“…The positive effect of NTP on growth was associated with the accumulation of proteins involved in the regulation of cell growth and division, such as growth-regulating factor ( GRF ) and serine/threonine protein kinase TOR was observed in the leaves of sunflower seedlings [ 169 ]. In the related field of plasma application, an increase in root hair density was associated with PAW-enhanced growth of Arabidopsis seedlings, and the relationship of this phenomenon with the function of COBRA-like 9 involved in root hair development and the cell wall modification enzymes xyloglucan endotransglycosylases/hydrolases XTH9 and XTH17 was confirmed by gene expression analysis [ 204 ].…”

Among the innovative technologies being elaborated for sustainable agriculture, one of the most rapidly developing fields relies on the positive effects of non-thermal plasma (NTP) treatment on the agronomic performance of plants. A large number of recent publications have indicated that NTP effects are far more persistent and complex than it was supposed before. Knowledge of the molecular basis and the resulting outcomes of seed treatment with NTP is rapidly accumulating and requires to be analyzed and presented in a systematic way. This review focuses on the biochemical and physiological processes in seeds and plants affected by seed treatment with NTP and the resulting impact on plant metabolism, growth, adaptability and productivity. Wide-scale changes evolving at the epigenomic, transcriptomic, proteomic and metabolic levels are triggered by seed irradiation with NTP and contribute to changes in germination, early seedling growth, phytohormone amounts, metabolic and defense enzyme activity, secondary metabolism, photosynthesis, adaptability to biotic and abiotic stress, microbiome composition, and increased plant fitness, productivity and growth on a longer time scale. This review highlights the importance of these novel findings, as well as unresolved issues that remain to be investigated.

“…The foliar application of the PAW significantly (p ≤ 0.05) increased the C R value by 14.6% compared to the DW treatment. An enhanced root production during the early developmental stages after the PAW application was observed at Vigna radiata [45] or Nicotiana tabacum [46]. A significant increase of the root weight of Vigna mungo whose seeds were treated by the PAW was reported in [47].…”

Utilization of plasma activated water (PAW) for plant growing is mainly connected with the treatment of seeds and subsequent stimulation of their germination. A potential of PAW is its relatively simple and low-cost preparation that calls for studying its wider application in plant production. For this purpose, a pot experiment was realized in order to prove effects of the foliar PAW application on maize growth. The stepped PAW foliar application, carried out in 7-day intervals, led to provable decrease of chlorophyll contents in leaves compared to the distilled water application. The PAW application significantly increased root electrical capacitance, but it had no provable effect on weight of the aboveground biomass. Chlorophyll fluorescence parameters expressing the CO2 assimilation rate and variable fluorescence of dark-adapted leaves were provably decreased by PAW, but quantum yield of photosystem II electron transport was not influenced. A provably higher amount of nitrogen was detected in dry matter of plants treated by PAW, but contents of other macro- and micro-nutrients in the aboveground biomass of maize were not affected. Results of this pilot verification of the PAW application have shown a potential for plant growth optimization and possibility for its further utilization, especially in combination with liquid fertilizers.

Plasma agriculture has recently gained popularity owing to its potential applications in precultivation, cultivation, and postharvest processes. Plasma treatments are beneficial seed-priming agents for improving seed germination. The increase plant growth during the seedling stage and enhance fruit storage duration during postharvest treatment. However, little research has been conducted to confirm the long-term effects of plasma-activated water (PAW) treatment on plant cultivation during stages from germination to harvest. Here, we demonstrate the utilization of PAW, generated from a single dielectric barrier discharge (SDBD) device, to understand the functional role of PAW in the cultivation of tomato ‘Micro-Tom’, from germination to harvest. PAW treatment enhanced the growth of young seedlings and increased the number of flowers, plant biomass, and yield compared with the control. Moreover, no adverse effects on the characteristics of fruits produced by PAW-treated plants were observed. These results highlight the potential of PAW as an alternative ecofriendly nutrient source for plant irrigation under nutrient-limiting conditions, during all the stages from seeds to fruits, and offer promising implications for future agricultural practices.
