Abstract :
Wood properties were assessed on 23 eucalypt clones in southern China using non-destructive methods. They were sampled at 51 months. Correlations between three traits assessed using non-destructive methods and basic density measured on increment core showed that genotypic correlation between Pilodyn penetration and basic density was significantly negative (r = -0.83), indicating that basic density could be predicted using Pilodyn. The correlation between basic density and modulus of elasticity was significantly positive (r = 0.74). Stress wave velocity was unfavourably correlated with Pilodyn penetration (r = -0.20) but correlated with basic density (r = 0.52) and modulus of elasticity (r = 0.96). This indicates that basic density and modulus of elasticity can be predicted using stress wave velocity.
