- Genotypic variation in wood total and partial shrinkage, basic density and growth traits was estimated in 51/2 year old Acacia auriculiformis trees in a clonal test.In the tangential, radial and longitudinal directions, the mean values were 2.64%, 1.64% and 0.77% for partial shrinkage, and 5.92%, 3.23%, and 0.96% for total shrinkage, respectively. Total and partial transverse shrinkage were significantly greater in sapwood than in heartwood.Clonal repeatability (H(C)(2)) estimates for partial shrinkage were lower than those for total shrinkage, and heartwood shrinkages had lower H(C)(2) than those for sapwood. Estimates of H(C)(2) were from 0.32 to 0.38 for total transverse shrinkage, comparable to H(C)(2) for both total and partial volumetric shrinkages (0.40 and 0.32, respectively). However, H(C)(2) for longitudinal shrinkages, total and partial coefficients of anisotropy were only from 0.09 to 0.18.The genotypic coefficients of variation of all shrinkage traits varied from 5.45% to 8.02%. Total shrinkage was strongly positively correlated with partial shrinkage in each dimension. Genotypic correlations were not significant between shrinkage and growth traits or density. Strong and significant correlations between transverse shrinkage in heartwood and sapwood (0.87) indicated that juvenile shrinkage is a good genetic indicator of this trait in older trees.Utilisation du retrait du bois dans l'amelioration de l'Acacia auriculiformis A.
