Abstract: Several cut flowers such as Gladiolus hybridus and so on were treated with the methods of preserving fresh, and the changes of its endogenous phytohormones were determined. The results showed that the effect of preserving fresh by using the method of inhibit ethylene production was not ideal. Otherwise, the senescence of medium-lived flowers such as Gladiolus hybridus, Rosa sertata, Rosa chinensis ect. and short-lived ones such as Epiphyllum oxypetalum, Nopalxochia ackerrnannii could be postponed by promoting the release of endogenous ethylene: delaying senescence of short-lived and medium-lived flowers such as Althaea rosea and Hemerocallis minor could be controlled by promoting water absorbtion. The results proved once again that the ability of endogenous ethylene production and the ratio of CTK/ABA was much higher in the long-lived flowers than in the short-lived ones.
