The efficience of nutrients absortion by the fruits can be influenced by the morphological structures of the pericarp. The present research aimed to describe the pericarp morphology of guava fruits, considering the importance of this information to proceed an adequate management in leaf adubation or post harvest treatments to increase fruit's lifetime in guava orchards. The guava fruits (cv. Paluma) pericarp samples were evaluated under optical and scanning electron microscopy. Some of the characteristics observed were the thick cuticle, epicuticular wax, three sub-epidermical layers of compact cells and a high amount of esclerídeos. These characteristics can be considered barriers for absortion and movement of substances in guava fruits.
