“…Typically, seeds are hydrophobic by nature. When seeds are exposed to CAPP for a certain period of time, reactive species (RONS) present in the CAPP may be implicated in the surface etching of the seed coat, which enhances the roughness of the seeds and causes them to become more granular, as reported by several researchers using SEM micrographs [37,54,55]. When the reactive species interact with the seed coat, they may result in the etching of a waxy layer from the surface of the seed coat (testa).…”

Cold plasma is an innovative and promising technology that is developing in a variety of fields, and recently it has been getting a lot of attention in the agricultural industry. The influence of cold atmospheric pressure plasma (CAPP) exposure on germination parameters and vigor of radish (Raphanus sativus) and carrot (Daucus carota sativus L.) seeds was investigated in the present study. A custom-designed plasma driver utilizing 11.32 kV rms and 50 Hz was used for the generation of the discharge. Seeds were treated using a dielectric barrier discharge (DBD) in an argon atmosphere at exposure periods of 1–4 minutes. The estimate of plasma parameters was done using optical emission spectroscopy and electrical measurements. Germination-related measures such as the final germination percentage, germination index, germination value, coefficient of velocity of germination, vigor index, and chlorophyll content were all improved in the case of CAPP-treated seeds as compared to control seeds. Similarly, CAPP treatment changed the in vitro radical scavenging capabilities, total phenolic, and total flavonoid levels of the seedlings. Our results indicated that the seeds being treated by CAPP for 3 minutes seemed to have a favorable impact on seed germination and sprouting development.

“…[21][22][23][24][25][26] Atmospheric pressure non-thermal plasma, considered by its highly energetic electrons, generates sufficient reactive species without inducing thermal damage to the treated surfaces. [27][28][29][30][31] These reactive species play a crucial role in mitigating pathogenic contamination and stimulating plant growth. In a previous study, we introduced a novel atmospheric pressure non-thermal plasma source known as LF-microwave hybrid plasma (LFMHP).…”

“…In a previous study, we introduced a novel atmospheric pressure non-thermal plasma source known as LF-microwave hybrid plasma (LFMHP). [28][29][30][31] This hybrid plasma combines a low-frequency (LF) plasma jet (PJ) combined with a source of microwave plasma, resulting in an expanded plasma discharge. Compared to conventional LF-PJ, the LFMHP exhibits a higher concentration of reactive species.…”

“…This is achieved through the accelerated motion of higher-energy electrons, facilitated by the oscillating electric fields of the microwave. [28][29][30][31] This elevated concentration of reactive species, comprising reactive oxygen species (ROS) and reactive nitrogen species (RNS), is contemplated to hold the potential for reducing pathogenic contamination on seed surfaces and stimulating plant growth. [31][32][33] Despite these potential benefits, the flexibility of atmospheric pressure non-thermal plasma may not enable uniform treatment of the entire plant surface, and inappropriate operation can potentially harm the plant surface.…”

The current study intends to examine the impact of non-thermal plasma generated by a low-frequency microwave hybrid plasma (LFMHP) on the germination and growth of radish (Raphanus sativus L.) sprout seeds. Plasma activated water (PAW) was utilized as part of the experimental approach for this investigation. The chemical indicator (CI) analysis revealed that the LFMHP generated a significantly higher concentration of reactive oxygen species (ROS) compared with the conventional LF plasma jet (LF-PJ). The application of LFMHP treatment on PAW led to higher germination percentages and improved germination potential in radish sprout seeds compared to both the LF-PJ and control group treatments. Additionally, the average length of radish sprouts treated with PAW using the LFMHP was longer in comparison to those treated with PAW using the LF-PJ and the control group. The findings from this study suggest that PAW treated with LFMHP enhances both the germination and plants growth. Furthermore, this study observed that NO3 - shows a crucial role in influencing the growth rate of radish sprouts.

“…Following the promotion of crop growth, biomass yield, branching, seed ripening, and better disease resistance, the use of cold plasma has beneficial effects on seed disinfection and sprouting [18]. Tonmitr et al exposed seedlings to admixture discharge gas of Ar-O 2 and showed that the LF microwave hybrid plasma produced more reactive oxygen species than a traditional LF plasma jet [19]. According to analysis using SEM, the wettability of the radish seed was modified by etching effects on the seed coat that followed the argon plasma treatments [20].…”

The process of seed germination is described as the culmination of a series of events that start with wetting and end with the emergence of the embryo (typically the radicle) from the seed coat. This method has an impact on crop output and quality. The characteristics of the seed surface and the surroundings have an impact on the kinetics and volume of water absorption by seeds. As a result, modifying the characteristics of a seed's surface is a useful tactic for influencing seed germination. Low-temperature plasma (LTP) treatment of the seed for surface activation is now being researched as an effective pre-sowing technique. This study looked at the effects of LTP on radish (Raphanus sativus) seeds at room temperature for various times. The seed's germination properties, growth parameters, water contact angle (WCA), Scanning Electron Micrograph (SEM), and FTIR analysis were examined. WCA and SEM examination revealed a considerable alteration in the seed coat following LTP treatment, which is directly connected to water permeability into the seeds. Similarly, FTIR analysis confirmed that the enhancement of the hydrophilic properties of the seeds following plasma treatment is likely due to the damage of the hydrophobic moieties on the seeds' surface. The LTP treatment improved each germination-related parameter, including the vigor index, chlorophyll content, in-vitro radical scavenging activities, total flavonoid, and phenol in the seedlings. Our findings indicate that LTP treatment has a beneficial impact on early seed sprouting and the development of radish.
