| Sumario: | To evaluate growth stresses in Eucalyptus dunnii and determine the effect of physical wood properties on that variable, a total of 45 trees were sampled from a 19-years-old trial located at Corrientes, Argentina. Growth stresses were determined using the growth stress indicator (GSI, CIRAD-Forêt) and the log end split index (IR). The physical wood properties basic density and total volumetric shrinkage were measured and the pith-to-bark gradient of the basic density was determined. GSI and IR values obtained were lower than those cited for the species (GSI: 0,0763 0,0251mm and IR: 0,43 0,31%) and showed good association between themselves (r: 0,71). A low association between growth stresses and the physical wood properties basic density (r: 0,35-0,39) and volumetric shrinkage total (r: 0,29-0,35) was founded. The association levels were higher when growth stresses (GSI and IR) and the pith-to-bark gradient of the basic density (r: 0,59-0,52) were correlated. |
