“…Plasma treatment affects the wettability of the coated seed. Investigations of plasma-induced changes in plant physiology and biochemistry are likely to reveal new facts of fundamental and applied interest (Mildaziene and Sera, 2022). Our findings indicate remarkable responses of wheat seeds and seedlings to plasma.…”

The increased drought and soil salinity are two effects of climate change that threaten global food security and food production. Soil salinity is a major challenge for agriculture in arid areas, creating conditions that may be unsuitable for the growth of crop plants. Here, we use recycled organic tree waste combined with low-pressure plasma treatment as grain coating to improve the ability of Egyptian wheat seeds (Misr-1 and Gemme-za-11) to survive, germinate and produce seedlings in highly saline soil. We coated the seeds with biofilms of lignin and hash carbon to form a protective extracellular polymeric matrix and then exposed them to low-pressure plasma for different periods of time. The effectiveness of the coating and plasma was evaluated by characterizing the physical and surface properties of coated seeds using X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), nuclear magnetic resonance (NMR) spectroscopy, and wettability testing. We also evaluated biological and physiological properties of coated seeds and plants they produced by studying germination and seedling vigor, as well as by characterizing fitness parameters of the plants derived from the seeds. The analysis revealed the optimal plasma exposure time to enhance germination and seedling growth. Taken together, our study suggests that combining the use of recycled organic tree waste and low-pressure plasma may represent a viable strategy for improving crop performance in salty environments.

“…Moreover, the PAW creates a higher amount of hydrogen peroxide (H 2 O 2 ) and nitric oxides (NO), longer half-life molecules which may alter the phytohormone balance in the seeds and promote germination [ 49 ]. Recently, Mildaziene and Sera [ 50 ] and Priatama et al [ 51 ] observed that the accumulation of ROS and RNS triggers changes in proteomic, metabolomic and transcriptomic levels and also affects phytohormone levels. The cavitation bubbles which occur during the HVED treatment create UV emission which could also be meritorious for germination dormancy disruption [ 9 , 44 ].…”

High voltage electrical discharge (HVED) is an eco-friendly low-cost method based on the creation of plasma-activated water (PAW) through the release of electrical discharge in water which results in the formation of reactive particles. Recent studies have reported that such novel plasma technologies promote germination and growth but their hormonal and metabolic background is still not known. In the present work, the HVED-induced hormonal and metabolic changes were studied during the germination of wheat seedlings. Hormonal changes including abscisic acid (ABA), gibberellic acids (GAs), indol acetic acid (IAA) and jasmonic acid (JA) and the polyphenol responses were detected in the early (2nd day) and late (5th day) germination phases of wheat as well as their redistribution in shoot and root. HVED treatment significantly stimulated germination and growth both in the shoot and root. The root early response to HVED involved the upregulation of ABA and increased phaseic and ferulic acid content, while the active form of gibberellic acid (GA1) was downregulated. In the later phase (5th day of germination), HVED had a stimulatory effect on the production of benzoic and salicylic acid. The shoot showed a different response: HVED induced the synthesis of JA_Le_Ile, an active form of JA, and provoked the biosynthesis of cinnamic, p-coumaric and caffeic acid in both phases of germination. Surprisingly, in 2-day-old shoots, HVED decreased the GA20 levels, being intermediate in the synthesis of bioactive gibberellins. These HVED-provoked metabolic changes indicated a stress-related response that could contribute to germination in wheat.

“…Currently, there are a large number of ways to obtain low-temperature plasma [1]. Such plasma is widely used in natural sciences, such as chemistry, physics, biology, medicine and agriculture [2][3][4]. It is known that low-temperature plasma interacts with various molecules, including biological ones [5].…”

The microwave setup for obtaining plasma-activated water (PAW) has been created. PAW contains significant concentrations of H2O2 and NO3−, has a reduced content of O2, high conductivity, a high redox potential and low pH. Likewise, the specific electrical conductivity and concentration of H2O2 and NO3− linearly depend on the treatment time. These parameters are simple and convenient markers for controlling the preparation of PAW. It has been established that PAW solutions with a concentration of 0.5–1.0% increase the germination energy, protect against fusarium and hyperthermia in cotton, wheat and strawberry seeds. In addition, PAWs have a positive effect on the growth rate of plants in the early stages of development. The use of PAW provides significant benefits over the chemical preparations Dalbron and Bakhor, so-called seed germination stimulators (SDS).
