摘要

This experimental study was dedicated to the possible oxidative stress induced by magnetic fluid accumulation in the living tissues. The aqueous magnetic fluid was prepared by dispersing iron oxide particles coated with perchloric acid in water, characterized by physical diameter average value of 10.55 nm as revealed by electron microscopy and 18.3 kA/m value for saturation magnetization. Electromagnetic exposure was accomplished during the seeds germination, within transverse electromagnetic cell at 20 mW power level and 300 kHz frequency for 30 minutes while diluted magnetic fluid was supplied both during germination and plant development. The biochemical investigations i.e. the assay of photo-assimilatory pigments and nucleic acids contents, after 12 days of plants growth were performed. Chlorophylls ratio was diminished up to 30% while plant lengths were shorter with about 40% in the samples exposed to electromagnetic field; however nucleic acid biosynthesis seems to be remarkably stimulated following the electromagnetic exposure.
