Improving log and wood quality: The role of the radiata pine improvement programme

M.J. Carson

Tree improvement of radiata pine has emphasized improvement in tree health, growth rate, stem form, and log and wood quality. Increased growth rate and better stem form will significantly increase profitability through reductions in growing costs and increases in piece size, but timber in knotty pine grades will increase at the expense of a reduction in clear-cuttings grades. Recognition of the risks and uncertainty associated with the prediction of market niche and price premiums for 30 years in the future supports the use of a simple, flexible tree improvement strategy.
