Abstract: In this experiment, freshly harvested Asiatic hybrid lilies were treated with fundamental pre
servative ingredients ( 20 g·L-1 Sucrose, 250 mg·L-1 8-HQ, 1 g·L-1 CaCl2 ) plus 35 mg·L-1 salicylic
acid, and then the p reservation effectswere investigated. The results indicated that the p reservative containing
salicylic acid p rolonged vase life and the longevity of individual flowerlets, increased the fresh mass and solu
ble protein content, lowered the respiration rate and ethylene evolution, delayed the occurrence of resp iration
and ethylene peaks, retarded the chlorophyll degradation in the leaf. It also decreased malondialdehyde
(MDA) and free proline accumulation in the petal. Both the basic p reservative and the basic preservative plus
salicylic acid were effective in preventing leaf yellowing.
