Effect of static electric fields in root cells of Vicia faba (Fabaceae).
Serial electron microscopic sections were prepared from half-ripened meristematic root cells of Vicia faba (Fabaceae) which had been exposed gradually to 700, 1000, 2500, 3500, and 5000 V/m static electric fields during seven days with and without Zn and Cd electrodes. At the end of five weeks, wall loosenings and very small nuclei were observed in those root cells which were exposed to static electric currents from the lower side of the medium without electrodes, while abnormalities in cell formation, e.g., two cells with one nucleus, and GER occurrence were present in an electrolytic (Cd upward and Zn downward) medium. The cells exposed to a static current from the upper side of the medium had small nuclei and abnormal cell divisions in the electrolyte, but in a non-electrolyte very large nuclei and thicker cell walls were observed, the cytoplasm was dense with GER, pinocytosis was seen filled with mitochondria, and protoplast formation with big nuclei was seen in exocytosis.
