Proportion of juvenile wood of açoita-cavalo, pecan and London plane wood

Abstract This study aims to define the proportion of juvenile wood of açoita-cavalo (Luehea divaricata), pecan (Carya illinoinensis) and London plane (Platanus x acerifolia) wood. Five trees of each species were selected in two regions of a state in the south of Brazil. Discs 2 cm thick were cut at 10 cm from the base, the proportion of juvenile wood was measured based on the radial distance of each annual ring and the segregation age of the juvenile wood was determined from the diameter of the base of the trunks. The results showed that Luehea divaricata wood had the lowest proportion of juvenile wood in both regions. Furthermore, the proportion of juvenile wood presented high correlation with both the age and the diameter of the trees.
