Abstract
This study was conducted to development of rapid propagation method by leaf cuttings in Hibiscus hamabo native to southern seaside of Korea, and special object of this study was to determine the effects of IAA, IBA, and NAA on rooting in leaf cuttings of H. hamabo. Rooting was promoted by dipping treated with IAA and IBA. And rooting percentage was greatest at 1,000 and 2,000$mg{\cdot}L^{-1}$ IBA. At higher concentrations of IAA and IBA, more adventitious roots were developed. Also, IAA at high concentrations (above 2,000$mg{\cdot}L^{-1}$) and IBA ranged from 500~2,000$mg{\cdot}L^{-1}$ promoted on root number and rootingratio. However, root formation in Hibiscus leaf cuttings inhibited by NAA application.
