The atmospheric pressure non-thermal plasma generated by low-frequency (LF)-microwave hybrid discharge has been employed to investigate the effects of plasma treatment on the germination and growth of radish (Raphanus sativus L.) sprout seeds. The plasma generated with admixture discharge gas of Ar-O2 was adopted for the irradiation of seeds. SEM and EDX analyses were performed to elucidate the physical and chemical state changes of seed surfaces after plasma treatment. The reactive species produced in the plasma were investigated using optical emission spectroscopy and chemical indicator. The results demonstrate that higher reactive oxygen species were generated from the LF-microwave hybrid plasma compared to conventional LF plasma jet. Moreover, the higher germination percentage and shorter germination time were obtained with the LF-microwave hybrid plasma compared to LF plasma jet and control group. It is considered that reactive species produced in the LF-microwave hybrid plasma are related to the germination time of the radish sprout seed.

This study conducted an activation experiment on tap water using a self‐designed dielectric barrier discharge plasma field. Aged pepper seeds and seedlings were chosen as the investigation's subjects to assess plasma‐activated water (PAW's) effects on aged seed germination, seedling growth, and their respective qualities. PAW cultivation led to notable improvements in pepper seeds' germination potential and rate, with increases of 18.0% and 28.3%, respectively. Moreover, the vitality index exhibited a remarkable rise of 250.0%. Concurrently, seedlings treated with PAW exhibited significant growth enhancements, with root length, root number, stem length, and leaf area increasing by 138.6%, 69.2%, 47.9%, and 28.4 cm², respectively. Additionally, PAW treatment induces changes in endogenous substances and enzyme activities in seeds and seedlings.

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.
