Résumé
This study aimed to compare the results of the analysis of the wood density profile of pine trees using the methodologies of X-ray densitometry for direct reading, usually applied in laboratories, and digital X-ray images, which dispenses the radiographic film. In the present study the radial wood samples of 5 Pinus elliottii var elliottii x Pinus caribaea var. hondurensis trees 7 years-10 months were used. The radial wood density profiles obtained by applying the two radiographic methods were similar. However, the methodology of digital X-rays provides additional benefits and qualitative results, greater agility in processing the wood analysis, and is therefore recommended in research that requires the evaluation of the density of a significant number of wood samples of coniferous and hardwoods trees.
