Abstract:
The present investigation was conducted to evaluate the vegetative 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, Pauri Garwal from June to December, 2019. The experiment was laid out 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 pots of size 15 cm × 15 cm (length and diameter). Paclobutrazol and daminozide were applied at 30 and 60 days after planting of cuttings.
The results of investigation revealed that shortest plant height (18.22 ± 0.35 cm) was recorded from the plant drenched with paclobutrazol @ 120 ppm and found statistically at par with paclobutrazol @ 60 and 90 ppm (19.82 ± 0.64 cm and 18.69 ± 0.57 cm, respectively). The diameter of main stem and plant spread (5.02 ± 0.05 mm and 21.33 ± 0.24 cm, respectively) were recorded maximum in plants sprayed with daminozide @ 1000 ppm and found statistically at par with paclobutrazol @ 90 ppm (4.93 ± 0.01 mm and 20.32 ± 0.38 cm, respectively).
Thus, it can be concluded that drenching of paclobutrazol @ 60 ppm was found effective in getting dwarf plant. For improving maximum plant spread paclbutrazol @ 90 ppm was found best.
