TL;DRAbstract

Wood of genus <i>Pinus </i>have been widely used by plywood Brazilian industry, motivated by their good physical and mechanical properties as well as reforestation policies. For plywood companies, quality control for its commercialization presents itself as essential. In this sense, this paper aims to evaluate, by means of physical properties, homogeneity of plywood manufacturing process using <i>Pinus</i> sp. So, we selected four panels, and extracted samples to obtain their physical properties. Analysis of variance (ANOVA) was used to investigate manufacture homogeneity of the panels. ANOVA results, for all physical properties investigated, had presented statistical equivalence, showing consistency of product manufacture, independent of the supplier company.
