摘要: 乙醇处理红星苹果,降低了α-法尼稀的生成并阻止其氧化为共轭三烯,由此抑制了虎皮病的发生。18℃下,每千克苹果经2ml、4ml、6ml乙醇处理,密封于聚乙烯薄膜袋中(0.03mm),一周后于1℃冷库中贮藏。随着乙醇用量的增加,果实内的乙醇含量也增加,抑制乙烯生物合成的防治虎皮病的作用加大。高浓度乙醇处理(4ml/kg或6ml/kg)降低了虎皮病的发生率和发病指数。

Abstract: Studies on Red Star apples suggested that ethanol vapor treatment could controls superficial sacld by reducing the production of α-farnesene and preventing its breakdown to conjugated trienes.Ethanol at the concentration of 0,2,4,6 ml/kg apples was placed in dishes in polyethylene bags for apples.The bags were sealed and stored at 18℃ for a week,then the apples were stored at 1℃.There were close and highly significant inverse relationships bvetween the concentration of ethanol in the juice,etylene production and scald.Higher ethanol concentration (4ml/kg or 6ml/kg) treatment decreased the scald rate and incidence
