Effect of D.C. Electric Field on Growth of a Plant
Yuji MURAMOTO,*,1 and Noriyuki SHIMIZU*(Received January 8, 2008; Accepted March 26, 2008)

In this study we investigate the effect of D.C. electric field on the growth of a plant. The specimens are the whiteradish sprouts. The statistical test shows that the D.C. electric field accelerates the rate of growth of the white radishsprouts. It is also revealed that the effect of D.C. field on the growth is influence by the time when the D.C. electricfield is applied in a day.
