The document discusses experiments on treating cut tuberose and rose flowers with various chemicals and preservatives to improve vase life and quality. Chemicals like silver nitrate, calcium chloride, and a fungicide containing copper and mancozeb delayed flower opening and extended vase life of tuberose flowers compared to ascorbic acid treatments or no treatment. Calcium chloride was also effective in delaying petal senescence and flower wilting. Experiments on rose flowers found that treatments with salicylic acid and glutamine at different concentrations affected quality parameters and longevity, with some treatments maintaining vase life longer than others.
