Abstract: It is a very difficult problem on how to determine the weights between the biological indexes in comprehensive evaluation of biological information. In this paper, we apply the non-parametric generalized data envelopment analysis method to form a comprehensive evaluation method for analyzing the aging property of electric field influence on plant seeds. This method can not only give the individual information of seeds, but also overcome the difficulties of determining index weigh. Then, we analyze the aging property of influence of electric field on wheat seeds by using this method. The results show that the seedling morphological indicators of wheat seeds present oscillatory changes with the increase of electric field intensity when the scope of field strength is 0.5kV/cm~6.0kV/cm, and the significant effects gradually disappear with the extension of storage time.
