Abstract
Gladiolus is a flower of glamour and perfection which is known as the queen of bulbous flowers. The study was carried on cultivar ‘White Prosperity’. An investigation to find out the optimum doses of GA3, NAA and BA on gladiolus, the best combination of these plant growth regulators for better quality flower and higher yield and the effect of plant growth regulators on the morphological characters of gladiolus was carried out at the Horticulture Research Center, College of Agriculture, Sardar Vallabhbhai Patel University of Agriculture & Technology, Meerut (U.P.), during the year 2018-19. Three growth regulators viz., GA3, NAA, and BA at three levels of concentration with three methods of application viz., corm dipping, foliar spray and corm dipping + foliar spray in addition to control comprised 28 treatments of this experiment. The experiment was laid out in a randomized block design (RBD) with three replications. Application of GA3 at 400 ppm or 800 ppm concentration was significantly superior to other treatments in improving the growth, days of corm 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, weight of corm per plant. NAA at 200, 400 and 600 ppm increase the number of leaves per plant, plant height, and weight of cormels per plant. BA at 100 ppm increased diameter of corms, number of cormels per plant, number of corms per plant and yield of corms and cormels. When the different treatments of application were compared, it was found that corm dipping + foliar spraying treatment was significantly superior to other treatments.
