摘      要：The effect on the germination and seedling growth of radish(Raphanus sativus)seeds were examined employing a dielectric barrier discharge(DBD)at atmospheric pressure and room temperature for various treatment *** plasma using argon gas of flow rate 21 m^(-1)was employed in this *** seeds were treated with DBD plasma for 1-5 min,*** characteristics,seedling growth parameters,the contact angle of the seed coat,water uptake capacity,mass loss,the temperature of the seeds,chlorophyll,and carotenoid contents of the seedlings were measured before and after the DBD plasma *** treatment of radish seeds significantly increased germination-related characters,including germination percentage,fresh and dry weight,vigor index,and total carotenoids ***,the cumulative production rate was found to be *** from the experiment indicate an acceleration in the water uptake of the radish seeds and make the seed surface hydrophilic by plasma *** electron microscopy analysis showed that etching effects on the seed coat occurred after the argon plasma treatments,which affected the wettability of the radish *** experimental findings showed that seeds being treated by DBD plasma for 2 and 3 min had a positive effect on the germination and seedling growth of radish.
