摘　　要：在(-1±0.5)℃的条件下,以常压贮藏为对照,进行金铃大枣的减压贮藏实验。在贮藏过程中,测定了枣果的VC含量、可溶性固形物(TSS)含量、多聚半乳糖醛酸酶(PG)活性、丙二醛(MDA)含量及相对电导率,研究了减压贮藏对枣果生理生化变化的影响。结果表明,减压贮藏可以显著抑制枣果的成熟和衰老,但对保持枣果VC含量的效果不显著。The effect of hypobaric storage on physiological and biochemical of Jinling big jujube,such as the content of Vc,soluble solids content,polygalacturonase activity,malonyldildehye content and relative electric conductivity.The results showed that hypobaric storage can obviously keep the freshness of Jinling big jujube.But the effect of maintaining the content of Vc is not significant.
