Mature-green Japanese apricot (Mume, <I>Prunus mume</I> SIEB. et Zucc.) cv. Shirokaga was stored at 15°C by W-Step Modified Air System CA (MASCA), which was developed as an economical CA storage facility, and its efficiency for extension of shelf life of fruits was investigated. 1) The concentration of oxygen and carbon dioxide in the CA chamber was maintained within the range between 1.5 and 3.5% for oxygen and 3 and 5% for carbon dioxide, respectively. 2) As compared with the storage at 15°C under air, MASCA markedly reduced the rate of respiration. Evolution of ethylene was not observed during MASCA storage. A marked increase in respiration rate of MASCA-stored fruits was first detected on 6 days after removal from MASCA. Ethylene was evolved during climacteric rise and caused after-ripening. 3) MASCA well retained chlorophyll of fruits and their green color. 4) Neither browning or off-flavor nor chilling injury was observed. 5) MASCA retarded the metabolism of organic acids and sugars, but it affected little for the latter compounds. 6) As a result, MASCA was decidedly beneficial in retarding ripening of mature-green Japanese apricot fruits, and the MASCA-stored fruits were still in good condition for distribution.
