Caracterização da cor da madeira de clones de híbridos de Eucalyptus ssp.

Abstract

Due to the importance of wood characterization and standardization, this research evaluated the variability of wood color inside and among Eucalyptus spp clones, as well as radially and longitudinally inside the trunk through the quantitative colorimetric color determination of clones of Eucalyptus wood., using CIELAB 1976 system, , through chromatic coordinates L*, a*, b*, C* e h. Eleven clones of natural Eucalyptus clones hybrids, cultivated at the Northwest of Minas Gerais State, were used. The results showed that: all colorimetric parameters were statistically different among clones, and among radial position of samples; it was possible to identify both clones and samples position along the ray, producing wood of different colours, but tending to yellowish and reddish tonalities.
