Abstract: In order to extend the vase life and improve the preservation quality of gerbera cut flowers, 16 kinds of preservatives’ effects on the flower diameter change of gerbera fresh cut flowers, vase life and bottle insertion viewing values were studied with ‘Travisa’ gerbera variety as an example by adding 0,0.2,0.4,0.6 mL detergent in 100 mL preservative solution and 0,15,30,45 mL of fresh orange juice cross combination, and adding 1% NaCl and 3% white sugar mixed solution. The results showed that the treatment with the juice content of 300 ml/L could delay the opening of the cut flower, and the fresh-keeping effect was better. Under the condition of the same juice content, the fresh-keeping effect of edetergent of 0.4 mL/L was better than that of 0,2 and 6 mL/L. Treatment with 300 mL/L of juice+4 mL/L detergent+1% salt solution+3% sugar solution was the most beneficial to improve the fresh-keeping effect of fresh cut flowers, and was an ideal home-made preservative.
