Relative Effects of Different Preservatives on the Cut Flowers

In this experiment,sucrose,8-hydroxyquinoline sulfate,citric acid,sodium dihydrogen phosphate,and so on was prepared in different formulations preservatives on four kinds of fresh cut flowers(carnation,gerbera,chrysanthemum,rose) in vase experiment,observed the influence of vase life and cut quality in the local natural conditions,to select a better formula.The results showed that,Handling 1-3(5% sucrose+200 mg/L 8-hydroxyquinoline sulphate+50 mg/L acetic acid silver) on cut carnation good effect;treatment 2-2(3% sucrose +150 mg/L citric acid+200 mg/L 8-Hydroxyquinoline sulfate) on the inhibitory effect of Chrysanthemum Cut elbow was good,could effectively extend the flowering period;treatment 3-1(3% sucrose+30 mg/L silver nitrate +150 mg/L citric acid) on the preservation of cut chrysanthemum was better;treatment 4-1(2% sucrose+200 mg/L 8-hydroxy quinoline sulfate+200 mg/L calcium nitrate) and 4-2(4% sucrose+50 mg/L 8-hydroxyquinoline sulfate+100 mg/L erythorbate) on cut rose flowers all had a better quality of products.
