摘要: 以樱桃番茄(Lycopersicon esculentum ) 品种‘卡罗’果实为材料, 研究了1-MCP处理对不同成熟度果实采后20℃贮藏过程中乙烯受体Le2ETR4表达和乙烯释放水平的影响。结果表明: 1-MCP处理可以抑制跃变上升期(破色期) 番茄果实乙烯释放及Le2ETR4表达; 对跃变前期(绿熟) 和跃变高峰期(粉红期) 果实Le2ETR4表达也有抑制作用, 但对乙烯释放无明显影响; 对跃变下降期(红熟期) 果实Le2ETR4表达不仅无明显影响, 反而促进了乙烯释放。

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.
