Abstract: An investigation on “Effect of plant growth regulators on vegetative and flowering parameters of gladiolus cv. Adigo Yellow†was carried out at Department of Floriculture and Landscape Architecture, College of Horticulture, Bengaluru (Under University of Horticultural Sciences, Bagalkot), during 2017-18. The experiment was conducted by planting the corms which were soaked in different plant growth regulators at different concentrations for 24 hours. The treatment comprised of BAP (25, 50 and 75 ppm), GA3 (50,100 and 150 ppm) and NAA (50,100 and 150 ppm) with control as check. The results revealed that, GA3 at 150 ppm recorded the early sprouting (9.00) and late sprouting was recorded in control (13.00), maximum sprouting percentage (83.91%) and NAA at 50 ppm was recorded minimum sprouting (66.03), maximum plant height (77.80), stem girth (2.19), spike length (68.10), rachis length (53.97), number of florets per spike (15.07), size of floret (10.80), weight of spike (82.69), vase life (14.03) were recorded in GA3 at 150 ppm and minimum values were recorded in BAP at 25 ppm. More number of leaves and maximum leaf area were recorded in BAP at 75 ppm. Whereas, minimum number of leaves and leaf area were recorded in control. These results emphasizes the significant differences among the different growth regulators with respect to vegetative and flowering parameters in gladiolus cv. Adigo Yellow, which impact on flower yield and quality.
