Experiment was conducted by using following chemicals sucrose, AgNO3, IBA, sucrose+ IBA in different concentrations. Experiment was performed by 4 treatments each with 3 replications by CRD. In this experiment two preservatives sucrose and AgNO3 were used denoted as T2, T3, T4, T5, T6 in 2% sucrose.4% sucrose ,6 % sucrose and 50 ppm AgNO3, 100 ppm AgNO3 and 150 ppm AgNO3 respectively. IBA was used as a growth regulator in 25 ppm.50 ppm and 75 ppm concentrations. Tab water was used for control treatments. The results were very significant for treatments T3, T6 and T7 in most of observations. BecauseAgNO3 and sucrose were used in these treatments as preservatives .Vase life of the Gladiolus spikes was maximum in the treatment T6 and T3.Days of 50 % floret opened was also maximum in treatments T3and T6, hence prolonging the vase life by delaying the growth rate. The trend of water up take gg-1 was maximum in treatment T7. T8, T9, because in these treatments IBA was used as a growth regulator, so higher the growth rate higher was the rate of water up take ,thus delaying the vase life of the Gladiolus spikes. The other treatments also gave results superior to that of control (pure water). In general, treatments with sucrose and AgNO3 hastened flower opening, but the longevity of the spikes was increased compared to control and resulted in increased vase life.
