“…The seeds immersed into air plasma is subjected to reactions with electrons, ions, reactive species, and UV light emitted by the discharge. This hypothesis supports that the plasma treatment induces changes on the seed surface 36 and allows radicals to penetrate into the seed and affect the metabolic process of plant growth as shown by Sera et al 15 for wheat and oat treatment. Moreover, the quality of water may play a major role on improving the plants development by providing chemical species.…”

The combined effect of non-thermal plasma treatment of water and seeds on the rate of germination and plants growth of radish (Raphanus sativus), tomato (Solanum lycopersicum), and sweet pepper (Capsicum annum) have been investigated using dielectric barrier discharges in air under atmospheric pressure and room temperature. A cylindrical double dielectric barrier discharge reactor is used for water activation and a plate-to-plate double DBD reactor is employed for seed treatment. The activation of water, for 15 and 30 min, lead to acidic solutions (pH z 3) with moderate concentrations of nitrate (NO 3 À ) and hydrogen peroxide (H 2 O 2 ). Plasma activated water (PAW) has shown a significant impact on germination as well as plant growth for the three types of seeds used. Interestingly, the positive effect, in seed germination and seedling growth, has been observed when the PAW and plasma-treated seeds (10 and 20 min) were combined. In one hand, when the seeds were (tomato and pepper) exposed to 10 min plasma and watered with PAW-15 for first 9 days followed by tap water for 51 days, the stem length is increased about 60% as compared to control sample. On the second hand, for longer exposures of seeds and water to plasma discharges, a negative effect is observed. For instance, plasma-treated seeds watered with PAW-30, the plant growth and vitality were decreased as compared to control sample.These results revealed that the developed cold plasma reactors could be used to significantly improve the seed germination as well as plant growth, nevertheless, the plasma treatment time has to be optimized for each seeds.

“…Recently, studies show that cold atmospheric plasma systems could promote seed germination and growth [1,[3][4][5][6][7][8][9][10][11][12][13][14][15]. Increment seed germination rate, growth development, and crop yield by plasma treatment have been reported in various crops: spinach [16], wheat [8,13], soybean [9], and radish [17]. Cold atmospheric plasma systems consist of positively and negatively charged particles (free electrons and ions), and neutral activated species including excited molecules, UV photons, long and short lived free radicals, reactive oxygen species, reactive nitrogen species, and some ozone [18].…”

Recently, cold atmospheric plasma (CAP) with the unique bio-disinfection features is used in various fields of industry, medicine, and agriculture. The main objectives of this work were to design FSG plasma (a semi-automatic device) and investigate the effect of the cold plasma in the enhancement of the Pea and Zucchini seed germination. Plasma irradiation time was studied to obtain a proper condition for the germination enhancement of seeds. The growth rate was calculated by measuring length of root and stem and dry weight of plants treated by plasma. To investigate drought resistance of plants, all treated and untreated samples were kept in darkness without water for 48 h. From the experimental results, it could be confirmed both drought resistance and germination of seedlings increased after plasma was applied to seeds at 30 s, while seeds treated whiten 60 s showed a decrease in both germination rate and seedling growth.

“…It is obvious, that plasma treatment infl uences morphological and sowing characteristics of seeds in different ways [ 6 ] due to the complexity of plasma producing fl uxes of various neutral or ionized active species as well as energetic photons interacting with treated samples. Seeds are an extremely complex biological system and vitally important biochemical processes may be affected by plasma or electromagnetic treatment in a number of different ways.…”
