Abstract

Longan (Dimocarpus longan Lour.) fruit cv. Daw harvested at the commercial stage were enclosed in controlled atmosphere (CA) chambers ventilated with 2 or 4% O2 combined with 5 and 15% CO2 (balance N2) or air (control) at 4ฐC and 95% relative humidity. The changes in respiration, ethylene production and weight loss were evaluated at 5 day interval. CA-stored fruits had lower rates of respiration than those fruits stored in air throughout storage. CA totally inhibited the rise in ethylene production as manifested by fruits in normal atmosphere. CA also reduced weight loss, with the CO2 level exerting a more dominant effect than low O2ทOf the atmospheres applied, the combination of 2% O 2 and 15% CO2 had the greatest impact at reducing respiration, ethylene production and weight loss.
