dc.description.abstract | Energy forests emerge as an alternative to fossil fuels for energy production. The good performance of these forests should consider the selection of fast-growing species, high biomass productivity and energy yield. The aim was to investigate growth and energy yield of Acacia auriculiformis and Acacia mangium in a short-rotation plantation in the Amazonas. The energy yield was determined on 12 trees per species, from the results of biomass, calorific value and basic density. When 9 years-old, A. mangium had the highest growth rates in height (1.9 m yr-1) and DBH (2.5 cm yr-1). The greatest biomass productivity was observed in A. mangium (33.4 Mg ha-1 yr-1), which was 84% higher than A. auriculiformis (18.1 Mg ha-1 yr-1). Basic density (0.54 g cm-3) and calorific value (4,400 kcal kg-1) showed no significant differences between species. The energy yield of A. mangium (1,317 Gcal ha-1) was twice as of A. auriculiformis (684 Gcal ha-1). A. mangium has better energy performance, compared to the A. auriculiformis, and therefore could the most recommended for the formation of energy forests in disturbed areas in the state of Amazonas. | en |
