| Popis: | In Rio Grande do Sul state, the eucalyptus planted forests are cultivated in low fertility soils, which contribute to ectomycorrhizal association. This study evaluated the effect of ectomycorrhizal isolates UFSC-Pt116, UFSC-Pt188 and UFSC-SA9 inoculation, individually and in combination, with Eucalyptus grandis in Quartzarenic Neosols. Evaluations were performed at 30, 45, 60, 75 and 90 days after sowing. Plants inoculated with isolates UFSC-Pt116, UFSC-Pt188 and UFSC-SA9 showed highest height, stem diameter, dry mass of shoot and root volume than the control. Plants inoculated with the ectomycorrhizal fungus isolate UFSC-Pt188 showed highest content of phosphorus and potassium in shoots than non-inoculated plants. Inoculation individual ectomycorrhizal isolate UFSC-Pt116 promoted the highest height and shoot dry mass. For nitrogen and potassium, and root biomass have not showed significant differences between treatments. Then inoculation with ectomycorrhizal UFSC-Pt116, UFSC-Pt188 and UFSC-SA9 alone promoted highest height, stem diameter, dry mass of shoot and plant root volume of Eucalyptus grandis. |
