The present investigation entitled “Effect of plant growth regulators on growth and flowering characters of gladiolus (Gladiolus hybridus Hort.) cv. White Prosperity” was conducted at Horticulture Research Center (HRC), College of Agriculture, Sardar Vallabhbhai Patel University of Agriculture & Technology, Meerut-250110 (U.P.) during the rabi season of 2018-2019. The investigation revealed that plant growth regulators showed significant results on gladiolus as GA3 at 400 ppm or 800 ppm concentration was significantly superior to other treatments in improving the growth, days of sprouting, plant height, length of longest leaf, number of days required for visibility of first spike, days required for opening of first floret, diameter of spike, number of florets per spike, diameter of floret, longevity of spike. NAA at 200, 400 and 600 ppm increases the number of leaves per plant, plant height. When the different treatments of application were compared, it was found that corm dipping + foliar spraying treatment was significantly superior to control.
