摘　　要：[目的]筛选适宜切花腊梅保鲜的药剂及其浓度。[方法]以素心腊梅为试材，以青霉素（700、900、1100mg／L）、硝酸银（102、136、170mg／L）8-羟基喹啉（50、70、90、200mg／L）3种药剂不同浓度进行正交试验，筛选适于切花腊梅保鲜剂配方，测定切花腊梅的花枝鲜重、水分平衡值、开花率、糖及蛋白质含量5个指标。[结果]根据素心腊梅的折线图和花枝鲜重、糖含量、蛋白质含量、水分平衡值、开花率5组数据分析，在正交试验的9个处理中，以凡B2c，（青霉素900mg／L＋硝酸银136mg／L＋8-羟基喹咛90mg／L）对延缓切花腊梅的衰老有明显的效果，在冬季条件下素心腊梅保鲜可达15d，同时比对照延长观赏寿命6—7d。[结论]较高浓度的青霉素、硝酸银和8-羟基喹咛的药剂组合对切花腊梅具有明显的保鲜效果。[ Objective ] This study aimed to screen the medicaments suitable for fresh-keeping of cutting-flower of Chimonanthus praecox and their eonen. [ Method] With C. praecox var concolor as the tested material, 3 kinds of medicaments as Penicillin （700,900, 1 100 mg/L）, AgNO3 （ 102, 136, 170 mg/L） and 8-HQ （50, 70, 90,200 mg/L） were used to make the orthogonal test, the fresh-keeping formula that was suitable for cutting-flower of C. praecox was screened and 5 indexes of fresh weight of flower shoots, water balance, blooming rate, soluble sugar content and protein content of C. praecox were determined. [ Result] Based on the line graph of C. praecox vat concolor and the data a- nalysis on 5 groups of fresh weight of flower shoots, water balance, blooming rate, soluble sugar content and protein content, among 9 formula treatments in the orthogonal test, the formula of A2B2C3 （900 mg/L penicillin ＋ 136 mg/L AgNO3 ＋90 mg/L 8-HQ） had obvious effect of postponing the senescence of cutting-flower of C. praecox, which could keep the freshness of C. praecox var concolor for 15 d in winter and prolong the ornamental life by 6 - 7 d compared with CK. [ Conclusion ] The medicament eombimation of penicillin, AgNO3 and 8-HQ with higher conen, had obvious fresh-keeping effect on C. praecox.
