Abstract: Gerbera is the one of the important cut flower in the international flower market. In this experiment ‘Szogun’ and ‘Marzena’ varieties were treated with growth retardants, CCC (250ppm, 500ppm and 750ppm) and MH (750ppm, 1000ppm and 1250ppm). An experiment entitled Response of Gerbera (Gerbera jamesonii Bolus) to growth retardants for growth, flower yield and quality under naturally ventilated poly house condition was conducted at Horticulture Research Field, Department of Horticulture, during the year 2018-2019. The experiment was laid out in Factorial Randomized Block Design having 14 treatments T1 (Control + Szogun),T2(MH@250ppm + Szogun), T3 (MH@500ppm + Szogun), T4(MH@ 750ppm + Szogun), T5(CCC@750ppm + Szogun), T6(CCC@1000ppm + Szogun), T7(CCC@1250ppm + Szogun),T8 (Control + Marzena),T9(MH@250ppm + Marzena), T10(MH@500ppm + Marzena), T11(MH@ 750ppm + Marzena), T12(CCC@750ppm + Marzena), T13(CCC@1000ppm + Marzena), T14(CCC@1250ppm + Marzena) with three replications. The result revealed that treatment T1 (Control + Szogun) was best in terms of maximum plant height (23.79 cm), plant spread (32.35 cm), number of leaves (15.33). The treatment T14 (CCC @ 1250ppm + Marzena) was found superior in most of the flower qualities like number of flower per plant (11), days of first flower bud emergence (76.08 days), flower diameter (12.06 cm), stalk girth (1.88 cm), stalk length (46.43 cm) and vase life of the flower (9.13 days).
