摘　　要：[Objectives]The paper was to explore the optimum storage temperature of Amorphophallus cormifer microbulbs.[Methods]With A.cormifer as the raw material,the effects of different storage temperatures(4,12 and 20℃)on postharvest physiology of A.cormifer during the storage period of 80 d were investigated.[Results]There was no significant difference in starch content among the treatments,and the content of reducing sugar at 4℃was significantly higher than those of other treatments during the storage period.There was no significant difference in total water content among treatments,and the specific gravity of free water at 4℃was significantly lower than those at 12 and 20℃,respectively.At 60 d post storage,the POD activity at 4℃was significantly higher than those at 12 and 20℃,respectively.At the 80th day of storage,the PPO activity at 4℃was significantly lower than those at 12 and 20℃,respectively.[Conclusions]The low temperature of 4℃is more conducive to the storage of A.cormifer microbulbs,and the results also provide the theoretical basis for long-term storage of A.cormifer bulbs.
