This work was carried out to evaluate the development of longan (Dimocarpus longan Lour) fruits in the region of Jaboticabal, and establish the fruit growth curve. Weekly evaluations were performed to measure longitudinal and transversal diameter of selected fruits after pulp formation. Every two weeks, physical and chemical parameters were evaluated: fruit, peel, pulp and seed mass (g); titrable acidity (TA), soluble solids (SS), ascorbic acid (AA) and the ratio (SS/TA). Results indicate that longan reproductive cycle in the region is 120 to 130 days after anthesis, period after which the fruit is good for consumption, when the fruit development curve follows a simple sigmoidal pattern. Physical and chemical parameters have shown that the longan fruits analyzed here have a high consumption potential.
