Effect of treatment with different concentrations of 1-PentCP on physiological quality of mango fruit stored in ambient temperature

Effect of treatment with 1,5,50μL/L 1-pentylcyclopropene(1-PentCP) on postharvest physiology and quality of green mature mango (Mangifera indica L.) fruits stored 20h in ambient temperature (20±2)℃ were investigated. Results showed that all the treatments slowed down the decline of fruit firmness,delayed the occurrence time of respiratory peak for 3d compared with the control,reduced the rise of SSC and MDA content,decreased the titratable acid,inhibited POD and PPO activities. It was suggested that 1-PentCP could be candidates to control ethylene action of mango fruit during postharvest storage for agricultural practice. Treatment effect with 50μL/L 1-PentCP was better than others.
