不同浓度臭氧水对苹果轮纹菌的杀灭效果

Sterilizing Effect on Botryosphaeria berengriana in Apple Fruit by the Treatment with Ozone Water

以致使贮藏苹果腐败的主要真菌苹果轮纹菌为研究对象,通过离体和载体试验研究了不同浓度臭氧水处理对苹果轮纹病菌的杀灭效果。研究结果表明,离体试验中,不同浓度臭氧水对苹果轮纹病菌均有一定杀灭效果,其中浓度为1.2mg/L的臭氧水对苹果轮纹菌作用5min后的杀菌率可达80.96%;载体试验中,浓度为1.2mg/L臭氧水处理可显著抑制该病菌在苹果果实上的发病率和病斑直径的扩展。

The sterilizing effect of ozone water on decay-causing fungi of apple fruit,which contained Botryosphaeria berengriana,were investigated by in vitro and in vivo test.Results indicated that different concentrations of ozone water had some sterilizing effects on B.berengriana in vitro test.At the same time,under the conditions of sterilization time 5 min and the 80.96% bactericidal rate to B.berengriana can be achieved at the concentration of ozone water 1.2 mg/L.The vivo test results indicated that 1.2 mg/L ozone water had an inhibit effect to B.berengriana.
