| 摘要: |
| 【目的】 研究1 甲基环丙烯（1-MCP）和温度处理对‘秦阳’苹果采后生理和品质的影响，为其采后贮藏提供理论依据。【方法】 以‘秦阳’苹果为试材，在0和20 ℃ 2种贮藏温度下,研究了0.5 μL/L 1-MCP密封24 h处理对‘秦阳’苹果呼吸速率、乙烯生成速率及品质的影响。【结果】 0和20 ℃贮藏温度下，0.5 μL/L 1-MCP处理均能显著降低‘秦阳’苹果的呼吸速率和乙烯生成速率，延缓果实软化，保持可滴定酸含量，但以0 ℃下的贮藏效果较好。0 ℃贮藏期间，果实的呼吸速率最高为7.3 mg/(kg·h)，乙烯生成速率几乎为0，对可溶性固形物含量无明显影响。【结论】 0.5 μL/L 1-MCP处理明显降低了‘秦阳’苹果的呼吸速率和乙烯生成速率，延缓了果实品质的下降。 |

| 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. |
