Among all the pulsing treatments i. e.T1.-control (with distilled water), T2-Sucrose 5%, T2-Sucrose 5%+AgNO3 (100 mg/1), T4-Sucrose 5%+AgNO3, (200 mg/1). T5-Sucrose 5%+Al, (SO4)3.16H2O (100 mg/1), T6-Sucrose 5%+Al2 (SO,),. 16H,0 (200 mg/1), T7-Sucrose 5%+Citric acid (1 00 mg/1) and T8-Sucrose 5%+Citric acid (200 mg/1), treating of cut spikes with sucrose 5%+Al2 (SO4)3 16H2O (200 mg/1) was found to be the most effective in extending vase life upto 9.50 days, maximum number of florets opening at a time (7.67), solution absorption by cut spikes (64.98 ml) and minimum number of days taken for basal floret opening (2.08 days) as compared to other treatments.
