Abstract

The effect of environment on growth-stress splitting, wood density, fibre length, shrinkage and heartwood content was studied using 31 five-year-old eucalypt clones, mostly Eucalyptus grandis and E. grandis-based hybrids, grown in replicated trials at 26 sites. An analysis of variance was carried out for each wood property to test the interaction between site and clone. For each clone a linear regression of the individual property value on the mean of all clones for each site was computed as a further measure of clone-by-site interaction.
