The research analyzed the quality of the preservative treatment of Eucalyptus camaldulensis Dehnh juvenile wood and verified the influence of the inversion of the pieces, in preservative solution, in the distribution, penetration and retention of CCB in treated pieces. Trees of Eucalyptus camaldulensis were collected in the rural area of the municipality of Rio Tinto, Paraíba, Brazil, in a stand aged four years. In the stand were randomly chosen five trees, being three of them with the larger diameter. For the wood treatment it was used the sap displacement method by radial transpiration using a 2% solution of ingredients copper chrome borate (CCB) and compared the effect of the inversion of pieces on the preservative solution. The distribution, penetration and retention were better in reversed pieces when compared with the ones non-reversed in the preservative solution.
