Abstract
【Objective】This study aimed to determine the effects of 1-methylcyclopropene(1-MCP)on chilling injury and storage quality of‘Xuxiang'kiwifruit and to improve the storage qulity of kiwifruit after harvest.【Method】‘Xuxiang'kiwifruits were chosen as the study material.The fruits were treated by0.5μL/L 1-MCP for 24hour before being stored at temperature of 0℃for 90days.Fruits treated by distilled water were set as control.The chilling injury index,chilling incidence,respiration rate,ethylene production rate,soluble solid content,titratable acidity content,firmness,membrane permeability,MDA content,weight loss rate and rotting rate per 10days were measured and analyzed.【Result】Treatment with0.5μL/L 1-MCP significantly delayed and reduced the chilling injury of kiwifruit.Fruits treated by 1-MCP experienced chilling injury 20days later than the control,and their chilling injury incidences were 32.35%of control.1-MCP significantly inhibited the increase of membrane permeability and MDA content at later storage period.Fruits reached the respiration climax after 10days,and the respiration rates of 1-MCP treatment and the control were 7.25mg/(kg·h)and 7.98mg/(kg·h),respectively.The ethylene climax appeared after 60days storage,and the ethylene production rates of 1-MCP treatment and the control were0.016μL/(kg·h)and 0.048μL/(kg·h),respectively.1-MCP markedly delayed the decrease of firmness and titratable acidity,but had no effects on soluble solid content.After 90days storage,the weight loss rates of 1-MCP treatment and the control were 0.603% and 0.278%,and the rotting rate of them were10.3%and 2.7%,respectively.【Conclusion】Treatment with 0.5μL/L 1-MCP significantly reduced chilling injury of‘Xuxiang'kiwifruit,and maintained higher fruit quality.
