The article presents the results of experimental studies on increasing the growth rates of three varieties of soft wheat Triticum aestivum (L.) after pretreatment of seeds with a pulsed magnetic field (PMF). The pulse effect shape is a damped sinusoid, the effect intensity is induction B = (0.53÷5.21) T, the effect duration is microseconds, the number of pulses n = 3 with an interval between them Δτ= 3 s. Previously, the magnetic field effect with such parameters in crop production has not been studied. The greatest stimulating effect of the magnetic field is observed on wheat sprouts of the Tulaykovskaya Nadezhda variety: a statistically significant increase in the length of the sprouts by 3.4-3.6 times compared with the control. An assumption has been made about the mechanism of such a PMF effect on growth indicators: stimulation of oxidative stress in plants, increase in the concentration of mineral elements in the cell due to changes in membrane permeability. The ways of further research are determined.
