In the Rio Grande do Sul state, where eucalyptus reforestation is common in low fertility soils, the seedling
performance may depend on the ectomycorrhizal association. In this paper, the inoculation effects of
UFSC-Pt116, UFSC-Pt188 and UFSC-SA9 ectomycorrhizal fungi isolates, individually and in mixture, on
Eucalyptus grandis
seedlings were evaluated. Evaluations were performed at 30, 45, 60, 75, and 90 days
after sowing. The individual inoculation of UFSC-Pt116 isolate promoted highest height and aerial dry
mass. The seedlings inoculated with the mixture UFSC-Pt116 + UFSC-Pt188 + UFSC-SA9 accumulated
highest amounts of phosphorus at 90 days. The nitrogen and potassium concentrations, and root dry mass
did not show significant differences among the treatments.
