摘要

该研究以中华寿桃为试材,研究了1-甲基环丙烯(1-methylcyclopropene, 1-MCP)(1 mg/m3)处理、减压(0.05~0.06 MPa)处理以及减压结合1-MCP处理对中华寿桃的贮藏期及货架期果实冷害的影响,并从能量代谢的角度探讨了不同处理方法减轻桃果实冷害的机理。结果表明,减压结合1-MCP处理后的中华寿桃褐变程度最轻,不仅能保持果实较好的贮藏品质,而且能有效维持果实的货架品质。结合处理后的果实腺嘌呤核苷三磷酸(adenosine triphosphate, ATP)和二磷酸腺苷(adenosine diphosphate, ADP)含量高于其他处理,一磷酸腺苷(adenosine monophosphate, AMP)的增加受到抑制,琥珀酸脱氢酶(succinate dehydrogenase, SDH)和线粒体细胞色素C氧化酶(cytochrome C oxidase, CCO)活性下降变缓,减压结合1-MCP处理通过保证能量生成速率,为贮藏期和货架期的果实提供能量,减轻了果实的冷害,从而延长了果实的贮藏期和货架期。

Abstract

Using Prunus persica L. as test materials, this study investigated the effects of 1-methylcyclopropene(1-MCP) (1 mg/m3) treatment, hypobaric (0.05-0.06 MPa) treatment and hypobaric combined with 1-MCP treatment on the storage and shelf life of Prunus persica L.. Also, it explored the mechanism of different treatments to alleviate the chilling injury of peach fruit from the perspective of energy metabolism. The results showed that the hypobaric combined with 1-MCP treatment of Prunus persica L. had the least browning degree, which not only could maintain the better storage quality of the fruit, but also effectively maintain the shelf quality of the fruit. The combined treatment of adenosine triphosphate (ATP) and adenosine diphosphate (ADP) was higher than other treatments. The increase in adenosine monophosphate (AMP) was inhibited by the combined treatment. In addition, the combined treatment slowed declines of succinate dehydrogenase (SDH) and mitochondrial cytochrome C oxidase (CCO) activity. The results indicate that hypobaric combined with 1-MCP treatment provides energy for the storage and shelf life by ensuring the energy production rate, which reduces the chilling damage of the fruit, thereby prolongs the storage period and shelf life of the fruit.
