With the delay of harvest stage, the carbohydrate content of flower petals and the diameter of flower buds increased, but the vase life was shortened. Effects of abscisic acid (ABA) and sucrose on preservation of cut lilies were related to the harvest stage. Due to the lower level of soluble sugars and other energy source in early harvested cut lilies, the sucrose pretreatment turned to be particularly effective for extending the vase life and increasing the flower fresh weight and bud diameter. For the cut flowers harvested at middle stage, pretreatment with sucrose or ABA separately enhanced the preservation effect, which was not observed when pretreated with the combination of sucrose and ABA. The preservation effect of the harvested flowers at the late development stage was increased by the ABA pretreatments including ABA alone or ABA and sucrose (ABA+Suc). ABA improved sucrose uptake from the pretreatment solution and increased soluble sugar contents in cut flower petals. Combined with sucrose pretreatment, addition of ABA alleviated leaf chlorosis symptom of cut flowers harvested in early period.
