Abstract

The present study explored the effect of the irradiation of strawberry (Fragaria Ã— ananassa) seeds by a lowfrequency magnetic field with the help of a developed device for magnetic-pulse processing of plants.The experiment was repeated three times; 24 batches of 30 seeds per batch were involved and one batch of 100 seeds was taken as a control.The induction of the pulsed magnetic field in the processing zone was 4, 5, 6 mT, regulated by moving the working body of the inductor (magnetic coil).The experiment showed that low-frequency pulsed magnetic had a positive effect on the germination energy and the germination of strawberry seeds. Statistical processing of the obtained experimental results was carried out by means of mathematical modeling by orthogonal planning of experiments.On the 18th day of registration, the germination energy of strawberry seeds treated with a low-frequency pulsed magnetic field exceeded the control indicators by 21%. Based on the calculated coefficients of the mathematical model, the response function and equation of the mathematical model were found.The graphical interpretation of the function of three variables and the chart of lines of equal level (contours) were constructed.The values of the extremum of the response function and the corresponding values of the factors in the coded and natural form were obtained.The analysis of these factorial experiments showed that the most effective parameter of irradiation for increasing germination and seed germination energy is irradiation with a frequency of 15.325 Hz, a duty ratio of 16.145 and magnetic induction in the irradiation zone of 5.05 MT.
