“…To improve seed absorption, plasma treatment is expected to have positive effect on germination. This would correlate with the published results (Bafoil et al, 2018;Štěpánová et al, 2018;Magureanu et al, 2018;Guo et al, 2018;Los et al, 2018). A 15 s plasma treatment did not affect germination but stimulated the growth parameter of the seeds of both cereals.…”

In order to reduce the environmental burden of chemicals, various new alternatives to seed protection are being sought. Our aim was to find an environmentally acceptable solution leading to the inactivation of seed-borne phytopathogenic fungi Fusarium culmorum on the surface of wheat and barley seeds with a positive effect on their germination. As a low-temperature plasma (LTP) source, a Diffuse Coplanar Surface Barrier Discharge (DCSBD) was used. Plasma generated by DCSBD is non-equilibrium, cold, diffuse, macroscopically homogeneous even in ambient air at atmospheric pressure. Experimental results showed that LTP treatment in the range of 120—300 s significantly inhibits the growth of F. culmorum on the surface of the seeds. The efficiency of LTP treatment was compared with traditional seed protection processes using chemical fungicide and also with combined seed pretreatment by plasma and subsequent application of chemical fungicide. No growth of F. culmorum was observed after the combination of Vitavax 2000 fungicide application in the dose of 10 % and 60 s of LTP treatment even on the 5th day of incubation. Better wettability of seeds with the chemical fungicide was related to the change on seed surface, which becomes hydrophilic after 10 s of LTP application. Short LTP exposure times did not affect germination and improved the growth parameter of cereal seeds. By combining physical (LTP) and chemical (Vitavax 2000) treatments of cereal seeds, it is possible to effectively reduce the required amount of chemical fungicide and to stimulate germination and early growth seed parameters.

“…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.

“…Numerous works have shown that non-thermal plasma is a fast, uniform, economic, effective, and eco-friendly approach for stimulating seed germination and seedling growth compared with the conventional seed pretreatment methods, e.g. ultraviolet and gamma radiation, scarification, hot water soaking, and chemical reagent treatment (Li et al, 2014; Randeniya and De Groot, 2015; Mildaziene et al, 2018; Štěpánová et al, 2018). In the last years many authors studied the stimulation of the seed germination and the plant growth by using plasma generator (Živković et al, 2004; Šerá et al, 2010; Dobrin et al, 2015; Bafoil et al, 2018).…”

Non-thermal plasma holds great potentials as an efficient, economical, and eco-friendly seed pretreatment method for improving the seed germination and seedling growth, but the mechanisms are still unclear. Therefore, a plant model organism Arabidopsis thaliana was used to investigate the physio-biochemical responses of seeds to non-thermal plasma at different treatment times by measuring the plant growth parameters, redox-related parameters, calcium (Ca2+) level and physicochemical modification of seed surface. The results showed that short-time plasma treatment (0.5, 1, and 3 min) promoted seed germination and seedling growth, whereas long-time plasma treatment (5 and 10 min) exhibited inhibitory effects. The level of superoxide anion (O2•−) and nitric oxide (NO) and the intensity of infrared absorption of the hydroxyl group were significantly higher in short-time plasma treated Arabidopsis seeds, and the level of hydrogen peroxide (H2O2) was remarkably increased in long-time plasma treated seeds, indicating that O2•−, ·OH, and NO induced by plasma may contribute to breaking seed dormancy and advancing seed germination in Arabidopsis, while plasma-induced H2O2 may inhibit the seed germination. The intensity of hydroxyl group and the contents of H2O2, malondialdehyde, and Ca2+ in Arabidopsis seedlings were obviously increased with the plasma treatment time. Catalase, superoxide dismutase, and peroxidase activities as well as proline level in short-time treated seedlings were apparently higher than in control. The etching effects of plasma on seed surface were dose-dependent, spanning from slight shrinkages to detached epidermis, which also significantly increased the oxidation degree of seed surface. Therefore, the improved activities of antioxidant systems, moderate ·OH, H2O2, and Ca2+ accumulation and seed surface modification induced by plasma all contribute to the enhanced seedling growth of Arabidopsis after short-time plasma treatment.
