摘　　要：研究了40%、60%、80%和100% O2及空气气流连续处理对'Duke'蓝莓和'Allstar'草莓果实在5℃下35 d和14 d贮藏期间呼吸作用和乙烯产生的影响.结果表明,60%～100% O2处理显著抑制蓝莓果实的呼吸速率和乙烯释放速率,并且O2浓度越高,呼吸速率和乙烯释放速率越低,而40% O2对蓝莓果实呼吸速率和乙烯释放速率无显著影响.在贮藏前8 d,高氧处理对草莓果实呼吸速率和乙烯释放速率无显著影响,但在贮藏10～14 d,80%和100% O2处理的呼吸速率和乙烯释放速率显著低于对照和其它高氧处理.Freshly harvested blueberries （ Vaccinium corymbosum L. ‘Duke＇ ） and strawberries （ Fragaria ×ananassa Duch.‘ Allstar＇ ） were placed in jars and continuously ventilated with air or 40%, 60% , 80% or 100% O2 for 35 and 14 days at 5℃, respectively, to investigate effects of high oxygen atmospheres on fruit respiratory rate and ethylene production. While exposure of blueberries to 40% O2 slightly affected fruit respiratory rate and ethylene production, fruits exposed to 60% - 100% O2 exhibited significantly lower respiratory rate and ethylene production rate than those exposed to air. In strawberries, application of high oxygen atmospheres had no significant effects on fruit respiratory rate and ethylene production within 8 days of storage, but significantly lower respiratory rate and ethylene production rate were observed in fruits exposed to 80% and 100% O2 in the comparison with those exposed to other high O2 atmospheres and air between 10 and 14 days of storage.
