| 摘 要： | 以天水花牛苹果为实验材料,研究了1-甲基环丙烯（1-MCP）处理对花牛苹果在冷藏（0±0.5）℃及冷藏8个月后模拟货架10 d（25℃）期间虎皮病发生及相关生理生化指标的影响。结果表明:1-MCP处理可有效抑制苹果呼吸强度和乙烯释放量,推迟乙烯释放高峰的出现,降低α-法尼烯、共轭三烯含量,抑制α-法尼烯向共轭三烯的转化,同时1-MCP处理有效提高了花牛苹果果皮中内源抗氧化物质和总酚含量,抑制了多酚氧化酶（PPO）的活性,从而控制虎皮病的发生,降低了花牛苹果虎皮病的发病率和病情指数。

| Abstract: | The effect of 1- methylcyclopropene( 1- MCP) on superficial scald and postharvest physiology of‘Huaniu'apples were investigated,with 1-MCP treatment in the cold storage( 0 ± 0.5) ℃ and Shelf 10 days after the cold strorage for 8 months( 25℃). The results showed that: 1- MCP treatment could effectively decrease the respiration rate and the ethylene production,delaye the peak of ethylene,decrease the content of the a- farnesene and conjugated trienes,inhibite the conversion of a- farnesene to conjugated trienes; while 1- MCP treatment could also effectively improve the content of endogenous antioxidants and total phenol,inhibite the activity of polyphenoloxidase( PPO),so that 1- MCP controlled the incidence of superficial scald rate and reduced disease in‘Huaniu'apples. |
