  1. n number of trees, D stem diameter at 1.3 m above the ground, TH tree height, SWV stress-wave velocity, SD standard deviation, H2 broad-sense heritability
  2. Vf, Vb, Vfb, and Vr represent variance components ratio of family, block, interaction between family and block, and residual, respectively
