- 摘要:
- 以‘美人椒’为试材，采用褪黑素浸泡和1-MCP熏蒸的方法，设置清水、100 μmol·L-1褪黑素、1 μL·L-1 1-MCP及100 μmol·L-1褪黑素复配1 μL·L-1 1-MCP 4种不同处理，在4 ℃和25 ℃条件下，于0、3、6、9、12、15 d取样，分别测定辣椒外观品质和内在品质的相关指标，筛选出缓解辣椒采后冷害、提升保鲜效果的最优处理方式，以期为提升辣椒贮藏品质提供参考依据。结果表明：在4 ℃下，褪黑素和1-MCP复配处理的相关指标均优于其他处理，保鲜效果最佳。贮藏至15 d时，清水处理的冷害指数最高为0.220，而褪黑素和1-MCP复配处理后，冷害指数为0.087，减少了60.45%，经外源褪黑素和1-MCP复配处理可以有效缓解辣椒采后冷害，提高辣椒果实品质。
- Abstract:
- Taking ‘Meiren Pepper’ as the test material，four different treatments of water，100 μmol·L-1 melatonin，1 μL·L-1 1-MCP and 100 μmol·L-1 melatonin combined with 1 μL·L-1 1-MCP were set up by melatonin soaking and 1-MCP fumigation.Samples were taken at 0，3，6，9，12 days and 15 days at 4 ℃ and 25 ℃，and the related indexes of appearance quality and internal quality of pepper were determined respectively，in order to screen out the optimal treatment method to alleviate the chilling injury and improve the preservation effect of pepper after harvest and provide reference for improving the storage quality of peppers.The results showed that at 4 ℃，the related indexes of the combined treatment group of melatonin and 1-MCP were better than other treatments，and the preservation effect was the best.When the pepper was stored for 15 days，the chilling injury index of the water treatment group was the highest，0.220，while the chilling injury index of the combined treatment of melatonin and 1-MCP was 0.087，which was reduced by 60.45%.The combined treatment of exogenous melatonin and 1-MCP could effectively alleviate the postharvest chilling injury of pepper and improve the quality of pepper fruit.
