The research work entitled “Effect of pre-soaking of corms into plant growth regulators on growth and flowering of Gladiolus (Gladiolus grandiflorus L.) cv. American Beauty” was conducted at the Main Experiment Station, Horticulture, N.D. University of Agriculture and Technology, Kumarganj, Faizabad (U.P.) during the years 2013-14 and 2014-15. The corms were pre-soaked in different plant growth regulators as IAA (100, 200 ppm), GA3 (100, 200 ppm), NAA (100, 200 ppm), BA (100, 200 ppm), Ethrel (100, 200 ppm), ALAR (100, 200 ppm) and Maleic hydrazide (100, 200 ppm) for 12hrs as fifteen treatments which were replicated three times by Randomized Block Design (RBD). The observations were recorded at regular intervals for growth and flowering characters of gladiolus. The different characters like days taken in germination, plant height, number of leaves, leaf width, diameter of corms, number of florets/spike, spike length, spike weight, days taken for spike initiation and days taken for first floret to open were significantly improved by the use of GA3 @ 200ppm over all other treatments while the treatment comprised MH 200 ppm was showed lowest result for all chracters during both (2013-14 and 2014-15) the years of experimentation.
