Abstract

The effect of moisture content (MC) on the drill resistance values during desorption from a watersaturated condition of Taiwania (Taiwania cryptomerioides Hayta) plantation lumber was examined. Results showed that the drill resistance values tended to decrease with the decreasing of MC. Positive significant relationships were found among the MC, bulk density, and drill resistance values. This adjustment of density profiles could help the RESISTOGRAPH® to achieve a better measurement of the drill resistance profile of standing trees.
