Descrição: The aim of this study was to analyse the influence of thinning and fertilization on some log properties which influence sawn wood yield in a 21 year-old grown Eucalyptus grandis stand. Three selective thinning intensities (37, 50 and 75%), presence or absence of fertilizers on the beginning of the thinning, two diameter classes and two logs taken from two different vertical positions were taken as the study factors. The influence of the factors and their combination on tree growth stresses were indirectly evaluate through log end splitting and pith displacement in relation to its normal central position. Thinning, fertilization, diameter class and log position on the tree height did not have significant effect on pith displacement. The logs from fertilized plots presented higher log end splitting index than others.
