چکیده
|
Collapse occurs in certain species such as in some members of the genus eucalyptus. this study aimed to assess the degree of collapse developed during drying of e. saligna at different temperatures and determine its collapse threshold temperature range. the presence of internal checks and the number of samples with a washboarding effect on the surface of the board were used as indicators for collapse. results showed boards dried at 30 °c had the highest percentage of cross-section loss due to internal checks. on the other hand,the highest number of samples with corrugated surface was found for boards dried at 35 °c. eucalytus saligna had a collapse threshold temperature range below 20 °c. © forest research institute malaysia.
