INFLUENCE OF HARVEST REGION ON PROPERTIES OF CAMBARA WOOD

This research intends to evaluate the relation, aided by the Brazilian Standard and statistical analysis (Kruskal-Wallis ANOVA and bootstrap technique), between physical and mechanical properties of Cambara-Rosa wood harvested from three different regions: Vera, Mucajai and South Rondonia. In addition, the possibility to estimate (regression models) physical and mechanical properties in function of apparent density was analyzed. Different climate and soil conditions which tree thrives may influence its growth and, consequently, its properties values. The results of ANOVA indicated an elevated equivalence index for all three regions. The bootstrap technique led to similar results for Vera and Mucajai regions, and for South Rondonia region, equivalence index equals to 89 %. The ANOVA results to estimate physical and mechanical properties in function of apparent density indicated that it is not possible to perform such estimates for Cambara-Rosa wood species.

Automated summary

This research evaluates the relationship between physical and mechanical properties of Cambara-Rosa wood from different regions, indicating that climate and soil conditions may influence the properties values. Results show high equivalence index for all regions, with regression models unable to estimate the properties based on apparent density.
