Abstract: (4 Views)
Aim and Background: This study was conducted to investigate the effect of zinc nanoparticles and atmospheric cold plasma on the physiological characteristics of wheat during the germination stages. According to previous studies, seed treatment with atmospheric cold plasma affects the germination rate and the morphology of plants, while the use of zinc in nano dimensions leads to increased growth rates.
Materials and Methods: In this study, the effects of different concentrations of zinc oxide nanoparticles and zinc oxide (control without treatment, 10 ppm, 25 ppm, and 50 ppm) were examined every three days, along with atmospheric cold plasma at three time points (0 seconds as control, 60 seconds, and 90 seconds) on 14-day-old wheat seedlings.
Results: According to the results obtained, plasma treatment for 90 seconds significantly increased germination-related indices but resulted in reduced root and shoot length. Additionally, treatment with zinc oxide nanoparticles at a concentration of 25 ppm showed the greatest increase in fresh and dry weight of the seedlings compared to the control.
Conclusion: Plasma treatments elevated germination indices, but the addition of zinc oxide nanoparticle solution to the plants limited this increase. Conversely, nanoparticles at the studied concentrations led to increased dry weight of the seedlings and the length of their roots and aerial parts.Considering that increased wheat seedling growth means more energy is available for root, stem, and seed development, the use of atmospheric cold plasma on wheat seeds and the treatment with zinc nanoparticles at optimal concentrations can enhance plant growth and ultimately improve crop yield.
