Qingshu 9 potato tubers were used as raw materials to investigate the impact of different storage temperature(4,10,15 and 20 ℃) on quality and postharvest physiology of potato tubers during storage of 150 days.The result showed that,during the storage,starch content declined,while reducing sugar content,weight loss,sprout rate,decay rate,conductivity and MDA content increased,the activity of POD and PPO showed a trend of rise first and then fall.Different storage temperature have different effects on potato storage quality and postharvest physiology.The fastest changes of quality and postharvest physiology were observed from potato stored at 20 ℃,and followed by 15 ℃ and 10 ℃,4 ℃ was the most suitable temperature for storing potato tuber,it is helpful to maintain storage quality and delay senescence of potato tubers.
