Considering of small size of seeds and long dormancy periods and low germination rates, experiments of coptis seeds soaked with GA_3 and KNO_3 and CaCl_2 were conducted at laboratory. Results indicated that coptis grown well and germination rates and vigor, 67.3% and 42.4%, of seeds soaked with GA_3 concentration of 1.44 mmol/l were relatively high. This concentration may be applied in coptis production. However, concentrations of KNO_3 and CaCl_2 still need to be studied further.
