Nowadays the management of some species have been uncertain, since wood quality and yield are becoming lower than expected. Heartwood content is a determinant characteristic for <em>Bombacopsis quinata</em>, a widely appreciated species in the country. The aim of this study was to evaluate the heartwood, sapwood and bark content of young and advanced aged <em>B. quinata</em> trees. The research was based on the hypothesis that heartwood content increases with increasing age. By means of stem analysis, the heartwood, sapwood, and bark volume was measured on<br>trees of different ages (10 to 27 years). The highest heartwood proportion found in <em>B. quinata</em> was 13.6%, and the lowest 0.1%. The sapwood ranged between 70.0 and 87.2% while the bark, from 9.4 to 23% of the total stem volume. No clear differences in heartwood content could be observed between trees of similar age from dry and wet zones. Rotation periods for <em>B. quinata</em> in Costa Rica should be extended to produce high quality timber with increased heartwood content.</p> ER -
