The present investigation was carried out to study the effect of plant growth regulators on sprouting, vegetative characters, flowering and corm production in Gladiolussp. cv. Sancerre at the Experimental Farm of Horticulture Department, CCS HAU, Hisarduring 2014-2015. Corms were dipped overnight in the solution of BAP (25, 50 and 100 ppm), GA3 (200, 300 and 400ppm) and NAA (400, 500 and 600 ppm) including water dipping as control. The gladiolus corms in NAA treatment could not germinate. Minimum days taken for sprouting of corms (12.96 days), maximum sprouting percentage (95.83%), maximum number of florets per spike (14.41) and maximum length of spike (56.11 cm) was found in GA3 300 ppm treatment whereas maximum plant height (48.25 cm), number of spikes per plant (1.89), diameter of basal floret (9.93 cm), duration of flowering (16.21 days), weight of corm per plant (28.59 g) and diameter of corm (6.03 cm) was observed maximum in GA3 400 ppm. BAP significantly increased the number of corms per plant, whereas number (14.01) and weight of cormels per plant (4.09g) were recorded maximum in GA3 200 ppm.
