Abstract: The sucrose (S), 8 - hydroxyquinoline (8-HQ) and citric acid (CA) were used as the basic formula of fresh-keeping solution, then with four different inorganic salts CaCl2, NaCl, Al2 (SO4)3, CaCl2 and KAl(SO4)2 individually to study the fresh-keeping technology of rose cutting flowers. The vase life span, flower diameter, water trimmed value, soluble protein and reducing sugar content were analyzed and discussed. The results showed that all the fresh-keeping solution could extend the vase life span of rose cutting flowers, increased the flower diameter and improved water metabolism, decreased the decomposition velocity of protein and sugar. Among them, the fresh-keeping solution 2% S +280 mg/L CA +200 mg/L 8-HQ +1% CaCl2 was the best.

摘要： 以蔗糖(S)、8-羟基喹啉(8-HQ)、柠檬酸(CA)为保鲜液的基本配方，分别加入CaCl2 、NaCl、Al2(SO4)3、CaCl2+KAl(SO4)2 组成四种保鲜液，进行玫瑰切花保鲜实验。对切花瓶插寿命、花径、水分平衡值、可溶性蛋白含量和还原糖含量进行分析。结果表明，各种配方保鲜液均能延长玫瑰切花的瓶插寿命、增大花径、改善切花水分代谢状况、降低切花蛋白质和还原糖的分解速度。其中，保鲜液2% S + 280 mg/L CA + 200 mg/L 8-HQ + 1% CaCl2的保鲜效果最好。
