Abstract: The"qingzha"chestnut treated at 50℃for 60min was used for studying the storage effect and postharvest physilogical and bioch emical changes .It indicated that re spiration rate,POD activity and CAT activity were controlled by heat tre atment,while amylase activity,soluble sugar and reductive sugar conte nt were reduced.The growth and spread o f fungi were notably controlled during storage period and weight loss rate was also lower than the control CK.But VC content was reduced after heat treatment.

Key words: chestnut, heat treatment, storage e ffect, postharvest physiology and b iochemistry
