Abstract

The use of pre-sowing treatment of flax seeds in a magnetic field makes it possible to increase yields, reduce plant morbidity, increase their biochemical parameters and product quality. When treatment flax seeds in a magnetic field, the rate of chemical reactions, ion transport, membrane permeability, seed water absorption and oxygen concentration in the cells increase, which contributes to the improvement of seed sowing qualities. It is established that the change of sowing qualities of flax seeds during their treatment in a magnetic field depends on the square of magnetic induction, the gradient of the magnetic field and the movement velocity of seeds. With a change in magnetic induction from 0 to 0.065 T germination energy and germination of flax seeds increase, and with a further increase in magnetic induction begin to decrease. The change in sowing qualities of flax seeds is influenced by the velocity of their movement in the magnetic field and the gradient of the magnetic field, although they are less significant factors than magnetic induction. The best results were at lower velocity values and a larger magnetic field gradient. The most effective mode of pre-sowing treatment of flax seeds in a magnetic field is a magnetic induction of 0.065 T with four-fold re-magnetization, a magnetic field gradient of 0.57 T/m and a velocity of 0.4 m/s. With this mode of pre-sowing treatment of flax seeds in a magnetic field, the energy of seed germination increased by 30 % compared to the control, and germination - by 26 %.
