The effects of a magnetic field on the germination of plants were studied. When a 10 T magnetic field was applied, a cucumber shoot that germinated in the horizontal bore of a superconducting magnet leaned in the direction of the magnetic field center. In contrast, root grew in the direction opposite to the field center. The observed result seems to have occurred as follows: the cucumber recognized the direction of the resultant force of gravity and the magnetic force as the direction of gravity, the shoot and the root then grew along the line of the resultant force, according to their taxis. The results of analysis of the experimental data supported this idea qualitatively. These observation offer us important knowledge about the effect of magnetic fields on living bodies. They also suggest the possibility of applying magnetic fields in other areas of research.
