摘　　要：以金鱼草切花为试材,以羟基喹啉、柠檬酸、盐、蔗糖、磷酸二氢钠混合液、硝酸银为保鲜剂,研究了不同保鲜剂配方对金鱼草鲜切花瓶插寿命、花径、鲜重、吸水量、蒸腾量等外观品质和花色素苷含量、细胞膜透性、可溶性糖含量、可溶性蛋白含量、维生素C含量等内含物质的影响,以期为切花保鲜提供参考。结果表明:在瓶插保鲜试验中,以200mg/L 8-羟基喹啉柠檬酸盐+3%蔗糖+150mg/L柠檬酸+75mg/L磷酸二氢钠混合液的保鲜效果最好;与对照相比,该保鲜液可延长切花寿命9d;达盛开期晚4d;到瓶插的第21天,切花鲜重比对照增加26g、水分平衡值高1.9g;在细胞膜透性变化方面,瓶插后期的第21天,导电率为83.6%,比对照少8.1%;其可溶性糖含量的最大值比对照高0.1g/100g样品;可溶性蛋白含量在第13天达到最大值,且后期以该处理的下降幅度较为缓慢;在瓶插后期的第21天,维生素C含量比对照高44.2839mg/100g样品。Taking Antirrhinum majus cut flower as material, using 8-hydroxyquinoline citrate,citric acid,salt,sucrose, solution of sodium dihydrogen phosphate, silver nitrate as preservatives, the effect of different preservatives on the exterior qualities （vase-life, flower diameter, fresh basis, water absorption, transpiration） and interior compositions （geniposide in anthocyanidin, cell membrane permeability, soluble sugar content, soluble protein content, content of vitamin C） of Antirrhinum majus were studied,in order to provide a reference for preservation of cut flower. The results showed that in the preservation experiment of Antirrhinum majus cut flower, the mixture of 8-hydroxyquinoline citrate （200 mg/L）＋ sucrose （3%）＋ citric acid （150 mg/L）＋ solution of sodium dihydrogen phosphate （75 mg/L） could produce the best preservation effect;compared with CK,the preservation could prolong the life of cut-flower 9 days more （approximately 60%）;4 days delayed to bloom stage;at the 21^th day of vase,fresh basis increased 26 g more;equilibrium value of moisture was 1.9 g higher. In the aspect of the change of cell membrane permeability,at the 21^th day of vase, conductivity was 83. 6%which was 8. 1% less,maximum value of soluble sugar content was 0. 1 g/100g （sample） higher and content of vitamin C was 44. 2839 mg/100g （.sample） higher when compared with CK.
