Designing a plasma device and its application on plant medium

Abstract In this research,a corona plasma discharge device is designed and used on the plant medium in ambient air. Furthermore, the kinetic theory of plasma is utilized and its energy and drift velocity impact on the plant atmosphere analytically is investigated in the modeling section. The effect of cyclotronic frequency, and plasma particle drift velocity on particle energy and its distribution during the collision with the plant surface as an essential factor for the germination process is analyzed. This transfer of energy appears as the kinetic energy of the particles and can be explained in the form of the required energyto prepare an appropriate growth atmosphere for the seeds. The higher plasma particle drift velocity leads to higher energy distribution on the seed surface. The effect of low-temperature pulsed plasma application period and direction on the germination and growth rate of seeds are investigated. Dry chickpea seeds are taken into consideration to be the outturn of the same farm and stored in the same barn and condition. The seeds are exposed to plasma at time intervals of 3,7, and 12 minutes. The results showthat the seeds with 7 minutes of plasma treatment had better growth and rejuvenation compared to the control sample and other samples. The 3-minute plasma application to samples decreased the germination and growth. Additionallyseeds are treated by plasma beam from the germination site (embryo),the back of the embryo, and the cotyledons. The results indicate that applying plasma to the embryo enhances the growth of the chickpea seeds after 30 days of observation.
