Abstract
This study aimed to evaluate the physical and mechanical properties of the wood of Chrysophyllum marginatum (Hook. And Arn.) Radlk. We used three trees with 20.3 ± 6 cm of diameter. It was determined by regression analysis the variation bottom-up of shrinkage, anisotropic coefficient, saturate moisture content and basic density. To characterize the static bending in the first log, in saturate and air dried conditions, it was performed variance analysis using Tukey›s test. It was observed a decrease in radial and tangential contractions and basic density on bottom-up direction. Saturate moisture content increased, considering the same direction. Anisotropic coefficient presented increase tendency up to 1.30 m height followed by stabilization from that position to the top. It was observed decreasing tendency of longitudinal contraction to approximately 40% of total height, followed by increasing up to the insertion of the first living branch. Mean anisotropic coefficient and basic density were 2.3kg m-³ and 594 kg m-³, respectively. Air dry condition showed greater static bending resistance than when saturate. Values of rupture and elasticity modulus were similar to those found in studies with Eucalyptus saligna and Carya illinoinensis.
