To study the effect of different concentrations of 8-hydroxyquinoline citrate and sucrose on vase life and some qualitative and quantitative attributes of oriental lily cut flowers, a study was conducted using a factorial design with either continuous application of 8-hydroxyquinoline citrate (0, 100 & 200 ppm), sucrose (0, 2 & 4 %) in vases or spray application of a mixed solution of GA3 and BA (1:1) at two concentrations (0 & 50 ppm). Vase were placed in chambers at 25°C, relative humidity about 70% with a 14 h photoperiod maintained using fluorescent lamps (light intensity of 15 mmol m2 s1) at the top of the corolla.Data were recorded for some qualitative and quantitative attributes including vase life, fresh weight, solution uptake, changes of chlorophyll concentration in leaves.8-hydroxyquinoline citrate at 200 ppm concentrations along with 4% sucrose and 50 ppm mixed of solution GA3 and BA were the most effective in increasing vase life and maintaining keeping quality of cut lily flowers increased from 12.3 days in (control to22 days in the best treatment.
