| Abstract | The effect of atmospheric air dielectric barrier discharge plasma on seed germination and early growth has beeninvestigated in rice. Rice seeds were exposed to plasma for 10, 30 and 60 s. It is shown that plasma treatment had positiveeffects on germination of rice seeds. Seeds exposed to plasma for 60 s had the highest germination rate. Vigor index andgermination speed of treated seeds were higher in comparison to untreated seeds. Characteristics of seedling growth, includingshoot length, fresh weight and dry weight of shoot and roots were improved by plasma treatment. The contents of photosyntheticpigments tended to increase in the seedlings from treated seeds. In addition, the surface of rice seeds was modified by treatingwith plasma. These results suggest that the exposure of rice seeds to plasma has the potential to promote seed germination andseedling growth by changing the surfaces of rice seeds. |
