摘要:

【目的】研究NO减压熏蒸对甜瓜果实采后衰老的抑制作用。【方法】以新疆特色品种西州密17号为研究试材,在20KPa压力条件下,采用60μL/L的NO进行熏蒸处理,分析贮藏品质及活性氧代谢相关酶活性,探讨果实衰老进程与活性代谢之间的相关性。【结果】20 KPa+60 μL/LNO熏蒸处理为最适宜的熏蒸方式,有效延缓了果实的硬度下降;降低了果实的失重率与腐烂率;延缓了果实可溶性固形物、可滴定酸的降低;显著抑制了呼吸强度、电导率和丙二醛的上升;维持了果实过氧化物酶(POD)、过氧化氢酶(CAT)和超氧化物歧化酶(SOD)的活性(67.36%、69.96%、34.34%),维持了超氧阴离子、过氧化氢的清除能力。【结论】NO结合减压熏蒸处理可以有效地提高抗氧化酶活性减少甜瓜果实采后活性氧代谢的积累,减轻了果实的氧化损伤,延缓果实品质劣变进程。

Abstract:

【Objective】 To investigate the inhibitory impact of hypobaric treatment combined with NO fumigation on the postharvest senescence of cantaloupe.【Methods】 The Xinjiang characteristic variety, Xizhoumi 17 was chosen as the experimental material. A concentration of 60 μL/L of NO was used for fumigation treatment under pressure of 20 KPa. The postharvest quality and enzyme activities associated with reactive oxygen species metabolism (ROS) were analyzed, aiming to explore the relationship between fruit senescence progression and ROS metabolism.【Results】 The fumigation treatment of 20 KPa + 60 μL/L NO was the most suitable fumigation method, which effectively delayed the decrease of fruit firmness; reduced the weight loss and decay rate of fruit; delayed the decrease of fruit soluble solids and titratable acid; significantly inhibited the increase of respiration intensity, conductivity and malondialdehyde; maintained the activities of peroxidase (POD), catalase (CAT) and superoxide dismutase (SOD) (67.36%, 69.96%, 34.34%), and consequently maintained the scavenging capacity of superoxide anion and hydrogen peroxide (SOD) activities (67.36%, 69.96%, and 34.34%), which in turn maintained the scavenging capacity of superoxide anion and hydrogen peroxide.【Conclusion】 Hypobaric treatment combined with NO fumigation effectively enhances the activities of antioxidant enzymes and alleviate the accumulation of reactive oxygen species in cantaloupe. This reduction in oxidative damage prolonged the postharvest quality and preservation of the fruit.
