Abstract: Experiment was conducted with sweetsop cultivar“ African Pride”(Annona squamosa L. cv. African Pride). The fruits were fumigated with 1.8μl/L 1-MCP (1-methylcyclopropene) for 17 hours at 25 ℃ and then stored at 15 ℃. The effects of 1-MCP treatment on storage quality and physiological changes of sweetsop fruits during cold storage were investigated. The results showed that 1-MCP treatment can increase significantly the rate of good fruits, delay the increase of TSS content in early storage and delay the ripening and softening of sweetsop fruits, 1-MCP treatment also can inhibit significantly the loss of VC content (p<0.01), and inhance the activities of SOD, POD and CAT in sweetsop fruits in late storage. In addition, 1-MCP treatment can decrease PPO activity and MDA content.
