“…These stable reactive RONS species are suspected for playing a key role in seed dormancy and germination control. 15,33,41,58 Similarly, when discharge time increased, the pH of PAW notably decreased. After 10 min of plasma activation, the pH of the treated water decreased to 4.45 ± 0.05 in comparison to 6.40 for DIW.…”

“…[28][29][30] Most of the researchers reported that the germination rate of seed as well as the plant's propagation will be increased by irrigating them with plasma-treated water. 15,17,[31][32][33] According to Naumova et al, 34 PAW improved germinability of the seeds by 50%. Similarly, Møller et al 35 reported that the seeds irrigated with water containing reactive oxygen species increases seed germination by breaking seed dormancy.…”

The goal of this study is to explore how water treated using plasma affects the germination and growth of soybean and wheat seedlings. Deionized water (DIW) was exposed to a gliding arc discharge (GAD) for 5 and 10 min to create plasma-activated water. DIW revealed significant changes in physical properties as well as chemical parameters after its treatment with plasma. The germination rate (growth metrics, such as shoot/seedling length, imbibition rate of seeds, and vigor indices), increased when plasma-treated water was used for irrigation purposes. In conclusion, when plasma-treated water is used for irrigation, a better result yield in germination is acquired.

“…The rate of seed germination, plant growth, and agricultural yields are all affected by these solutions [24,25]. In plasma agriculture, previously, experiments were performed on the seeds of radish, pea, tomatoes, carrot, and wheat which showed a high increase in the germination percentage and seeding length after plasma treatment [24][25][26][27][28][29][30][31][32][33].…”

Seed germination is a complicated physiological process that starts with the seed absorbing water and concludes with the radicle emerging. The kinetics and amount of water uptake by seeds are known to be influenced by both seed surface properties and the surrounding environment. As a result, altering seed surface features are linked to seed medium and is a valuable strategy for controlling seed germination. In the agricultural field, non-thermal plasma surface activation of seeds is currently being investigated as an efficient pre-sowing treatment for modifying seed germination. The impact of non-thermal plasma (NTP) on the germination and seedling growth of carrot seeds at room temperature and atmospheric pressure for varied treatment times was investigated in this study. Seed's germination properties and growth parameters were examined for both control and NTP treated seeds. Germination-related parameters such as germination percentage, vigor index, and chlorophyll content were all improved by NTP treatment. However, no significant changes were seen in the carotenoid content. Similarly, the in-vitro radical scavenging activities, total phenol, and total flavonoid contents in the seedlings were altered by NTP treatment. Our results indicate that NTP treatment has a favorable effect on carrots germination and seedling development.

One of the innovative and successful approaches for early seed sprouting, and development in an agricultural area is the utilization of non-thermal plasma therapy. In this work, the surface of carrot (Daucus carota sativus L.) seeds was directly treated with low-temperature plasma. Line frequency was used to produce dielectric barrier discharge at an applied ac voltage of 14.87 kV. Carrot seeds were treated under the produced discharge for 1-4 min employing an argon gas flow rate of 2 L/min. Various growth parameters and seed germination properties had been assessed for both untreated and plasma-exposed seeds. Parameters such as final germination percentage, mean germination rate, coefficient of the velocity of germination, germination index, length of root and shoot, fresh weight, diameter, and the number of leaves were found to be increased in plasma-treated seeds. Results from the experiment indicate an increment in vigour index I and vigour index II after plasma treatment. Similarly, significant mass loss and increased water absorption were both observed in the plasma-treated seeds. The study of the results demonstrates that exposing seeds to plasma can be an effective method for the early growth of carrots.
