“…In three other cases, similarly to our results, the germination percentage was unchanged. In the case of treatment with an argon plasma jet, germination was already 100% in untreated seeds [17]. In another treatment with an IC RF air plasma [16], as well as in a seed-packed DBD reactor with helium [18], germination of untreated seeds was also >90%, and the plasma treatment accelerated the germination in both cases.…”

“…Furthermore, when the seeds were planted in soil, an increase in seedling length emerging from the soil was found after plasma exposure [36]. Seedling vigor, which is a measure of both seedling length and germination percentage, was also improved after an argon plasma jet treatment [17]. Similar improvements after plasma treatment were also observed in soybean, where one group has demonstrated that a DBD treatment of seeds may improve a variety of growth and physiology parameters in healthy seeds as well as those infected with a fungal complex [55].…”

“…Inductively coupled (IC), radio frequency (RF) air plasma has increased the germination percentage [15] and accelerated the germination [16] of bean seeds within 15 to 120 s of treatment. The seed vigor also increased through the treatment of a single seed with an argon plasma jet for 30-180 s [17]. At 5 min, the shortest treatment time in the oxygen DBD experiment, the treatment also increased hypocotyl and radicle length, but prolonged treatment inhibited germination [14].…”

Seeds of common bean (Phaseolus vulgaris L.), of the Etna variety, were treated with low-pressure oxygen plasma sustained by an inductively coupled radiofrequency discharge in the H-mode for a few seconds. The high-intensity treatment improved seed health in regard to fungal contamination. Additionally, it increased the wettability of the bean seeds by altering surface chemistry, as established by X-ray photoelectron spectroscopy, and increasing surface roughness, as seen with a scanning electron microscope. The water contact angle at the seed surface dropped to immeasurably low values after a second of plasma treatment. Hydrophobic recovery within a month returned those values to no more than half of the original water contact angle, even for beans treated for the shortest time (0.5 s). Increased wettability resulted in accelerated water uptake. The treatment increased the bean radicle length, which is useful for seedling establishment in the field. These findings confirm that even a brief plasma treatment is a useful technique for the disinfection and stimulation of radicle growth. The technique is scalable to large systems due to the short treatment times.

“…The direct treatment of seeds is predominantly performed with dielectric barrier discharges (DBDs) in ambient air. [ 51,65–92 ] The seeds are, thus, exposed to a variety of long‐ and short‐lived RONS (e.g., O, OH, O 3 , H 2 O 2 , N, NO, NO 2 − , NO 3 − ) and, in the case of volumetric DBDs (VDBD), to ions and the electric field. [ 93 ] Most studies report plasma dose‐dependent increased germination rate, increased root length, and enhanced growth of the seedlings.…”

Plasma agriculture details the role of nonthermal plasma in the development of plants from seeds to crops. Several publications reported enhanced plant growth, improved stress tolerance, and antimicrobial effects of plasma treatment and plasma‐treated water. In this review, we present an overview of the recent plasma agriculture literature and put it in the context of the plant needs and the effects on the plant ecosystem. We will discuss key developmental stages of plants and their needs, the different growth environments from hydroponics to soilless and soil substrates, and the plant microbiome. This review provides the context to design plasma‐based fertilization strategies to address the needs of plants and their ecosystem.
