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.
