The present study on the effect of plant growth regulators on growth, flowering and corm production of gladiolus was carried out during 2014-15 with 10 treatment combinations, comprising two cultivars (Arka Amar and Bindya) treated with two levels each of GA (75 ppm and 125 ppm), NAA (75 ppm and 125 ppm) and control (distilled water) replicated thrice in a Completely Randomized Design and analyzed under factorial setup to study the interactions at K.N.K. College of Horticulture, Mandsaur, RVS Krishi Vishwa Vidyalaya, Gwalior (M.P.). Treatment with GA 125 ppm recorded the earliest corm sprouting, maximum plant height, number of leaves per hill and length of the longest leaf, earliest spike emergence, minimum number of days taken for first floret to show colour, earliest opening of first floret, maximum length of spike, number of florets per spike as well as diameter of florets. The maximum number of corms and cormels per hill was recorded under GA 125 ppm. NAA 125 ppm recorded the maximum leaf width, maximum weight of corms, diameter of corms and weight of cormels per hill. Between the cultivars studied, Arka Amar was found to be superior in respect of all growth and flowering parameters except the leaf width and diameter of florets which recorded higher values in Bindya. Arka Amar was observed as best for number of corms, cormels and weight of cormels per hill, whereas Bindya recorded maximum weight and diameter of corms.
