Abstract
A field study on effect of 6-benzylaminopurine (BAP), Gibberellic acid (GA3) and Indole-3-butyric acid (IBA) @ 50, 100 & 200 ppm on vegetative growth and flower production in two varieties of gladiolus was carried out at College of Horticulture and Forestry, Jhalawar during 2015-16.It was found that cv. American Beauty with treatment of 200 ppm GA3 recorded the minimum number of days taken for sprouting (10.20 day), days to spike emergence (71.40), days to first floret opening from spike emergence (14.07) and maximum leaf length (44.13 cm), leaf width (3.19 cm),number of florets per spike (13.67) andfloret diameter (9.87 cm).The maximum plant height (105.53 cm), number of leaves per plant (9.33), spike length (88.13 cm), and rachis length (47.33 cm) were recorded at GA3 200 ppm in cv.Psittacinus Hybrid.
