Abstract

In order to explore the effects of different concentrations of ozone treatment on the storage quality and ethylene synthesis of postharvest prunes, this experiment selected (0, 64.2, 96.3, 128.4 mg/m3) concentrations of ozone, and treated prunes every 15 days.The fruits were stored at near-ice temperature (-1--1.5 ℃) and relative humidity (80%-90%), and the storage quality and ethylene synthesis metabolism indexes of prunes were determined.The results showed that different concentrations of ozone treatment could inhibit the respiration rate of prunes, delay the decrease of fruit hardness and weight loss rate, and maintain the content of total soluble solids, titratable acidity and ascorbic acid.Among them, 96.3 mg/m3 ozone treatment had the best preservation effect on prunes.Further studies showed that 96.3 mg/m3 ozone group could inhibit the activity of 1-aminocyclopropane-1-carboxylic acid (ACC) synthase and ACC oxidase the key rate-limiting enzymes in ethylene synthesis, and reduce the conversion of Methionine and S-adenosyl methionine, the precursors of ethylene synthesis.It reduced the production of ACC and ethylene, and enhanced the antioxidant capacity of fruits.The results showed that ozone treatment could prolong the storage period of prunes by maintaining the storage quality of prune and inhibiting the synthesis of endogenous.
