摘要
以泗洪大枣为试材,研究了低温条件下(1±1℃)安喜布(1-MCP)处理(10kg果实/片安喜布,1-MCP有效质量浓度为0.9mg/L)对其生理生化的影响。结果表明,10kg/片安喜布处理可以抑制枣果呼吸速率,贮藏15d和45d呼吸速率分别为对照的53%和50%;可以延缓果实硬度下降,减少枣果维生素C的损失,从而保持枣果采后品质。贮藏60d维生素C保存率高达84.3%,是同期对照果的2倍;降低枣果细胞膜透性,延缓果实的衰老;抑制果实腐烂,对照果实贮藏30d即出现腐烂,而安喜布处理的枣果贮藏60d才开始出现腐烂;安喜布处理对延缓枣果转红效果不明显。
Fruit of Sihongdazao jujube cultivar were treated with AnsiP-S（1-MCP） （ 10 kg fruit/chip, the effective comcentration of 1-MCP was 0.9 mg/L） for studying the effect on physiological and biochemical changes during cold storage （1±1 ℃）. The results indicated that AnsiP-S treatment inhibited the respiration rate. The respiration rate was 53% and 50% of the control respectively after stored for 15 and 45 days. It remained high quality by delaying the decline of firmness and decreasing the loss of the content of Vc. It was 2 times of the control and the preservation rate of Vc was 84.3% at 60 days during storage ; it delayed the fruit senescence by reducing the cell membrane permeability ; and it inhibited the fruit rot, while the fruit of control rotted at 30 days during storage but the fruit of AnsiP-S treatment rotted till 60 days during storage ; AnsiP-S treatment had on signifcant effects on the change of red colour.
