The effect of the high electrostatic field(HVEF) on rice seeds was studied.The seeds included the dry seeds and the wet seeds which were sopped for 24 hours at 30℃ before the HVEF treatment.The results show that the seeds finished imbibition and germinated after being sopped for 24 hours.The germination velocity,vigor index of wet seeds and the dry weight of seedings are significantly increased after appropriate treatments.But HVEF slightly affect the seed vigor of the dry seeds,instead,the vigor of dry seeds decrease after treatment.The moisture content of the seeds highly affect the biological effects of HVEF on rice seeds.
