乙烯会加速贮藏果蔬变质,除去乙烯能提高多种果蔬的贮藏效果。温度对低乙烯效应有明显影响。如在20℃的低乙烯气体中贮藏香蕉,其贮藏寿命能成倍增加;但在3℃时,低乙烯对苹果贮藏效果的影响不明显。贮藏蔬菜(如石刁柏、葫萝卜、甘薯)时,乙烯还能提高酚代谢中一种重要的酶——苯丙氨酸铵裂解酶的活性,从而累积了激发多酚氧化酶活性或作为木质素合成基质的酚中间产物,而
Ethylene will accelerate the deterioration of storage of fruits and vegetables, remove ethylene can improve the storage of a variety of fruits and vegetables. Temperature has a significant effect on the low ethylene effect. For example, the storage life of banana in low ethylene gas at 20 ℃ can be doubled. But at 3 ℃, the effect of low ethylene on the storage of apple is not obvious. When stored in vegetables (eg, asparagus, cucurbits, sweet potatoes), ethylene also increases the activity of an enzyme, phenylalanine ammonia lyase, which is an important enzyme in the metabolism of phenols, thereby accumulating activity that activates polyphenol oxidase or Lignin synthesis matrix phenol intermediate, and
