摘要 'Andesu' 网状瓜果 (Cucumismelo. L.) 在 35 至 47 DAA 期间用纯氮气或空气通风 12 天，在 47 至 53 DAA 期间通风 6 天（分别为成熟和过熟阶段）。与通风的果实相比，暴露于厌氧氮气气氛导致中果皮中乙醛和乙醇浓度较高，而蔗糖浓度较低。然而，在厌氧氮气氛下并没有出现水浸症状，表明水浸中果皮组织的形成不是由于酒精发酵增加和/或果肉中可溶性糖积累减少所致。厌氧氮气氛还导致乙烯产量低、果肉硬度高，并抑制细胞壁中多糖醛酸和非纤维素中性糖的解聚。提出了细胞间隙和膜通透性增加对水浸症状发生的重要性。
Abstract'Andesu' netted melon fruits (Cucumismelo. L.) were ventilated with pure nitrogen or air for 12 days from35 to 47 DAA or 6 days from 47 to 53 DAA (ripe and over-ripe stages,respectively). Exposure to anaerobic nitrogen atmosphere resulted in higheracetaldehyde and ethanol concentrations, while lower sucrose concentration wasrecorded in the mesocarp compared with air-ventilated fruit. However,water-soaked symptom was not developed under anaerobic nitrogen atmospheres,suggesting that the formation of water-soaking mesocarp tissue does not resultfrom increased alcoholic fermentation and/or decreased soluble sugaraccumulation in the flesh. Anaerobic nitrogen atmospheres also resulted in lowethylene production, high flesh firmness, and inhibition of depolymerisation ofpolyuronides and non-cellulosic neutral sugars in the cell walls. Theimportanceof increased intercellular spaces and membrane permeability on the developmentof water-soaked symptom was suggested.
