摘要: 以亚洲杂种系百合‘Prato’为试材, 在基本保鲜剂成分( 20 g·L-1蔗糖、250 mg·L-1
8 - 羟基喹啉、1 g·L-1 CaCl2 ) 的基础上加水杨酸进行瓶插处理, 研究其保鲜效应。结果表明, 用含水杨
酸的保鲜液能延长瓶插寿命、单花寿命, 增加花枝鲜样质量和花瓣中可溶性蛋白质的含量, 推迟呼吸和乙
烯峰的到来并降低峰值, 减少花瓣中丙二醛和游离脯氨酸的积累。两种保鲜剂处理对百合切花叶片都有较
好的保绿效果。

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.
