Seeds of the Caragana intermedia and Artemisia schrenk songarica in Maowusu sandland were treated with different strongths of electric current. Under controlled conditions the effects of the exposure to electric fields on the drought resistance of the seeds in the germinating stage were tested. The results show that electric field treatment can reduce the negative impacts of drought. The different electric field strengths have different effects on the drought stress adaptability of the seeds in the germinating stage and on plant biomass. It is concluded that electric field treatment can increase seed germinating potential, germination rate, plant biomass and both wet and dry weights. All these changes are favorable for reducing drought damage and improving plant adaptation.
