The work aims to study the effects of different treatments on storage quality of Red Peach in order to provide new path for its postharvest storage technique. Red Peach was used as research material to study the effects of 4 treatments (CK, control treatment; S1, ethylene adsorbent; S2, 1-MCP; S3, calcium chloride) on physiological, nutritional and enzymatic indices at (5±0.5) ℃. From comprehensive comparison, treatment with ethylene adsorbent could better reduce the decay rate of fruit, inhibit the increase of respiration intensity and ethylene production rate, delay the decline of hardness, soluble solids content and titratable acid content, and maintain the activities of superoxide dismutase (SOD), catalase (CAT), ascorbic acid peroxidase (APX), peroxidase (POD) and polyphenol oxidase (PPO) of the Red Peach. The Red Peach treated by ethylene adsorbent after postharvest has the best storage effect, which can maintain its high storage quality.
