The goal of this protocol is to demonstrate the acceleration of the initial growth rate of plants by applying static magnetic fields with no external energy.

Electronic devices and high-voltage wires induce magnetic fields. A magnetic field of 1,300-2,500 Gauss (0.2 Tesla) was applied to Petri dishes containing seeds of Garden Balsam (Impatiens balsamina), Mizuna (Brassica rapa var. japonica), Komatsuna (Brassica rapa var. perviridis), and Mescluns (Lepidium sativum). We applied magnets under the culture dish. During the 4 days of application, we observed that the stem and root length increased. The group subjected to magnetic field treatment (n = 10) showed a 1.4 times faster rate of growth compared with the control group (n = 11) in a total of 8 days (p <0.0005). This rate is 20% higher than that reported in previous studies. The tubulin complex lines did not have connecting points, but connecting points occur upon the application of magnets. This shows complete difference from the control, which means abnormal arrangements. However, the exact cause remains unclear. These results of growth enhancement of applying magnets suggest that it is possible to enhance the growth rate, increase productivity, or control the speed of germination of plants by applying static magnetic fields. Also, magnetic fields can cause physiological changes in plant cells and can induce growth. Therefore, stimulation with a magnetic field can have possible effects that are similar to those of chemical fertilizers, which means that the use of fertilizers can be avoided.

Germination is the growth of a plant that results in the formation of the seedling1. Under certain conditions, seed germination begins and the embryonic tissues resume growth. It begins with hydration to the seed in order to activate enzymes for germination. Seeds can be induced to germinate in vitro (in a Petri dish or test tube)1,2.

Static magnetic fields are special forces that cause movements of molecules with ionic charges by way of the Lorentz force3,4. Lorentz force is formed when an ionized or charged object moves under a magnetic field. Every material is formed with atoms which are composed....

1. Initial Settings

  1. Agricultural Plant Species
    1. Use Garden Balsam (Impatiens balsamina), Mizuna (Brassica rapa var. japonica), Komatsuna (Brassica rapa var. perviridis), and Mescluns (Lepidium sativum) seeds.
      NOTE: Impatiens balsamina (Garden Balsam or Rose Balsam) is a species native to India; a few members are also located in Myanmar. Komatsuna (Brassica rapa var. perviridis or komatsuna) is a variant of the same spec.......

Tubulin staining showed dispersed or thinned structures in plants grown in the presence of the magnet compared to the control (Figure 2). Moreover, 7 day time-lapse studies with agricultural plants including Komatsuna (Brassica rapa var. perviridis) and Mescluns (Lepidium sativum) indicated that a magnet derived static magnetic field increases the initial growth of these plants (Figure 3).

In all conditions, magnets should be applied under the petri dish. This study examined the influence of magnetic fields on growth rate of seeds for several agricultural species, with focus on Garden Balsam as a representative of agricultural plants. For instance, tubulin staining was performed on Garden Balsam to evaluate the molecular-level changes in root and stem skeletal micro-structures suggesting influence of the magnetic field in length proliferation. Both the N and S poles of the magnet were applied in a long-ter.......
