This experiment was conducted to evaluated the effect of choline salt of maleichydrazide (C-MH) application on growth and root yield components of Bupleurum falcatum L. Flowering was delayed by C-MH application $17{\sim}35$ days. Twice application was more effective to delay flowering. Application of C-MH 2,000ppm at 30cm to 40cm of plant height reduced plant height 15cm, but increaced highly branches and the growth of root. The dried root yield per 10a was 27% higher in twice application of C-MH 2,000ppm than control plot.
