Abstract: Fresh daylily is a traditional characteristic vegetable in China, which has high nutritional and economic value, but it is extremely susceptible to a series of deterioration phenomena. This paper reviews recent studies on the biological changes associated with postharvest senescence in fresh daylily, the underlying physiological and biochemical metabolic mechanisms, the factors affecting postharvest senescence in fresh daylily, and postharvest preservation techniques. We believe that this review will provide a novel idea for understanding the senescence mechanism of fresh daylily and improving its postharvest preservation.

Key words: daylily; postharvest senescence; physiology and biochemistry; influence factors; storage and preservation
