Abstract

One of the fast growing species cultivated in Uruguay of major economical importance is Eucalyptus grandis. Physical and mechanical properties of juvenile and mature wood from different regions have been reported. However, since no scientific data of natural durability of this specie has been reported, natural durability of E. grandis from two sites (Rivera and Río Negro) was evaluated. Two sixteen years old plantations, originated by seed of same source, were sampled. Natural durability of outer and inner heartwood was studied following EN 350-1 methods. Populus deltoides x euroamericana cv I-214 was tested as reference specie. EN 113 laboratory tests for fungal decay (Gloeophyllum trabeum, Trametes versicolor and Serpula lacrymans) and EN 118 for termites resistance (Reticulitermes spp.) were performed. Field stakes, double layer and fungal cellar tests were established. They are still on course and partial results are reported below in this paper. Upon basic density radial profiles, it was found that outer heartwood was not mature wood, but can be assumed as transition wood. In general, E. grandis heartwood showed higher durability than Populus hybrid. E. grandis appeared moderately or seriously attacked by Reticulitermes spp. E. grandis juvenile wood can be classified according EN 350-1, as “Moderately Durable” against the brown rotter G. trabeum, whereas transition wood can be described as “Durable”.
