| metadata.revistascielo.dc.description: | This study evaluated the phenotypic, genetic and environmental parameters for the following wood physical properties: basic density, radial, tangential, volumetric shrinkage and anisotropy coefficient. It also assessed the indirect genetic gains in the physical properties of wood by the selection of amplitude for longitudinal residual strains evaluated using a non-destructive method. A total of 13 Eucalyptus clones aged 10 years were used. The experiment was established in a completely randomized design with three replicates. The non-destructive measures were evaluated using extensometer and resistograph. After the quantification of those characteristics, the sawing of the logs was performed and 70.0 cm samples were removed from the top of each board for the making of specimens preparation and determination of physical properties of wood. The heritability values for the basic density, radial, tangential, volumetric shrinkage and the anisotropy coefficient were considered high 96, 90, 94, 92 and 72, respectively. It was found that indirect genetic gains in the basic density can be efficiently reached when selecting for amplitude, supplied by the resistograph. The resistograph proved efficient to evaluate genetic materials in the field. |
