Wood presents great variation in longitudinal, transversal, radial and tangential direction. The variation in the radial direction is the most perceptible and important for wood uses. This research aimed at evaluating the influence of the wood radial sampling position in the charcoal quality of six Eucalyptus clones. For evaluating the experiment it was adopted the randomized design disposed in split plot, where clone represented the effect of the plot and radial position the effect of the split. The results indicated that the clone effect was significant for charcoal and fixed carbon yield, apparent relative density and fixed carbon content. The effect of radial position was significant for apparent relative density, volatile materials and fixed carbon content. The effect of clone x radial interaction position was significant for charcoal yield, volatile materials and fixed carbon content. The significance of the interaction indicates that the clone effect depends on the levels of the effect of the radial position, evidencing dependence between the two factors.
