摘要
为研究ClO2处理对采后甜樱桃果实病害抑制效果与品质的影响,本试验分别采用20、30、50 mg/L的ClO2溶液浸泡处理甜樱桃3 min,晾干后接种青霉菌和灰霉菌,将接种果实置于0±1℃温度下贮藏,分析测定贮藏期间果实病斑面积及多酚氧化酶(PPO)和过氧化物酶(POD)活性。结果表明,ClO2能够抑制青霉菌和灰霉菌发病程度,还可显著提高PPO和POD酶活性,延长甜樱桃贮藏期。
In order to study the effects of ClO 2 on inhibiting postharvest diseases and quality of sweet cherry, the fruits were soaked in 20, 30 and 50 mg/L ClO2 for 3 minutes respectively .After dried, the fruits were inoculated with penicillium and Botrytis allill.The inoculated fruits were stored at 0 ＆#177;1℃,and the dis-ease spot area on fruits was determined , as well as polyphenol oxidase （ PPO） and peroxidase （ POD） activi-ties.The results showed that ClO 2 could inhibit the occurrence of penicilliosis and gray mold ,and increase the activities of PPO and POD significantly , so the storage period could be prolonged .
