  1. The same characters indicate no significant difference by Tukey–Kramer test (p > 0.05)
  2. The samples for the 8-week test were taken from different logs with samples for 12-week test
  3. The mass-loss rates for 8-week decayed samples cannot be compared with those for 12-week decayed ones
  4. SD standard deviation of mass-loss rate
  5. * There was no significant difference between heartwood and sapwood (t-test p > 0.05)
