Effects of treatment with 1 μL/L,5 μL/L or 50 μL/L 1-methylcyclopropene(1-MCP) or 1-oectylcyclopropene(1-OCP) on postharvest physiology and quality of green mature mango(Mangifera indica L.) fruits stored at ambient temperature(20±2℃) were investigated.The results showed that all the treatments slowed down the decline of fruit firmness,delayed respiratory peak time for 3 days compared to the control,reduced the rise of SSC,decreased the titratable acid and MDA content,inhibited POD and PPO activity as well as the weight loss and maturation process.However,treatment with 5 μL/L 1-MCP or 50 μL/L 1-OCP showed better effect than other concentrations.It is suggested that these two concentrations are better in controlling ethylene action of mango fruit during postharvest storage.
