This study investigated the potential of delaying 1-methylcyclopropene (1-MCP) application as a postharvest strategy to enhance ripening recovery of banana fruit。 The experiment comprised the following treatments: control (no 1-MCP)， 400 nL L-1 1-MCP at 1 and 15 d， and 50 mu L L-1 ethephon + 400 nL L-1 at 1 and 15 d， arranged in a completely randomized design。 Fruit were stored at 14 degrees C for 30 d and thereafter allowed to ripen at 23 degrees C for 9 d。 After 9 d shelf life， 1-MCP/15 d treated fruit had significantly lower firmness (54。24 N) compared to fruit treated with 1-MCP/1 d (69。45 N)。 Peel degreening was significantly higher in the 1-MCP/1 d treatment， with hue values of 92。06 compared to 86。62 for 1-MCP/15 d。 The 1-MCP/1 d treatment significantly maintained higher total chlorophyll (307。7 mu g/g) and carotenoids (145 mu g/g) in peel compared to 1-MCP/15 d treatment。 Sucrose accumulation significantly increased in 1-MCP/15 d treated fruit (5。26 mg/mL) compared to that treated with 1-MCP/1 d (1。74 mg/mL)。 A similar trend was observed for glucose (0。81 mg/mL) and fructose (0。83 mg/mL)。 The 1-MCP/1 d treated fruit had no detectable glucose and fructose during shelf life。 Our results demonstrated that application of 1-MCP at 15 d cold storage is a promising postharvest strategy to extend fruit shelf life by enhancing ripening recovery after cold storage。
