摘要：

对缓慢降温处理后石榴果实在冷害温度下的生理反应进行了研究，旨在为石榴果实采后保鲜提供理论依据。以新疆大籽石榴为试材，研究了0℃低温胁迫及缓慢降温对石榴果实采后生理的影响结果表明，与0℃的低温相比，缓慢降温处理减缓石榴果皮细胞膜透性的升高以及膜脂质过氧化物丙二醛的积累,抑制了多酚氧化酶活性的增加及减少了酚类物质的氧化，明显推迟和减轻石榴果实冷害症状的发生，减轻了果皮的褐变，保持果实品质。

Abstract:

Physiological changes of the 0 ℃ low temperature stress and slow cooling treatment on chilling injury of the pomegranate fruit were studied. The results showed that the slow cooling treatment could lower the membrane permeability and reduce the accumulation of malondialdehyde (MDA) content ,inhibit the polyphenol oxidase activity and decrease the oxidation of phenolic substances of the pomegranate pericarp of stored at 0℃.The slow cooling treatment could postpone the symptom of chilling injury appearing and lighten the degree of chilling injury of pomegranate fruits and reduce pericarp browning and maintain fruit quality.
