An experiment was conducted at the Department of Horticulture, Institute of Agriculture and Animal Science Paklihawa, Rupandehi to study the effect of different chemicals and essential oils on the vase life of cut flowers of gladiolus (Gladiolus grandiflora cv. “American Beauty”). The experiment was based on a completely randomized design with eight treatments (sucrose 4%, sucrose 4% + ethanol 25 + salicylic acid (200 ppm), sucrose 4% + silver nitrate (200 ppm), sucrose 4% + citric acid (200 ppm), sucrose 4% + ethanol 25%, sucrose 4% + ethanol 25% + eucalyptus oil 1%, sucrose 4% + ethanol 25% + palmarosa oil 1% and distilled water) for each treatment unit. Silver nitrate (200 ppm) had a maximum beneficial effect on fresh weight retention, solution uptake, spike diameter, and floret wilting at the end of vase life which was closely followed by Citric acid (200 ppm). The citric acid (200 ppm) had maximum positive effects on bud opening and floret opening at the end of vase life which was closely followed by Silver nitrate (200 ppm). And, the effects of silver nitrate (200 ppm) and citric acid (200 ppm) were the same on the basal floret diameter on the ninth day. A strong positive correlation existed between the vase life of cut flowers and other parameters such as fresh spike weight, solution uptake, bud opening, floret opening, and basal floret diameter. The longest vase life (18.56 days) was observed in silver nitrate (200 ppm), which was closely followed by citric acid (200 ppm) i.e., 18.11 days, and the shortest vase life (9.89 days) was observed in eucalyptus oil 1% in comparison to control (15.56 days). A blend solution of citric acid (200 ppm) and sucrose 4% is recommended to use for prolonging the vase life of gladiolus cut flowers.
