A pre-sowing electromagnetic treatment of maize seeds was carried out. A laboratory setup was designed for measuring the resistance of maize seed germs at signal frequency 10 kHz. The setup is appropriate for use in the process of student training. The resistance values were determined for the seed germs of French maize hybrid LG 34.75, treated and untreated in an electromagnetic field. The parameter S, expressing the ratios of measured resistance values of electromagnetically treated to untreated seeds, was analyzed. The resulting values for the parameter S, after a 14-day rest of the seeds, were closest to and smaller than 1. This correlated with the time limit determined from practical experience for sowing the seeds following their electromagnetic treatment. It was established that for the seeds of the French maize hybrid LG 34.75, the parameter S values were more dispersed around the value 1 in comparison to the values obtained by other authors. This could be attributable to the genetic specifics of the examined maize hybrids.
