Influence of D.C. electric field on growth of arabidopsis thaliana (thale-cress)

This paper reports the influence of D.C. electric field on plant growth. In previous paper, we had reported that the D.C. electric field improves the growth of Raphanus sativus longipinnatus (daikon radish). We also reported that the D.C. electric field improves the seed germination rate of Arabidopsis thaliana (thale-cress). In this paper, the results for the thale-cress will be confirmed. Furthermore, we will show the new result that the D.C. electric field exerts no effect on seed germination when the electric potential of the sample is grounded by insertion of the grounded stainless steel plate into the seed bed.
