Abstract: An experiment was conducted to study the Impact of plant growth regulators on growth and flowering of gladiolus cv. Candyman during 2015-16 at Department of Floriculture and Landscape Architecture, IGKV, Raipur. Three growth regulators with three concentration viz., NAA (25 ppm, 50 ppm and 100 ppm) GA₃ (200 ppm, 250 ppm and 300 ppm) CCC (150 ppm, 200 ppm and 250 ppm) each at three concentrations in addition to distilled water spray as control comprised ten treatments of this experiment. The experiment was laid out in a Randomized Block Design (RBD) with three replication. All the growth and flowering parameters were periodically observed. The results revealed that the treatment of GA₃ 200 ppm (T₄) attributed to superior results regarding the plant height, number of leaves, length of leaves, length of spike, length of rachis, number of floret per spike, diameter of florets, and vase life over all other treatments.
