摘要：

The variation of the retratibility in lumber is the main cause of the occurrence of drying defects, especially those characterized by warped and split wood. The different wood types present in the stem are related to the variation of these important physical properties. This work aimed to study the retratibily of seven eucalypt species. The retratibility parameters such as the variation in the pith to bark direction in the peripheral of the trunk were studied according the Brazilian Standard for the seven eucalypts. In general the results showed that the species of eucalypts studied have a high retratibility. Except for Eucalyptus tereticornis and E. pilularis the others species studied showed lower values of retratibility in the pith region.
