Resumo: | Minquartia guianensis Aubl. (acariquara) occurs at Acre, Amazonas, Roraima, Pará and Amapá states, with a great market demand and utility in the Amazon region. It is used mainly in civil construction due to its high durability and singular beauty, because of reentrances in its trunk, resulting in high market value. Most of used trees present small diameters, what is a critical factor for their management and commercialization. Thus, the objective of this study was to evaluate M. guianensis diametric growth and cutting cycle through the analysis of time of passage among diameter classes, 31 years after logging, at Tapajós National Forest, Pará State, Brazil. Five treatments were established and in each one 12 permanent sample plots of 0.25 ha were installed. All trees with diameter at 1.3 m above ground level (DBH) ≥ 5 cm were measured from 1981 to 2012. Trees with DBH ≤ 50 cm have potential to be managed, due to the growth stagnation presented in larger diameter classes. These results may support silvicultural decisions to sustainable management.
