Abstract

The variations of Vtree, Vlumber, MOEtree, and MOElumber in the thinning and pruning treatments showed the similar trend. Results of this study also demonstrate that the effect of silvicultural practices on wood properties can be identified with the ultrasonic-wave properties of trees. This indicates that this non-destructive ultrasonic-wave technique can be provided basic information for future management practice and wood utilization of Taiwania.
