Abstract

【Objective】 The study was to investigate the effect of 0.5 μL/L 1-MCP on quality and postharvest physilogy of Qinyang Apple and primary theory for storage.【Method】 0.5 μ L/L 1-MCP treatment on respiration rate,ethylene production rate and fruit quality of Qinyang Apple was studied at 0 and 20 ℃.【Result】 Both 0 ℃ and 20 ℃ 0.5 μL/L 1-MCP treatment can significantly reduce the respiration rate and ethylene production rate of Qinyang Apple,slow down the softening of fruit,maintain titratable acid content,especially storaged at 0 ℃.The highest respiration rate is 7.3 mg/(kg·h) and the ethylene production rate is almost 0,but the total soluable solids have no significant effect.【Conclusion】 0.5 μL/L 1-MCP treatment can significantly reduce the respiration,ethylene production rate of Qinyang Apple fruit,and slow the decline in fruit quality.
