| Description: | Vochysia guatemalensis Donn Sm. wood is currently provided from plantations in several regions of Costa Rica. This wood presents several problems during the drying process such as high variability in the moisture content and high incidence of later defects. The objective of this study was to investigate the causes of this variation and defect developments. It was considered climate condition or precedence, grain pattern, drying schedule, boards position in relation to height and distance from to pith and heartwood presence. The main factors affecting the moisture variability and drying defects were found to be: high initial moisture content variability in different parts of the tree, climate condition, and improper drying programs. Besides, there are recommendations to consider before starting the drying process. Thus a better wood quality in relation to moisture content variability and the presence of defects can be obtained after drying process. |
