Study on Effect of Transient Electromagnetic Field on Germination of Seed Plants

－The Effect of the Number of Applications of Transient-electromagnetic-field on Plants－

Abstract

This paper describes an effect of transient electromagnetic fields on the germination of seed plants. In our experiment, transient electromagnetic fields by spark discharges were applied to seeds of asparagus, parsley, carrot, lettuce and Komatsuna. In this experiment, the pulse widths of discharge current (800 A) were set to 3 µs, and the number of applications were set to 5 times, 10 times, 20 times and 30 times, respectively. As a result, we found that 1) the germination rate tended to increase within a certain range of the number of applications, 2) the germination rate decreased when the number of applications exceeded a certain number.
