Cold plasma therapy has a wide potential for seed germination. Sometimes even though moisture and temperature are in sufficient amounts seeds of many plant species fail to germinate. Thereby to increase the germination potential of such plant seeds need an exposure to stressed condition. However many times it happens that stressful conditions result in decreased growth. This limitation can be overcome by cold plasma therapy.For this treatment a non-thermal dielectric barrier discharge is used. This technique plays an important role in seed germination. However, the effect on germination rate by exposure to cold plasma varies for different species. Overall it has been observed that upon optimizing the plasma dosage an enhancement in seed germination along with increased potential germination is obtained. In this review article the cold plasma treatment for various plants and their effects are included. More focus is given on the effect on seed germination. Thus this paper shall provide a brief idea on impact of non-thermal plasma treatment on seeds.
