Effect of different pulsing treatments on physiological behaviour and quality of cut daffodil was studied. Uniform scapes of daffodil at goose-neck stage were pulsed in 11 different pulsing solutions for 2, 3 and 6 hours duration. Pulsing treatments comprised of sucrose 6% alone and in combination with different levels of aluminium sulphate (25, 50 and 75 mg L−1), sodium benzoate (30, 60 and 90 mg L−1) and ascorbic acid (20, 40 and 60 mg L−1). Distilled water without any chemical served as control. After pulsing scapes were transferred into other vases containing distilled water for assessment of their various post harvest attributes. Results indicate that pulsing of daffodil scapes in sucrose (6%) helped in improving the flower turgidity, membrane integrity and vase life as compared to control. Increased pulsing duration positively improve these parameters. Addition of different biocides further improves these parameters with best results in aluminium sulphate, followed by ascorbic acid and sodium benzoate.
