Abstract:
The experiment entitled “Effect of different vase solutions on vase life of gladiolus (Gladiolus grandiflorus) cv white prosperity” in the Department of Horticulture, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj, during the month of December, 2021. The experiment was conducted in Complete Randomised Design replicated thrice with eleven treatments. (T₀)Distilled water (control), (T₁)-2% sucrose, (T₂)- citric acid @ 300ppm + 2% sucrose, (T₃)- salicylic acid @ 50ppm+ 2% sucrose, (T₄)- salicylic acid @100ppm+ 2% sucrose, (T₅)- salicylic acid @ 150ppm+ 2% sucrose, (T₆)- STS @ 150ppm+ 2% sucrose, (T₇)- STS @ 200ppm+ 2% sucrose, (T₈)- STS @ 250ppm+ 2% sucrose, (T₉)- AgNO₃ @ 50ppm+ 2% sucrose, (T₁₀)- AgNO₃ @ 100ppm+ 2% sucrose, (T₁₁) - AgNO₃@ 150ppm+ 2% sucrose. The total number of florets opened during the vase life of gladiolus spike (10.3) in (T₈)- STS @250ppm+ 2% sucrose, floret opening percentage (93.2) in (T₈)- STS @ 250ppm+ 2% sucrose, floret diameters 1^st (9.4cm), 3^rd (8.9cm), 5^th (8.2cm), solution uptake (128ml), (109.3ml), (48.3ml) in(T₈)- STS @ 250ppm+ 2% sucrose, prolonged vase life (11.7) days and maximum time taken for the deterioration of the 1^st floret in white prosperity variety of gladiolus is (6.2) days in (T₈)- STS @ 250ppm+ 2% sucrose. Thus the best vase solution to prolong the vase life of gladiolus is found to be sodium thio sulphate @ 250 ppm because it inhibit the microbial proliferation in the solution and sodium thiosulfate also reduced the oxidative activity, hence the microorganism cannot survive in the solution which gave the best result.
