| The aim of this study was to compare three alternative methods to determine the moisture content of wood logs with the method recommended by ABNT. The moisture content of the wood was determined in a sawdust sample and with a electric meter capacitive. it was also determined the moisture content of a disk sample using the method recommended by ABNT. Using the regression model, all the methods were statistically similar. It was concluded that the use of alternative methods for determining the moisture content of wood in logs is feasible, to substitute the traditional method, but corrections must be implemented. |

| Due to the lack of information about wood properties and charcoal quality from native species, this work was carried out aiming at to characterize the wood anatomical structure of Piptadenia gonoacantha and determine the yield and properties of charcoal. The wood anatomy was described, and it was determined the fibers and vessels dimensions, basic density and higher heating value (HHV). Bulk density, chemical analysis, and HHV were determined for charcoal. The average vessel diameter was 121.30 μm, with 15 vessels mm-2. The fiber dimensions were: length, 0.82 mm, width, 17.54 μm, lumen diameter, 8.02 μm, wall thickness, 4.76 μm, and wall fraction of 54.28%. The basic wood density was 590 kg m-³ and HHV was 4650 kcal kg-1. The charcoal yield was 37.10%. The... |
