“…Moreover, higher concentrations of protein and sugar were observed by Islam et al [64] and Billah et al [40] due to an increase in reserve utilization enzymes. Billah et al [40] explained that this could be because H 2 O 2 transduces the signal for soluble sugar synthesis and therefore, more soluble sugar and protein are seen after plasma treatment [62]. Moreover, exogenous treatment with H 2 O 2 can stimulate germination by breaking dormancy through the oxidative pentose phosphate pathway, which provides reducing power and carbon for the new growth [176].…”

Mechanisms of Plasma-Seed Treatments as a Potential Seed Processing Technology

2021

Plasma treatments are currently being assessed as a seed processing technology for agricultural purposes where seeds are typically subjected to pre-sowing treatments to improve the likelihood of timely and uniform germination. The aim of this review is to summarize the hypotheses and present the evidence to date of how plasma treatments affect seeds, considering that there is difficulty in standardizing the methodology in this interdisciplinary field given the plethora of variables in the experimental setup of the plasma device and handling of biological samples. The ever increasing interest for plasma agriculture drives the need for a review dedicated to seeds, which is understandable to an interdisciplinary audience of biologists and plasma physicists. Seeds are the first step of the agricultural cycle and at this stage, the plant can be given the highest probability of establishment, despite environmental conditions, to exploit the genetic potential of the seed. Furthermore, seedlings seem to be too sensitive to the oxidation of plasma and therefore, seeds seem to be the ideal target. This review intentionally does not include seed disinfection and sterilization due to already existing reviews. Instead, a summary of the mechanisms of how plasma may be affecting the seed and its germination and developmental properties will be provided and discussed.

This study aimed to investigate the effects of dielectric barrier discharge cold atmospheric plasma on the performance of basil (Ocimum basilicum L. cv. Genovese Gigante). Evaluations were carried out on several physiological and biochemical traits, including ion leakage, water relative content, proline and protein accumulation, chlorophyll and carotenoid contents, and antioxidant activity. Before planting, basil seeds were treated by cold atmospheric plasma under voltages of 10, 15, and 20 kV for 10, 20, and 30 min. The ion leakage rate in plants was significantly affected by the interaction between plasma and radiation time. In most treatments, the application of plasma significantly reduced the ion leakage rate. The application of plasma (10 and 20 kV) for 10 min significantly increased the relative water content of basil leaves. The maximum amount of total chlorophyll and carotenoid content occurred after applying plasma for 20 min with 15 kV. Furthermore, 10 and 15 kV treatments of atmospheric cold plasma for 10 min caused a significant increase in antioxidant activity. The highest total flavonoids were obtained after applying 15 kV treatments for 20 min and 20 kV for 30 min, respectively. Cold atmospheric plasma significantly increased the activity of peroxidase as an antioxidant enzyme. Moreover, the minimum and maximum values of microbial load based on logarithm ten were reached after applying 10 kV for 30 min and in the control group, respectively. In general, the results showed that dielectric barrier discharge cold atmospheric plasma could significantly improve basil plants’ physiological and biochemical traits.

“…Mung bean sprouts are widely consumed as one of the most popular vegetables for their greater health benefits and fewer calories. In decade years, numbers of physical, chemical, and combination intervention strategies have been implemented to stimulate seeds germination and production of bean sprouts [1,2], such as gamma irradiation, ultrasound, X-irradiation, electromagnetic field, cold plasma, electrolyzed oxidizing water, and pesticides [3,4]. However, these technologies are associated with multiple serious adverse effects, such as high cost, time consuming, leaving chemical residues to environment, and raising ecological issues.…”

The present work aimed to investigate the effect of plasma-activated water (PAW) on seed germination and seedling growth of mung bean sprouts. Distilled water was exposed to non-thermal plasma for 15, 30, 60, and 90 s to prepare PAW, which was defined as PAW15, PAW30, PAW60, and PAW90, respectively. The germination rate, growth characteristics, total phenolic and flavonoid contents were all maximized when mung bean seeds were treated by PAW15, then followed by a decline over the prolonged plasma activation time (30-90 s). PAW15 caused no remarkably changes in the antioxidant capacity of sprouts as compared to DW (p > 0.05). However, the antioxidant activity of sprouts prepared with PAW30, PAW60, and PAW90 were decreased significantly (p < 0.05) compared with that of sprouts soaked in distilled water. In summary, PAW may be used to improve the production of sprouts, but the process parameters should be optimized for each application.
