The results show that Dipteryx odorata recorded the least shrinkage rate and the biggest density, resistance to bending, MOE, compression strength parallel to grain, compression strength perpendicular to grain and impact ductility in the three species. Its quality belongs to the highest grade. The tangential direction shrinkage rate and impact ductility of Pometia spp. are less than those of Quercus spp. The other physical and mechanical properties of Pometia spp. are bigger than those of Quercus spp. Its quality belongs to high grade, except for its tangential direction shrink- age and impact ductility which are bi
