EFFECT OF SOME CHEMICAL TREATMENTS ON QUALITY AND VASE LIFE OF LISIANTUS (EUSTOMA GRANDIFLORA) CUT FLOWERS
Two cultivars of lisianthus cut flowers (Eustoma grandiflora Mariachii. cv. Blue & Eustoma grandiflora Maraichii. cv. Cream) were used to test chemical treatments on flower vase life. Cut flowers of lisianthus were kept in pots containing chemical solutions of aluminum sulfate (100, 150 or 200 ppm), 8-hydroxyquinoline citrate (200, 300 or 400 ppm), ethanol (2, 4 or 6%), cobalt chloride (200, 300 or 400 ppm), copper sulfate (100, 150 or 200 ppm), a combination of 150 ppm citric acid and 150 ppm aluminum sulfate, with water as control. In all treatments, except control, 2.5% sucrose was used and all flowers were maintained at 25°C. Qualitative and quantitative attributes were measured and analyzed including vase life, fresh weight, ethylene production rate, solution uptake. The two cultivars reacted differently to the chemicals utilized in the experiment. Copper sulfate at 100 ppm along with 2.5% sucrose was the most effective in extending vase life of the blue cultivar while 8-hydroxyquinoline citrate at 300 ppm concentrations, along with 2.5% sucrose, was the most effective for extending vase life and maintaining quality for the cream cultivar of lisianthus.
