This experiment was conducted to obtain the basic information for the increase of germination percent by the treatment of stratification, soaking and Gibberellin(GAa) in Angelica gigas Seeds caltivated in 1989. The germination percent was increased by 30% with stratification, and the effect of low temperature did not differ significantly. The optimum soaking temperature and periods were found to be 4days at 20℃ and 6days 10℃ of water temperature. When exchanged water every day during soaking period, inhibitors were more extracted than non-exchange one. The exogenous application of GA₃ also increased germination percent about 20% campared with control, and the reasonable level was 2ppm in soaked seed and 5ppm in non-soaked seed.
