Abstract: Tomato fruits treated by different concentrations ethephon and 1-MCP were measured to reveal cold tolerance of tomato fruits induced by ethylene. The results indicated that when exogenous ethephon concentration is 0.04%, free proline content and cell water-holding capacity increase, but MDA content, relative ratio of electrolyte leakage and cell membrane lipid peroxidation decrease. 1-MCP treatment shows different effects. It is concluded that ethylene can improve cold tolerance, but 1-MCP can accelerate development of chilling injury. Endogenous ethephon can improve cold tolerance of tomato, which can be intensified by exogenous ethylene with suitable concentration.

Key words: ethylene, 1-MCP, cold tolerance, tomato
