Effects of Different Vase Solutions on Fresh-keeping Effects of Fresh-cut Rose

[Objective]The paper was to explore the effects of different vase solutions on fresh-keeping effects of fresh-cut rose,and to provide reference for fresh-keeping activities of fresh-cut rose.[Method]Acid oxidiation-potential water(AOW,p H 2-3,redox potential ORP≥1100 mv effective chlorine concentration 50 mg/L),melatonin solution(MT,45 mg/L),sodium hypochlorite solution(NaClO,95 mg/L),acidic oxidiation-potential aqueous solution+melatonin solution(50 mg/L AOW+45 mg/L MT),acidic oxidiation-potential aqueous solution+sodium hypochlorite solution(50 mg/L AOW+95 mg/L NaClO)and melatonin solution+sodium hypochlorite solution(45 mg/L MT+95 mg/L NaClO)were used as vase solutions to explore their fresh-keeping effects on fresh-cut rose.[Result]Compared with the control group of distilled water,all the six kinds of vase solutions had fresh-keeping effects on fresh-cut rose.AOW showed obvious fresh-keeping effects on fresh-cut rose,and the vase life could be extended by 1-4 d.Melatonin,AOW+melatonin,melatonin+sodium hypochlorite had the second best preservation effects,which could prolong the vase life by 1-3 d.The fresh-keeping effects of sodium hypochlorite and AOW+sodium hypochlorite had no significant difference with that of the control group,and the vase life could be prolonged by 1-2 d.[Conclusion]The study provides a certain theoretical basis for the application of fresh-cut flower preservative on rose.
