“…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.

“…Filatova et al treated cereal and legume seeds in a capacitively‐coupled low‐pressure (40–80 Pa) RF air discharge plasma (frequency 5.28 MHz and specific power 0.34–0.65 W · cm 3 ) . The seeds of spring wheat ( Triticum aestivum L.), narrow‐leaf lupine ( Lupinus angustifolius ) and corn ( Zea Mays L.) were exposed to plasma for periods of up to 10 min.…”

“…The efficiency of the plasma treatment was determined by measuring the laboratory germination viability and biometric indicators (shoot length). Filatova et al observed the spectra for molecular bands of N 2 and its positive and negative molecular ions, NO and OH for discharges with low power (≤0.5 W · cm −3 ) . The seeds treated at this low power showed no visible changes in colour or texture.…”

The presence of pathogens and other stresses at germination and seedling stages affect the successful establishment of crops. The use of non-thermal plasma is a new approach to reduce such stresses. Plasma can interact with seeds and change their surface characteristics by etching, introducing functional groups and coating with exotic materials. Emerging evidence indicate that plasma treatment of seeds can enhance germination and seedling growth in crops by removal of microbial layers, changes in water uptake and other changes. Here, we review the status of research and show the potential role that plasma technology can play in addressing the challenges in food production. Major progress is possible by plasma treatments at or near atmospheric pressure where batch processing of large seed samples is possible.

“…The application of the CP in agriculture is either direct (seeds or plants are in a direct contact with plasma) or indirect (seeds or plants are exposed to plasma treated/activated gas or water) . The plasma in direct contact with the seed can stimulate its germination and growth and subsequent fruit yield, change enzymatic activity in developing seeds, change secondary metabolites content, and also reduce phytopathogenic microflora from the seed surface . Plasma can also modify seed surface and change its affinity towards water to either hydrophilic or hydrophobic, that both can be beneficial .…”

The paper presents the study on the effects of the plasma activated water (PAW) generated by transient spark discharge on the wheat (Triticum aestivum L.) cultivated in vitro and in vivo. Water uptake and germination of seeds, growth parameters of seedlings and plants, as well as the content of photosynthetic pigments, soluble proteins and activity of antioxidant enzymes are reported and correlated with the concentrations of reactive oxygen and nitrogen species in the PAW. The PAW improves germination, early development of the seedlings, the content of photosynthetic pigments in the leaves and soluble protein content in the roots, and suppresses the activity of antioxidant enzymes. The results indicate that the PAW may effectively stimulate growth of the wheat seedlings and positively affect their metabolism especially in the soil with low nutrient content.
