Enhancing Vase Life of Rose Flower 'Cardinal' by the Use of Different Chemicals

A lab experiment was conducted to study the effect of different doses of certain preservative solutions, i.e. sucrose and chemicals, i.e. copper sulphate and kinetin on cut rose flower ('Kardinal'). There were 12 treatments replicated three times. Data  regarding  vase life, dry weight, solution uptake, and percentage of petal drop were collected  and analyzed statistically by using completely randomized design (CRD)  with  factorial arrangement of flowers  and  interpreted  according  to LSD  test. Cut rose flowers were obtained from commercial grower and treatment was done  with CuSO₄ at three concentrations of 200, 300, and 400 ppm, kinetin with 25, 50, and 75 mg/L, sucrose at 2%, 4%, and 6% w/v, and mix solutions of CuSO₄ and kinetin with three concentrations, CuSO₄ (200ppm) + kinetin (25 mg/L), CuSO₄ (300 ppm) + kinetin (50 mg/L) and CuSO^₄ (400 ppm) + kinetin (75 mg/L) and  tab water (control). After treatment the cut roses had been kept at room temperature (25 °C) under normal day light and natural ventilation. Results  indicated  that 6% sucrose  treatment  significantly  increased  vase  life  among all other treatments and  improved  postharvest  visual  quality  of  this  cultivar  by  retaining  leave freshness even at the end of vase life.
