Effect of Chemical Preservatives on Vase Life of Cut Rose cv. Top Secret

An experiment was conducted in the laboratory of department of Horticulture, Ch. Charan Singh University Campus, Meerut (U.P.) India, during October 2020 under the title of effect of chemical preservatives on vase life of cut rose cv. Top Secret. The treatments involved in the study were nine in numbers viz. T₁ Control (distilled water), T₂ (Al₂SO₄ @ 100ppm + 1% sucrose), T₃ (Al₂SO₄ @ 200ppm + 2% sucrose), T₄ (Al₂SO₄ @ 100ppm + 4% glucose), T₅ (Al₂SO₄ @ 200ppm + 6% glucose), T₆ (AgNO₃ @ 50ppm + 1% sucrose), T₇ (AgNO₃ @ 100ppm + 2% sucrose), T₈ (AgNO₃ @ 50ppm + 4% glucose) and T₉ (AgNO₃ @ 100ppm + 6% glucose). Parameters studied in the experiment were fresh weight change (g), water uptake (ml/cut stem), flower diameter (cm) and vase life (days). Among all the preservatives, the maximum increase in fresh weight (+3.63 g) and maximum water uptake on 4^th day and at senescence day (18 ml and 40.33 ml respectively) were recorded under the AgNO₃ @50 ppm+1% sucrose while The maximum flower diameter (7.26 cm) and vase life (11.33 days) were recorded under the AgNO₃@100ppm + 6% glucose as compared to other treatments.
