In the second part, an in situ experiment of rhizobial inoculation was performed on eightselected tree species belonging to three genera: Albizia Erythrophleum Millettia. · Of the 97 plant species and 14 generathat had never een examined before this study, 31 species and our genera were reported to be nodulted. After 4 months of growing ina nursery and a futher 11 months after transplantationof plants to the field, we observed a highly significant (P &lt 0.001) and positive effect of inoculation with Bradyrhizobium sp. strains on the growth of the eight, tree species tested.  · The importance of determining the nodulation ability of nexplored local trees and subsequently using this information for inoculation in reforestation programmes was demostrated.  anodulation  atrees  aÁrvore  aInoculação  aNodulação  aInoculation1 aMUNIVE, A.1 aFARIA, S.
