صينى. 为了找到适合草莓果实贮藏的气调模式，研究了自发气调和氮气气调处理对果实保鲜的效应。结果表明，自发气调处理（MA）和氮气气调处理（NA）均对草莓果实的呼吸有抑制作用，贮藏108h后MA和NA处理的果实呼吸速率分别为对照的62%和52%。同时，气调处理也降低了草莓果实的腐烂指数和失重率，贮藏108h后MA处理的果实腐烂指数为对照的38%，NA处理无腐烂，失重率分别为对照的8.0%和0.3%。并且气调处理维持了果实较高的超氧化物歧化酶（SOD）活性，抑制了抗坏血酸过氧化物酶（APX）活性和纤维素酶（Cel）活性，降低了超氧阴离子（O2. ）产生速率和丙二醛（MDA）含量，有利于保持果实品质。[著者文摘]

The resuhs showed that the treatments depressed the fruit respiration, which treated with MA and NA were 62% and 52% of that of the control, respectively, ＂after storage for 108 h. They also redueed the decay rate and water loss. The decay rate with MA was 38% of that of the control after 108 h storage, whereas no decayed fruits were found in NA treatment. The water loss rales of MA and NA treatments were 8. 0% and 0. 3%, respectively, compared with the control. It also maintained higher level of superoxidate dismutase （SOD） activity, and simuhaneously suppressed the activities of aseorbate peroxidase （APX） and eellulase （Cel）, the O2. production rate and the malonaldehvde content. Therefore, the controlled atmosphere storages may be used to preserve quality of the fruits.
