The preliminary result of an atmospheric non-thermal plasma jet gemination enhancement of radish seeds was presented.the plasma reactor was a simple design;connect a small acrylic box at the tip of the plasma jet model.from the experimental results,it could be confirmed that plasma treatment has a positive effect on improving the growth rate of radish seeds. At the experimental condition of 140 watts of power generation,the growth rate of plasma treated seeds were9-12 percent of the dry radish weight,approximately higher than that of the un-treated seeds. The average root lengths of plasma treatmant cases were also longer that of the controlled case by 3 centimeters,approximately.
