An investigation was undertaken to analyze the effect of plant growth regulators on growth and flower quality of gladiolus cv.'H.B.Pitt’.In the present study it was found that the maximum height of the plant (59.43cm), number of leaves (13.9), leaf area (64.8cm2) were recorded by treatment GA3 200ppm foliar spray. Lowest plant height was observed in treatment CCC 750 ppm spray. Minimum number of leaves/ plant (10.8) and leaf area (64.8cm2) were recorded in CCC 250 ppm / plant as foliar spray. In flower quality parameters, maximum number of florets/ spike (13.4), floret length (8.4.cm), length of spike (80.28 cm) and length of rachis (41.50 cm) were recorded with foliar spray of GA3 200 ppm.
