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。

Abstract: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 p roduction rate than those exposed to air. In strawberries, application of high oxygen atmospheres had no significant effects on fruit respiratory rate and ethylene p roduction within 8 days of storage, but significantly lower respiratory rate and ethylene p roduction 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.
