Abstract
In order to determine the effectiveness of 1-methylcyclopropene(1-MCP)on chilling injury and disease resistance of tomato fruit after cold storage.Green mature 'Zheza 205' tomato fruit was treated by 1 μL · L-1 1-MCP before being stored at 3 ℃ for 14 days then ripen at 20 ℃ for 16 days.The quality and physiology of tomato fruit were investigated.1-MCP treatment not only promoted chilling injury and disease index,but also increased the activities of polyphenol oxidase and peroxidase.1-MCP treatment retarded the peak of ethylene and the increase of lycopene,maintained higher content of titratable acidity and firmness.The activities of chitinase and β-1,3-glucanase were also inhibited by 1-MCP treatment.This study indicated that 1 μL · L-1 1-MCP delayed tomato fruit ripen,but promoted chilling injury and disease incidence,and showed that it could not be considered for commercial use in tomato fruit after cold storage.
