摘要: 本文采用了高效液相色谱(HPLC)法测定柰李果实四种内源激素(IAA,GA3,ABA,ZR)含量。通过比较了不同冷冲击处理对内源激素的影响以及贮藏过程中激素的变化,并结合冷藏过程中冷害发生情况,初步探讨了各处理在冷藏过程中内源激素变化的规律及其与柰李果实抗冷性的影响。此外,通过SDS-PAGE法分析蛋白质,结果表明,冷冲击处理能延缓柰李果实冷藏期的蛋白质降解,提高柰李果实的抗冷性。

Abstract: High performance liquid chromatography (HPLC) was used to detect endogenous phytohormones (IAA, GA3, ABA, ZR) of Nai-plum fruits (Prunussalicina Lindl.Var.cordata). Through comparing the variations of their contents after different cold shock treatments and the chilling injuries (CI), the regularity of phytohormone variations and the relationship between phytohormones level and the chilling tolerance of Nai-plum fruits during the cold storage were discussed. Furthermore, through SDS-PAGE analysis, the cold shock treatment was found able to delay the discomposition of proteins, hence to raise the tolerance of CI of Nai-plum fruit.
