Advancing the tamarillo harvest by induced postharvest ripening.

Dark-red-, red- and yellow-type tamarillos were sorted into 2 maturity stages (green and turning), dipped in ethephon at 0, 250, 500 or 750 mg/litre and kept at 18 or 28 deg C. Seven days later, fruits dipped in ethephon at 500 or 750 mg/litre and stored at 28 deg showed a colour score, maturity index and ascorbic acid content similar to those tree-ripened, thus making it possible for harvesting to be advanced by 36 days. Under these conditions, weight loss was always <8.5%, resulting in only slight symptoms of shrivelling that did not affect commercial quality. Postharvest ripening reduces the risk of crop failure, increases earliness and concentrates harvesting time.
