The present investigation was regulate to evaluate the flowering parameters of chrysanthemum cv. Dolly White in response to different concentrations of paclobutrazol and daminozide at Floriculture and Landscaping Block, College of Horticulture, VCSG Uttarakhand University of Horticulture and Forestry, Bharsar, PauriGarwal from June to December, 2019. The experiment was located on Randomized Complete Block Design with nine treatments. The treatments used were control, paclobutazol @ (30, 60, 90 and 120 ppm) and daminozide @ (250, 500, 750 and 500 ppm). Each treatment was replicated thrice. The cuttings were planted in 15 cm × 15 cm (length and diameter) size pots. Paclobutrazol and daminozide were applied at 30 and 60 days after planting of cuttings. The results of experiment acknowledge that all the applied concentrations of daminozide significantly improve number of days taken to bud appearance and bud showing colour and their results were found statistically at par with each other. However, minimum days taken to full bloom (118.37 ± 0.36 days) were observed from the plants sprayed with daminozide @ 1000 ppm and found statistically at par with daminozide @ 750 ppm (119.17 ± 0.57 days). The maximum flower diameter (3.54 ± 0.05 cm) was recorded in plants sprayed with daminozide 500 ppm and found statistically at par with daminozide 750 ppm (3.41 ± 0.03 cm). Maaximum number of flowers and flower longevity (20.29 ± 0.35 and 16.78 ± 0.58 days, respectively) were recorded from the plants drenched with paclobutrazol @ 90 ppm. Thus, it can be revealed that highest number of flowers and flower longevity, drenching of paclbutrazol @ 90 ppm was found best. However, for getting earliness in flower bloom spray of daminozide @ 750 ppm was found useful and flower diameter was found maximum from plants sprayed with daminozide @ 500 ppm
