Effects of storage temperature and 1-methylcyclopropene on browning of Sichuan Prunus americana

Research of temperature and 1-methylcyclopropene (1-MCP) treatment on browning of Sichuan Prunus americana was showed in this paper. The Postharvest Prunus americana had been disposed by 1-MCP in 0.5 and 1.0μL/L respectively. Then the fruit which was disposed by 0.5μL/L 1-MCP had been stored in (0±0.5) ℃ and (10±0.5) ℃ respectively, and the fruit which disposed by 1.0μL/L 1-MCP had been stored in same two temperature respectively. Results showed that, low storage temperature on postharvest browning of Prunus americana had been obviously inhibited. And during the whole storage, 1-MCP treatment could effectively reduce the respiration rate and ethylene release rate (p<0.05) , maintain phenols content (p<0.05) , inhibit the polyphenoloxidase activity ( p < 0. 05) and malondialdehyde accumulation ( p < 0. 05) . Stored in (0±0.5) ℃ after treated by 0.5μL/L 1-MCP, the storage period of Prunus americana was extended to 72d, and its browning index was 7.13 that was minimum, and the quality of it was the best.
