Abstract: Taking Pleurotus eryngii as the material,the experiment was carried out. In the experiment,P. eryngii was stored in 2,4,6,8,10 and 12 ℃. The effects of different storage temperatures on postharvest physiology and quality of P. eryngii were studied under different storage temperatures. The results showed that P. eryngii stored at 2 and 4 ℃ preferably maintained the activities of superoxide dismutase(SOD)(p<0.01) and catalase(CAT)(p <0.05),inhibited effectively the rapid erosion of protein,VCand total sugar,and rapid increasing of malondialdehyde(MDA)(p<0.01),reduced effectively the activity of polyphenol oxidase(PPO)(p<0.05),and delayed quality deterioration and aging process. Thus,2 ~4 ℃ was suitable for storage of P. eryngii,which provide a theoretical basis for the storage and preservation.
