Abstract: Falling into a high voltage electrostatic field, rice, rape and sesame seeds displace in the direction of the field under the action of the field. The separating distances of the seeds of basically the same quality and at the same hight vary greatly, and have obvious relations with an improvement on the seeds' germinative percentage and force. Experimental results show that the mechanism of the seeds' improved viability intensity lies in the obvious improvement of their pancreatic amy-lase activation, proteinase activation and electric conductance.
