要約(英語): This paper describes an analysis of the effects of transient electromagnetic fields on the growth of a plant. In our experiment, a single transient electromagnetic field, which was radiated from a discharge electrode (2 cm) of a discharge generator, was periodically applied to seeds and seedlings of broccoli (Brassica oleracea var italica) for three weeks. The pulse application cycles were set to 1 day and 3 days with charging voltages of 10 kV and 15 kV. In a growth environment, temperature and humidity were set to 25 (±3) ℃ and 50 (±10) %, respectively. Light photon at the top of leaf was set to 110 (±30) µmol/m2s and illuminating lamp lighted for 24 hours. Then, we measured the length and chlorophyll density of leaves of the growing plants in each condition. Also, based on measured current that flowed through the discharge electrode, we evaluated the radiated electromagnetic energy level by using an electric dipole model. As a result, we found that samples, which had been applied 10kV/3days and 15kV/3days, became greater than the others by around 30%. Also, the chlorophyll density of 10kV/3days and 15kV/3days became higher than the others.
