An experiment was conducted to study the effect of benzyl adenine and gibberellic acid on flowering and flower quality attributes of gladiolus (Gladiolus hybridus L.) cv. summer sunshine in Department of Floriculture and Landscape Architecture, College of Horticulture, Mudigere (Under University of Agricultural and Horticultural Sciences, Shivamogga) during 2017-18. The experiment was consisted with sixteen different treatments viz., BA (100, 200 and 300 ppm), GA3 (150, 200 and 250 ppm) and their combinations along with the control. Each treatment was replicated thrice in Randomized Complete Block Design (RCBD). The results revealed that GA3 at 150 ppm recorded minimum days taken for spike initiation (66.27), first floret opening (73.73 days), 50 per cent flowering (77.87 days), maximum spike girth (12.37 mm), spike weight (98.03 g), floret length (10.73 cm) and floret diameter (10.33 cm). However, GA3 at 250 ppm recorded maximum duration of flowering (24.40 days), spike length (94.07 cm), rachis length (60.70 cm), florets per spike (18.80) and vase life (15.00 days). Whereas, BA at 300 ppm exhibited the maximum number of days for spike initiation (85.83), first floret opening (91.40 days), 50 per cent flowering (96.17 days) and maximum spike yield per plant (3.30).
