Evaluation of Full-Sib Families of Douglas-fir in a Nelder Design
Thirty Douglas-fir full-sib families and an unselected check were evaluated in a Nelder's design covering a range of densities from 735 to 26,300 trees/ha. Regression analysis resulted in good overall fits of volume and caliper to density with the power function (y = ax b ), and indicated differential response of families to density.
