| 摘 要： | 以新高梨为试材,果实经1-MCP(1-甲基环丙烯)处理再冷藏一定时间后,研究常温货架期间1-MCP对果实贮藏效果的影响.结果表明:1-MCP能明显抑制果实呼吸强度、乙烯释放量的升高,推迟呼吸高峰和乙烯高峰出现的时间;抑制了果实丙二醛(MDA)和果皮相对膜透性的升高;延缓了果实硬度、可滴定酸含量的下降,阻碍了可溶性固形物的上升,使果实的货架期明显延长,延缓了果心褐变,但却加速了果实的果皮褐变. |
| 关 键 词： | 新高梨 冷藏 硬度 呼吸强度 |

| Abstract: | The fruits of Niitaka pears were treated with 1-MCP(1-methylcycloproene) in low temperature,during storage at ambient temperature were studied.The results indicated that 1-MCP treatment made fruit could intensively inhibit the respiratory intensity and ethylene,postponed the appeared time of ethylene and the time of climacteric;1-MCP treatment also had a remarkable effect on the inhibition of the increase of MDA and membrane relative permeability;remain high quality and good flavor during storage by delaying the loss of firmness and titratable acid(TA),and inherent the increasing of total soluble solids(TSS),could control and postpone the shelf storage,postpone the browning of the core,but accelerate the browning of the peel. |
