Plasma also called as ‘fourth state of matter’ encompasses ionized gas, atoms, free molecules, radicals and free electrons. Considering its discovery in late 19th century plasma is extensively used as low pressure or high pressure plasmas in many applications commercially such as microelectronic technology, textile industry, organic waste management etc. When a gas is passed through an electric field in a plasma chamber, three types of collisions are known to take place in it particularly, excitation, ionization and deposition that provide plasma its characteristic glow, ion-electron pair, reactive species respectively. Plasma treatment of different object can change their chemical and physical properties. In Seed Science and Research, many seed quality enhancement techniques are used to improve seed quality in crop plants such as, seed priming, fortification, solid matrix priming, chemical treatment, hardening etc. Plasma treatment of seeds is a unique tool that utilizes an ionized gas to modify the physical and chemical properties seed viz., wettability, porosity, water absorption, activity of antioxidant enzymes. It can also decontaminate the seed surface off micro flora and convert hydrophobic seeds to hydrophilic. It also enhances soluble sugar content, protein content and causes a reduction in lipid peroxidation. Thus plasma treatment in turn improves seed germination rate, seedling characteristics, seed physical quality and seed health.
