抄録	We studied the colonization of ectomycorrhizal fungi and species abundance of a hybrid larch (F-1) under elevated CO2 and O-3. Two-year-old seedlings were planted in an Open-Top-Chamber system with treatments: Control (O-3 < 6 nmol/mol), O-3 (60 nmol/mol), CO2 (600 mu mol/mol), and CO2 + O-3. After two growing seasons, ectomycorrhiza (ECM) colonization and root biomass increased under elevated CO2. Additionally, O-3 impaired ECM colonization and species richness, and reduced stem biomass. However, there was no clear inhibition of photosynthetic capacity by O-3. Concentrations of Al, Fe, Mo, and P in needles were reduced by O-3, while K and Mg in the roots increased. This might explain the distinct change in ECM colonization rate and diversity. No effects of combined fumigation were observed in any parameters except the P concentration in needles. The tolerance of F-1 to O-3 might potentially be related to a shift in ECM community structure. (C) 2014 Elsevier Ltd. All rights reserved.
