Abstract__ Background Weak magnetic and electromagnetic fields can influence physiological processes in animals plants and microorganisms but the underlying way of perception is poorly understood. The ion cyclotron resonance is one of the discussed mechanisms predicting biological effects for definite frequencies and intensities of electromagnetic fields possibly by affecting the physiological availability of small ions. Above all an influence on Calcium which is crucial for many life processes is in the focus of interest. We show that in Arabidopsis thaliana changes in Ca2 -concentrations can be induced by combinations of magnetic and electromagnetic fields that match Ca2 -ion cyclotron resonance conditions.
