Determinação da densidade básica das madeiras de Amburana cearensis (Allem.) A. C. Smith E Piptadenia stipulacea (Benth.) Ducke.

Abstract

This study aimed to determine the average density (DBM) of wood Amburana cearensis (allem.) a. c. sm. and Piptadenia stipulacea (Benth.) Ducke. Five trees were randomly collected by species that had good health, St. Benedict the site located in the city of Patos-PB. Discs were removed from each tree for determining the average density (DBM) and the remainder reserved for chemical analysis and subsequent studies of the quality of the wood species. The average density was determined by the method of immersion in water. It was found that the average values of the average density between the two species showed significant differences, the Piptadenia stipulacea showed the highest value and A. cearensis DBM showed lower value and the average values found 1.00 and 0.63 g / cm ³ respectively. The results indicate a good adequacy of the two species for various technological purposes.
