What is Germination

The reclamation of new areas or distant lands, which have limited energy and material resources, requires the use of energy saving technologies, which include presowing processing of seeds in magnetic field. The aim of this chapter is to reveal the effect that magnetic field has on seeds and to detect the most effective condition to process seeds in magnetic field before sowing and constructive parameters of the equipment. Magnetic field accelerates chemical reactions, which occur in plant cells, salts and fertilizers dissolve better, and the permeability of cell membranes increases, which accelerates the diffusion of molecules and ions. Due to this, the concentration of ions and oxygen molecules in a cell increases and seeds absorb water better. Presowing processing of seeds stimulate 25–40% seedling emergence and 30–35% germination. The most effective condition of presowing processing of seeds in magnetic field is 0.065 Тl magnetic induction with four times magnetic reversal and 0.4 m/s seed velocity. As a result, agricultural crop yield increases approximately by 20–25%.
