Investigation carried out at the Department of Physics, University of Agriculture in Lublin consisted in the application of an alternating magnetic field (50 Hz, harmonic vibration) for the biostimulation of wheat seeds.The purpose of research was to define the effect of the magnetic biostimulation on the germination of seeds. The wheat seeds were subjected to 18 different magnetic ex- posure doses. For the next investigation two magnetic exposure doses were selected. On the basis of the research, it can be said that germination capacity of wheat seeds de- pends on the magnetic exposure dose. The speed of germi- nation of the treated seeds was higher than in the case of untreated ones. The seeds with the highest moisture content and subjected to a higher magnetic exposure dose had the highest speed of germination. Maximum speed of germi- nation for all the studied combinations was observed 35 h after magnetic biostimulation.
