2002
Jeong, Jiwon | Huber, Donald J. | Sargent, Steven A. | Crane, Jonathan H.
A series of experiments were performed to determine the effects of postharvest application of ethylene on ripening uniformity and fruit quality of a late-season, West Indian-type avocado ('Monroe'). Fruit from three harvest dates (early, mid- and late season) were treated with ethylene (100 ppm) at 13 or 20°C for 12 or 24 hours, or held continuously in air at 13°C, Avocados treated with ethylene (100 ppm) at 13°C for 24 hours ripened more uniformly and had lower incidence of decay than those from the other treatments. Uniform ripening was defined as fruit within a given lot with less variability in firmness at the full-ripe stage, Fruit from all treatments exhibited no significant differences in peel color, dry matter, or oil content during ripening.
