Description:
The influence of initial stand density and genetic population on corewood dynamic stiffness of 11-year-old Pinus radiata [D. Don] was investigated at a field trial in Canterbury, New Zealand. Corewood dynamic stiffness was determined on standing trees using the stress wave method over the lower stem (0.2-2.0m) of 182 trees, from an experiment which included three contrasting genetic populations (GF1, GF27 and clonal) grown at 833 and 2500stemsha^-^1. Stiffness was significantly influenced by planting density (P
