“…The early stage of water uptake into seeds is the crucial period for seed germination. Previous studies have indicated that a plasmainduced improvement in seed germination was related to the water uptake of seeds [27,28]. In this study, cold plasma treatment markedly increased the water uptake of oilseed rape seed (figure 4).…”

The effects of low-vacuum helium cold plasma treatment on the seed germination, plant growth and yield of oilseed rape (Brassica napus L. cv. Zhongshuang 9) were investigated. Seeds were exposed to low-vacuum helium cold plasma ranging from 0-120 W for 15 s. Cold plasma increased the germination, plant growth and yield of oilseed rape, and the treatment of 100 W provided the best result. The germination rate, germination and vigor indices, and uniformity of emergence were improved by cold plasma treatment. Cold plasma raised the relative conductivity and water uptake, and reduced the apparent contact angle. The characteristics of plant growth, including plant height, stem diameter, dry weights of shoot and root at the seedling, bolting and flowering stages were increased by the cold plasma treatment. Yield components, including pod numbers per plant and 1000 seed weights were increased by the cold plasma treatment. Furthermore, the yield per plant increased by 28.20%. These results suggest that cold plasma treatment has the potential to improve the yield of oilseed rape through the enhancement of permeability, wettability and capacity of water uptake of the seeds, seed germination and plant growth.

“…These processes occur through the adsorption of the functional groups originated from the interaction between free radicals produced by plasma and the constituent elements of the integument. This way, there is increased absorption of water by the seeds (LING et al, 2014;BORMASHENKO et al, 2015;ZAHORANOVA et al, 2016;ALVES JÚNIOR. et al, 2016b;SIVACHANDIRAN;KHACEF, 2017).…”

-Plasma technology is a fast, cost-effective, and pollution-free method that can be used in place of conventional methods to overcome seed dormancy. The goal of the present study was to determine the effect of different application times of atmospheric plasma on soaking and germination of Hybanthus calceolaria seeds in order to accelerate these processes. Helium plasma jet produced by dielectric barrier discharge was used to treat H. calceolaria seeds with applications of 1, 5, and 10 minutes. The treated seeds were characterized considering their weight variation during soaking, changes in electrical conductivity, and pH. It was found that germination depended on the plasma application time. The treatment of H. calceolaria seeds with atmospheric plasma for 1 minute provided 3.5 times greater germination in comparison to untreated seeds. Atmospheric plasma technology obtained by dielectric barrier discharge had potential of being used as a germination accelerant in H. calceolaria seeds. The treatment of H. calceolaria seeds using atmospheric plasma for 1 minute favored germination.

“…Studies have shown that discharge plasma can increase the germination, growth and yield of various plant seeds such as pea, wheat, tomato and Andrographis paniculata [14][15][16][17], it can improve the hydrophilicity of the surface of soybean seeds, thereby increasing the germination speed of seeds [18], it etches the wheat seed coat, which leads to an increase in water absorption capacity [19], it can reduce the apparent contact angle of Erythrina velutina (mulungu) seeds and change the hydrophilicity of seeds [20]. The interaction between HVEF and an organism is very complex, in order to explore the role and contribution rate of the two factors in HVEF, when naked oat seeds were treated, one group was exposed directly, the other group was covered with a petri dish cover (blocking the influence of ion wind, the result can be approximated by the electric field single factor effect).…”

In order to study the mechanism of high-voltage electric field (HVEF) biotechnology, corona discharge produced by a multi-needle-plate HVEF was used to treat naked oat seeds, each treatment dose was divided into two groups, one group was covered with a petri dish cover, the other group was directly exposed to HVEF without a petri dish cover. The scanning electron microscope (SEM) results show that the etching degree of the uncovered group was more serious than that of the covered group, it indicates that ion wind etching has a greater impact on the micro-morphology of seed coat, being covered can effectively reduce the etching degree of discharge plasma on seed. Fourier Transform infrared spectroscopy (FTIR) of the seed coat shows most of the HVEF treatment group can form a new absorption peak at 1740 cm−1, which is closely related to the hydrophilicity of the seed. Comprehensive analysis shows that HVEF treatment can improve the hydrophilicity of seeds, whether they are covered or not. Being covered can reduce the degree of etching of the seed coat, but increase the hydrophilicity of the seed, indicating that the non-uniform electric field has a greater impact on the hydrophilicity of the seed. Our study showed that ion wind had an effect on the micro-morphology of seeds, but this effect didn’t translate into a macroscopic effect. This study provides ideas and experimental data support for the study of the biotechnological mechanism of HVEF.
