摘要：

The postulate that 60-Hz electric field-induced bioeffect severity is proportional to induced transmembrane potential [ {Mathematical expression}] magnitude was tested and supported using a plant root model cell system. Statistically significant correlations were obtained upon regression of the relative rates of exposed Vicia faba and Zea mays root segment growth on the average {Mathematical expression} (calculated) arising in those segments under specified 60 Hz field exposure conditions. The {Mathematical expression} associated with the apparent threshold for growth inhibition was similar in Zea and Vicia roots (2.5 vs 2.4 mV, respectively). At {Mathematical expression} greater than this threshold, Zea root growth declined by about 9% per mV, and Vicia root growth by about 19% per mV induced potential. © 1990 Springer-Verlag.
