【摘要】 两种蝇蛆几丁低聚糖对7种草菌病原菌的抑制作用,试验结果表明酶解几丁低聚精的抑菌活性显著高于H₂O₂水解几丁低聚糖,质量浓度10g/ml时,它对草莓灰霉菌等6种病原菌有强烈的抑制作用,抑菌效果在80％以上,但对草莓白粉菌的抑制作用一般;H₂O₂水解几丁低聚糖对草莓灰霉菌等4种病原菌也有很好的抑制效果,对草莓黑霉病菌等3种病原菌的抑制作用较差。盆栽试验结果表明蝇蛆几丁低聚糖喷雾处理可以减少生长期草莓果实的发病率,处理后第3天即表现出一定的防病效果,处理后第6天防病效果最佳,处理后第9天,防病效果开始有所下降。涂膜处理试验结果表明,在常温下,10～20mg/ml几丁低聚糖溶液处理,可使草莓的保存期延长2～3天。更多还原

【Abstract】 Under greenhouse conditions, Chitooligosaccharides from housefly larvae (Musca domes-tica vicina Macquart) have good inhibition against 6 kinds of strawberry fruit fungi at 10mg/ml. Pot culture showed that chitooligosaccharides can decrease the incidence of strawberry fruit in development stages in greenhouse. When Chitooligosaccharides is used to preserve strawberry fruit, it can extend the storage duration of strawberry fruit for 2 to 3 days during storage at atmosphere temperature.更多还原
