以内蒙古巴盟磴口县河套蜜瓜为试材，研究了河套蜜瓜成熟衰老过程中淀粉酶、过氧化氢酶、乙烯、果胶含量以及呼吸强度的变化特点，结果表明，河套蜜瓜是典型的呼吸跃变型果实，与成熟密切相关的物质代谢与呼吸代谢的酶最早出现的高峰期是淀粉酶在开花座果后２７ｄ，过氧化氢酶在开花座果后２０ｄ，随后出现物质代谢和呼吸代谢高峰。乙烯含量第１次高峰出现在开花座果２７ｄ时，促进果实成熟，采后７ｄ出现第２次高峰，此时果实开始腐烂。
In order to study the changes of amylase, catalase, ethylene, pectin and respiration rate during the aging process of honeydew melon in Hetao, the results showed that the changes of respiration rate in the honeydew melon The typical climacteric fruit, mature and closely related to the metabolism and respiratory metabolism of the earliest peak of the enzyme is the amylase after flowering in the first 27d, catalase after flowering in the fruit 20d, followed by material metabolism and Respiratory metabolism peak. The first peak of ethylene content appeared on the flowering fruit 27d, promoting fruit ripening, and the second peak occurred on the 7th day after harvest, when the fruit began to decay.
