Table 6 Correlation coefficients between growth characteristics, SWV, and Py of 15 clones of teak trees at the two test sites

From: Growth characteristics, stress-wave velocity, and Pilodyn penetration of 15 clones of 12-year-old Tectona grandis trees planted at two different sites in Indonesia

  1. Values in lower side of diagonal and upper side of diagonal showed correlation coefficients in Cepu and Ciamis, respectively. Used data, mean values from 15 clones
  2. D stem diameter, H tree height, V bole volume, SWV stress-wave velocity, Py Pilodyn penetration, ns no significance
  3. ** Significance at the 1 % level
