Abstract

The aim of present study was to define the age of segregation of the woods of Luehea divaricata, Platanus x acerifolia and Carya illinoinensis, by Modulus of Rupture (MOR) and Modulus of Elasticity (MOE). To this end, test specimens were prepared in the radial direction and static bending tests were carried out in universal testing machine. To determine the zone of transition between juvenile and mature wood, the data were plotted in the radial direction individually for each tree, a regression was used to estimate the variation of data in general, and another linear regression was used at the initial linear points. The boundary of the increasing part of the data determined the transition zone between juvenile and mature wood. The results showed that there was no difference in age of transition, for each species, in relation to the property (MOR and MOE) used to delimit the transition zone. The following average ages of transition were obtained: 9.3 years for Platanus x acerifolia, 11.8 years for Carya illinoinensis and 23.8 years for Luehea divaricata.
