It was evaluated the physiological aspects of the cagaita (Eugenia dysenterica) development, from anthesis to ripening. The fruits have been subjected to physical and chemical analysis during the fruit life cycle. The total fruit development comprised 37days. There was a steady increase in the total mass of the fruits and significant increase in transverse and longitudinal diameter, adjusting the double sigmoidal behavior in response to changes in the time. From the 23rd DAA, it was observed the beginning of loss of firmness, increase in total and soluble pectin content and a decrease in starch content. It occurred degradation of total chlorophyll and unmasking of carotenoids from 31st days after anthesis. A decrease in pH and, therefore, increase in acidity, low soluble solids content. The sucrose content was extremely low during the cycle. At the end of development, the respiratory and ethylene production peak was observed, suggesting climacteric behavior.
