Significant opportunities exist for expanding the marketing season of Louisiana-grown satsumas. De-greening of the early season fruit coupled with optimal storage conditions for the late season fruit may allow for 6 months of market availability. Consumer demand in the U.S. for specialty citrus, particularly easy peel seedless mandarins, has increased in recent years. South Louisiana is one of the principal satsuma production areas in the United States, with harvest beginning in late September. Although the sugar: acid ratio of early season satsumas may meet the state-mandated 10:1, peel color typically ranges from green to greenish-yellow. Most consumers prefer a darker yellow-orange peel color. Postharvest de-greening tests were conducted to determine the appropriate method(s) and protocol for enhancing peel coloration of early season harvested satsumas. Green peel satsuma fruit were exposed to 0, 3, 5, 10, and 50 ppm ethylene for 12, 24, 36, and 48 hours at 21 or 29 °C. An atmospheric ethylene concentration of ≥5 ppm for ≥24 hours at 29 °C provided optimal de-greening. However, peel darkening in the form of irregular dark brown areas was observed after several days in fruit exposed to ethylene concentrations of 50 ppm. Ethephon was also an effective de-greening agent. Submersion of the fruit in 500 ppm ethephon for 30 seconds provided optimal de-greening. Buffering of the submersion solution pH had no effect on de-greening effectiveness.
