The present investigation was carried out to study the effect of different growth regulators on propagation of China rose (Hibiscus rosa-sinensis) in subtropical zone of West Bengal under natural ventilated polyhouse at Jaguli farm of Bidhan Chandra Krishi Viswavidyalaya, Mohanpur, Nadia, West Bengal, during 2014-15 and 2015-16. All parameters were significantly varied among the treatments during investigation (T1:IAA @1000ppm, T2:IAA@2000ppm, T3:IAA @3000ppm, T4:IBA @1000ppm, T5:IBA @2000ppm, T6:IBA @3000ppm, T7:NAA @1000ppm, T8:NAA @2000ppm, T9:NAA @3000ppm, T10:Rootex, T11:Control ). After studying of two consecutive years, it has been found that NAA at all concentrations(1000-3000 ppm) may taken for rooting of China rose, but higher doses is more beneficial in this aspect during rainy season in subtropical zone, the second best growth regulator of IBA at 3000 ppm may also be considered. Semi hard wood cutting is better than tip cutting for propagation of China rose.
