The effects of short exposure of seeds of lupine (Lupinus L.) and lucerne (Medicago sativa L.) to a lowfrequency magnetic field (f=50 Hz, B= 30 mT), laser-light radiation (λ = 632.8 nm), and their combination on germination parameters and the content of photosynthetic pigments were examined. Independent studies were done on Petri dishes and in pots. As shown by data, short-term pre-sowing treatment with the physical factors mentioned above in most cases neither influences the germination parameters of the examined plants (no statistical differences between most of the samples) nor produces any negative effects.
Generally, an increase in the content of photosynthetic pigments was observed for lupine while no statistically relevant effect of pre-sowing stimulation on lucerne was observed in the laboratory experiment. The pot experiment on lucerne showed statistically relevant differences.
Comparing our data and the results obtained by other groups, we conclude that a short-term stimulation of selected Fabaceae with electromagnetic factors does not significantly influence the germination parameters or the content of their photosynthetic pigments. No statistical differences were found between coarse-grained and small-seed plants.
