The objective of this work was to evaluate the fruit development of Ponkan mandarin (Citrus reticulata Blanco). Fruit development followed a simple sigmoid curve, with phase I extending from anthesis to the 85th day after full flowering, with a transition period to phase II that lasted up to the 101st day after full flowering. Phase II began soon after the transition phase, extending up to the 251st day after full flowering. Phase III, fruit ripening, began at the 251st day after full flowering and it was prolonged until harvest, which was carried out at the 276th day after full flowering.
