Abstract

Abstract:

Effects of 1-MCP on expression of ethylene receptor Le2ETR4 and ethylene production rate in harvested cherry tomato (Lycopersicon esculentum ) fruit at different maturation stages were investigated in this study. 1-MCP treatment reduced Le2ETR4 expression and ethylene production rate of turning fruit, and inhibited the Le2ETR4 expression of green mature and pink fruit at 20℃. However, 1-MCP treatment had no significant influence on ethylene production rate of green mature and pink fruit at 20℃. Furthermore, 1-MCP treatment accelerated ethylene production rate but had no obvious effect on the Le2ETR4 expression in red ripe fruit.
