N2  - Despite of the great diversity of Brazilian forests, only a few species are well known and commercialized, but many others could provide wood with potential applications in the wood industry. In this study, heat treatment was analyzed as a way to add value to low market valued tropical woods. The effect of heat treatment performed at 160 and 220°C was assessed on color, weight loss, specific gravity, and equilibrium moisture content (EMC)of cedroarana {Cedrelinga catenaeformis)and cedro-marinheiro (Guarea trichilioides)woods. Heat treatments caused weight loss, darkening, and decreased EMC, as the maximum temperature increased. However, no changes in specific gravity were observed as a function of heating. Cedro-marinheiro has presented the highest changes in color and weight as a function of heating, while cedroarana has shown the highest reduction in EMC. Heat treatments improved some wood properties, being a good approach to improve low market valued tropical woods. Results also suggest that resilience to reduction of hygroscopicity after heating might be related to wood specific gravity
