Abstract

Background and objectives: Electric, magnetic and electromagnetic fields can act as stress factors with different effects on biological systems. Due to the nutritional and medicinal values, and the increasing electromagnetic radiations, the present study was performed to investigate the effects of the electromagnetic field on the developmental stages and cytotoxic properties of okra.
Methods: Both dry and wet seeds were exposed to electromagnetic field with the intensities of 2 and 4 mT for 60 minutes. MTT assay was applied to evaluate the potential cytotoxic effects of okra extract on MCF-7 cell line. The anatomical structure of leaves in both treated and untreated (control) plants were examined.
Results: The results showed that a field intensity of 4 mT increased the speed of germination of wet treated seeds and the stem length of dry treated seeds. MTT assay revealed no cytotoxicity of the aqueous extracts of okra pods up to the concentration of 100 μg/mL from either the treated or the control plants towards the MCF-7 cell line.
Conclusion: The results suggest that the electromagnetic fields would be able to increase the speed of germination without effects on percentage of germination.
