摘要
研究了3种含量(1,5,50μL/L)的环丙烯类乙烯效应抑制剂1-OCP在常温(20±2)℃条件下熏蒸处理20h对青熟期芒果贮藏保鲜效果的影响。试验结果表明:3种含量的1-OCP处理均能延缓果实的后熟,其中50μL/L 1-OCP处理的芒果保鲜效果最好。贮藏第13天时,50μL/L 1-OCP处理的果实SSC含量和失重率分别比对照低4.4%和0.79%,果实硬度高于对照51%,MDA含量仅为对照的43.1%;POD,PPO活性高峰和呼吸高峰较对照均有所减弱,峰值分别仅为对照峰值的89%,67%,75.1%,呼吸高峰的出现也延迟了3 d。由此说明1-OCP能够有效地抑制芒果果实贮藏期间品质的下降,可作为乙烯效应抑制剂,应用于呼吸跃变型果蔬的贮藏保鲜。
Effect of fumigating with 1, 5 or 50 μL/L 1-oectylcyclopropene(1-OCP) for 20 h on postharvest physiology and quality of green mature mango(Mangifera indica L.) fruits stored in ambient temperature(20±2) ℃ were investigated. The results show that all the treatments delayed fruit quality decrease and fruit senescence. However, treatment with 50 μl/L 1-OCP showed better effect than others. After storage for 13 d, the weight-loss rate and SSC of fruits treated with 50 μl/L 1-OCP were 0.79% and 4.4% lower, respectively, while fruit firmness was 51.0% higher, and MDA content was 43.1% lower than control; The peak of POD and PPO activities and respiratory peak were 89%, 67% and75.1% lower, respectively, and the occurrence of respiratory peak was delayed for 3 d compared to the control. The results indicate that 1-OCP can be a candidate to control ethylene action of mango fruit during postharvest storage for agricultural practice.
