Wood (Cebo/Mayo) Consideraciones durante el secado convencional de la madera de Vochysia Guatemalensis Donn Sm. (Cebo/Mayo) Moya Roque, Róger Tenorio Monge, Carolina Aguilar Tovar, Diana fast-growth plantations tropical species wood quality wet pockets drying defects plantaciones de rápido crecimiento especies tropicales calidad de madera bolsas de humedad defectos 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. La madera de Vochysia guatemalensis Donn Sm. actualmente se obtiene de plantaciones forestales en diversas regiones de Costa Rica. La alta variabilidad en el contenido de humedad final (CHf) y la alta incidencia de defectos presentes en el proceso de secado constituyen la principal problemática de esta madera. Se investigaron las causas de estos problemas, al tomar en cuenta factores como el clima o procedencia de la madera, el patrón de corte aplicado en el aserrío, el tipo de programa de secado utilizado, la posición radial de la tabla en la troza (distancia de la médula) y la presencia de albura o duramen. Se concluyó que las causas principales de esta variación y del desarrollo de estos defectos son: la alta variabilidad en el contenido de humedad inicial de la madera, la procedencia y los programas de secado inapropiados. Así mismo, se proponen una serie de recomendaciones a considerar antes de iniciar el secado para de esta manera lograr una mejor calidad de madera en cuanto al CHf y la presencia de defectos.
