Abstract

Overview

Magnetic fields created by atmospheric conditions may impact plant growth and their responses to environmental stimuli.

Findings

  • This study focused on how a 14.3 Hz extremely low-frequency magnetic field affects the electric reactions in wheat leaves under blue light exposure.
  • The reaction observed includes depolarization followed by dual phases of hyperpolarization, enhancing the potential to levels above those in darkness.
  • Significant roles were identified for calcium ions and the calcium-dependent H+-ATPase in the plasma membrane during this reaction.
  • Influence of magnetic fields possibly occurs through the activation of H+-ATPase prompted by increased calcium influx.

Conclusion

The study provides evidence suggesting that low-frequency electromagnetic fields can modulate plant physiological reactions by influencing calcium-dependent mechanisms.
