Bio molecular characterization of impact of weak electric field on the plant system

Because of the important role of plants on earth environment and life, the study of the factors affecting the growth, conservation and use of plants is essential. The emerging activities of bio molecules to enhance the plant growth under electric control have already been reported. The factors like temperature, soil conditions, atmosphere etc are common to affect the plant systems. The effect of varying as well as static electromagnetic field on seed germination and growth of plants has been found significant. On the other hand the effect of external electric field on the seed quality and sprout growing was studied and its impact was reported. The present study deals with the effect of weak electric field on plant systems like Gram, Maize and wheat which are agriculturally important in India. The seeds of the above mentioned plants were pre soaked for 24 hours in normal water and the external field producing currents of 20 mA was passed in the seeds of Gram, Maize and wheat already kept in conducting incubator for 2, 4 and 6 hours. The germination rate and morphological growth in treated condition have been observed for thirty days in comparison to control condition. The pattern of starch and reducing sugars contents in the samples has been examined and attempts have been made to find the path way of the impact of electric field by the study of the protein and DNA profiling of the samples under investigation.
