Estimation of Basic Density and Modulus of Elasticity of Eucalypt Clones in Southern China Using Non-destructive Methods

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.
