The Effect of Dry and Wet Storage of Cut Lily (Longiflorum × Asiatic hybrids cv. CebDazzle) Flowers under Passive MAP Conditions

Lily is one of the most popular cut flowers that proper storage could ensure high quality of flowers during the supply chain. In this study the effect of 12 h pulse treatment of sucrose (3%) with or without 8-hydroxyquinoline citrate (8-HQC) under dry and wet modified athmosphrere packaging were evaluated on the cut lily (Lilium longiflorum Thunb. cv. CebDazzle) flowers. Flowers were kept at 8˚C for 15 days. To vase life predict at the end of supply chain, flowers were transferred from storage to the room temperature and the pack was opened. Followed flowers vase life, weight loss, charbohydrate, chlorophyll, pigment and some senescence related enzymes conent were measured every 5 days interval. The results showed that 8-HQC in combination with 3% sucrose extended cut flowers vase life. Otherwaise MAP under wet condtion in campare with dry condition had significant effect on the longevity and quality parameters of cut liles.The best water balance were obsereved on 8-HQC treating contain 3% sucrose under wet MAP condition. Moreover, the degradation of chlorophyll, carotenoids, phenol and anthocyanin as well as carbohydrate of the cut flowers was retarded during postharvest life. Protein degradation and antioxidant activities were controlled by the use of wet MAP in combination with8-HQC plus sucrose. It seems that this treatment could be able to provide primary carbohydrate levels for flowers to contiue their developmental stage, therefor, wet MAP condition during long transport and storage is preferred by cut lilies.
