Resumo: | The objective of this study was to evaluate the accuracy of nondestructive variables in inferring basic density of wood from Eucalyptus grandis and Eucalyptus urophylla. A total of 27 clones of Eucalyptus urophylla and 22 clones of Eucalyptus grandis were used, sourced from a clonal trial set up in Martinho Campos, Minas Gerais. After evaluation using nondestructive techniques of resistography and pin penetration at a constant pressure (Pilodyn®), individuals were felled and disks were removed from the 2%, 10%, 30%, 50% and 70% portions of the merchantable height section, and also from the portion 1.30 m above ground level. Basic density was determined by the water immersion method. Values of basic density ranged from 0.412 to 0.609 g.cm-3 for clones at age 42 months and from 0.408 to 0.664 g.cm-3 for clones at age 54 months. The clones of Eucalyptus urophylla provided higher values of average basic density in relation to Eucalyptus grandis. The variable ‘amplitude’ had better correlation with basic density in comparison with pin penetration at a constant pressure. Nondestructive evaluation can be used in mass preselection of genetic materials, prior to subjecting them to a more accurate, reliable evaluation. |

Foram utilizados 27 clones de Eucalyptus urophylla e 22 clones de Eucalyptus grandis oriundos de teste clonal implantado em Martinho Campos, Minas Gerais. Após a avaliação por técnicas não destrutivas de resistografia e penetração por um pino à pressão constante (Pilodyn® ), os indivíduos foram abatidos e retirados discos a 2, 10, 30, 50 e 70% da altura comercial, além destes, foram extraídos também discos a 1,30 metros do solo. A densidade básica da madeira foi determinada pelo método de imersão em água. Os clones avaliados apresentaram valores em densidade básica variando de 0,412 a 0,609 g.cm-3 aos 42 meses e 0,408 a 0,664 g.cm-3 aos 54 meses. Os clones de Eucalyptus urophylla apresentaram densidade básica média superior em relação aos de Eucalyptus grandis. A variável amplitude apresentou melhor relação com a densidade básica comparada a penetração por um pino à pressão constante. A avaliação não destrutiva pode ser utilizada em uma pré-seleção massal de materiais genéticos, destinando-os posteriormente a uma avaliação mais precisa e confiável.Universidade Federal de Lavras (UFLA)2016-04-052017-08-01T20:14:35Z2017-08-01T20:14:35Z2017-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfCOUTO, A.
