root system of each seedling was inoculated with ECM fungi, either Cenococcum geophilum (Cg) or Laccaria japonica (Lj), and then co-inoculated with AM fungus Rhizophagus irregularis (Ri) in either the same or the other root system. After 12 weeks, AM and ECM colonization rates were measured. The Cg ECM roots showed a significant decrease in all treatments with Ri co-colonization, whereas Lj was notably affected only when co-inoculated with Ri in the same root system. This result indicates that AM could both locally and systematically affect ECM negatively.
