Due to its carbohydrate and protein content, wheat is one of the most important sources of human food, and the global demand for wheat is increasing along with population growth. The seeds that germinate and settle earlier, have a high efficiency in water absorption and optimal use of soil nutrients.
Pretreatment is a method by which the seeds are physiologically and biochemically more ready for germination before being placed in the soil and facing the ecological conditions of the environment. Simulation and Construction of a rotating chamber based on the uniform treatment of seeds under the non-thermal argon glow discharge plasma, tried to create better control conditions compared to other conventional pretreatment methods. Energetic electrons, ions and active radicals in the plasma collide with the surface of the seed and give it the energy needed to break its bonds, so absorb water and nutrients more easily to accelerate growth. In plasma processing, by creating cracks on the seed surface, faster absorption of water and nutrients occur, therefore germination occurs earlier. According to the results of pre-treated seeds in this chamber and the analysis of the plasma spectrum at three voltages of 800, 600 and 1000 volts in 20, 40 and 60 minutes, we understood that the glow discharge plasma was formed in this chamber, at a voltage of 800 volts and 40 minutes has the most optimal conditions for achieving the germination of wheat seeds. as well as increasing the voltage and time the growth of the length of the seed and germination will increase and by increasing the time more than 40 minutes, plasma pretreatment had a positive result on less number of seeds. It should be noted that no change in the genetic structure of plants in plasma treatment has been reported yet.
