With the objective to verify the photosynthate partitioning in roots and canopy of peache trees, two intensity of green pruning: light pruning and renovation pruning (heavy pruning). After fruit harvest were evaluated in 'Ouromel-2' peach in Piracicaba-SP. The carbohydrates levels of roots and canopy were evaluated in several phonological stages of the tree during the crop cycle. It was verified that there is a phase of consumption of carbohydrates, from dormant pruning to the ripening of fruits, and a phase of accumulation of carbohydrates, from the ripening of fruits to the falling of the leaves. In general, plants lightly pruned showed higher levels of carbohydrates during the crop cycle if compared to heavily pruned plants, showing then, higher potential of production.
