Abstract: This work aimed the evaluation of 15 (fifteen) provenances of three eucalypt species: Eucalyptus cloeziana, Eucalyptus grandis and Eucalyptus saligna. The trees were 31 years old and the test was developed in the campus of the Universidade Federal de Lavras. Six particleboards for each provenance were made by using the residues generated in the veneer production of this material. It was used urea-formaldehyde at 8% resin level and paraffin at 1%, both according to their respective solid content. The boards were produced by using a pressing cycle with temperature of 160 ºC, specific pressure of 40kgf/cm² and pressing time of 8 minutes. From the results, it was concluded that the specie Eucalyptus saligna was the best one in terms of water absorption. The 43 provenance of Eucalyptus grandis showed the best development of thickness swelling. Superior results of compression and elastic modulus were found to Eucalyptus cloeziana. The provenance of number 10695 of the specie Eucalyptus grandis presented the bestresults for elastic and rupture modulus. In general, the provenance 10695 and species of Eucalyptus grandis showed the greatest potential for production of particleboard.
