Abstract

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.

Key words: Prunussalicina Lindl.Var.cordata, phytohormones, cold shock treatment, chilling injury, protein, storage
