Descrição: The study aimed to evaluate the shrinkage, in the bottom-up and pith-bark direction, of the australian cedar wood from three Counties in the south of Minas Gerais state, and also to check the variation in chemical composition of wood due the location of planting. The australian cedar wood was obtained with four years of age and in three cities in the south of Minas Gerais state (Campo Belo, Cana Verde and Santo Antonio do Amparo). The chemical constituents of wood, shrinkage values (tangential, radial, longitudinal and volumetric) and the anisotropy coefficient. According to the results, there was no significant variation in the levels of holocellulose were determined, lignin, extractives and ashes between the three plantation sites evaluated. For the shrinkage of the wood in the bottom-up direction, there was no significant variation of the radial and longitudinal contractions for the three locations evaluated. However, significant variation was observed for the tangential and volumetric contractions for cities of Campo Belo and Cana Verde, and significant variation of Tangential contraction for the plantation of Santo Antonio do Amparo. In the pith-bark direction, significant variation was observed only on the radial contraction and the coefficient of anisotropy for location of Cana Verde.
