Abstract

It was hypothesized that electromagnetic field (EMF) pretreatment of white mustard (Sinapis alba L.) seeds could increase the accumulation of non-essential, pollutant heavy metals such as cadmium (Cd) in shoots. Seeds of white mustard were treated with either 60 or 120 mT of alternating EMF (50 Hz) for 1 minute and then grown in a Petri dish in the presence of Cd, in comparison to the control (seeds grown without EMF pretreatment). Biomass production and content of calcium (Ca) and Cd in seedling shoots were measured. The Cd content in shoots from the EMF-treated seeds was higher in both variants than in the control (by 73% and 78%, respectively; p < 0.05). In plants treated with 60 mT, the Ca content was slightly, but significantly, lower (3%) than in the control. EMF stimulation did not affect the biomass production. The results have shown potential benefits of this physical seed pretreatment method in the context of cadmium phytoextraction, but more research is needed.
