This study compared the effects of seed treatment with low-pressure cold plasma (CP) and atmospheric dielectric barrier discharge (DBD) on morpho-biochemical traits in Stevia rabaudiana Bertoni plants cultivated by two methods: soil aeroponics. We investigated impact treatments germination, plant growth, content secondary metabolites, namely steviol glycosides (SGs), rebaudioside A (RebA), stevioside (Stev), as well phenolic compounds flavonoids. Seeds were treated for 2, 5, 7 min CP or DBD 5 vacuum six days before sowing. All growth parameters aeroponics exceeded seedlings corresponding groups soil. Seed stimulated SGs biosynthesis grown soil, except CP7. Although there no stimulating aeroponics, overall SG concentrations considerably higher to soil: RebA+Stev concentration was 1.8–2-fold control, V5-, CP-treated groups, 1.3-fold DBD5 DBD7 groups. Thus, aeroponic cultivation has potential improve synthesis stevia, while a combination only increases antioxidants antioxidant activity.

ABSTRACT This study investigates how varying excitation frequencies (15, 30, 45, and 60 kHz) influence ozone reactive oxygen species (ROS) generation in frequency‐controlled cold atmospheric pressure plasma (EFCAP) plasma‐treated water (PTW) for biomedical applications. Adjusting the frequency alters amplitude of waveform, thereby affecting production ROS. The most pronounced effects occur at 15 kHz, with strong correlations observed between discharge parameters modulation. Furthermore, introduction nitrogen into argon significantly enhances production. These findings offer valuable insights optimizing conditions to improve control over species, advancing development plasma‐based medical treatments.

Plasma-assisted treatment is a potentially interesting technology for advanced seed processing. In this work, we address the issue of defining and quantifying plasma dose during exposure seeds to microdischarges formed in barrier discharge configuration fed with synthetic air at atmospheric pressure. Using imaging other optoelectrical diagnostics, identify suitable conditions formation developing exclusively between powered electrode coat, which allows relatively accurate quantification an individual barley seed. addition determining microdischarge energy/power consumed treat single controlled exposure, also provide estimate electric field gas temperature, are key parameters that can affect viability. way, each individually exposed be linked exact time, total number, energy, temperature came into contact it. This fundamentally different from conventional “averaging” approaches based on simultaneous many seeds, makes it virtually impossible correlate responses corresponding dose. Finally, propose minimal protocol could allow more direct interpretation results subsequent biological tests reveal specific plasma–chemical stimuli germination seedling growth.

In this study, plasma-activated water (PAW) was generated using a large-volume (5 L) plasma reactor with quasi-stationary, water-cathode glow-type discharge in atmospheric pressure air. Tap activated up to 75 min. PAW exhibited high concentrations of long-lived reactive nitrogen species (RNSs), reaching 8 mM, which is between 4 and 26 times higher than those reported previous studies. The reached an RNS synthesis efficiency 61 nmol/J production rate 526 μmol/min, both among the highest reported. evaluated on tomato bell pepper. Seedling emergence determined nutrient-free substrate. To assess plant growth, seedlings were transplanted into pots filled either nitrogen-free or nutrient-rich PAW-irrigation significantly promoted seedling leaf expansion, especially plants. growth-stimulating effects more pronounced substrate: fresh weight pepper increased 13.1-fold 2.6-fold, respectively. contrast, effect substrate negligible. Tomato plants grown irrigated 75-min dry comparable irrigation did not induce oxidative stress, as confirmed by malondialdehyde (MDA) levels antioxidant enzyme activity.
