Abstract

The establishment of exotic forest species in Brazil may show  dependence to ectomycorrhizal association, which increases the resistance of seedlings to stress after the initial planting in the  field, favoring the maintenance of harshseedlings under  adverse conditions. The study aimed to evaluate the effect of  applying the eucalyptus essential oil in ectomycorrhizal  colonization on growth of Eucalyptus grandis seedlings in greenhouse conditions. The treatments consisted of five  concentrations of the Eucayptus grandis essential oil and two  ectomycorrhizal isolates, in addition to the control treatment  without inoculation. It was used a completely randomized  design with eight repetitions. Ninety days after transplanting  the eucalyptus seedlings were evaluated: height (cm), stem  diameter (mm), dry massof shoots and roots (mg) and percentage of ectomycorrhizal colonization. The eucalyptus  essential oil was efficient in stimulating ectomycorrhizal  colonization of eucalyptus seedlings, resulting in significant  increases in dry weight of shoots of mycorrhizal seedlings,  showing doseresponse effect, depending on the ectomycorrhizal used.
