Abstract: [Objective] The paper was to explore the optimum storage temperature of Amorphophallus cormifer microbulbs. [Method] 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. [Result] 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. [Conclusion] 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.
