Abstract. This study is focused on the biochemical changes induced by low level of 900 MHz frequency electromagnetic field in young plantlets (popcorn, i.e. Zea mays) provided of irradiated seeds. In this experiment, Zea mays seeds have been exposed to RF field of low power density, for different time intervals, between 0.5 and 36.0 hours. Assimilatory pigments and average nucleic acid content were assayed after 12 days of plantlets growth, by spectrophotometric methods. Certain inhibition of chlorophylls biosynthesis was noticed while stimulatory effect upon the nucleic acid biosynthesis was revealed. Plant development was stimulated by radiation, as revealed by average length compared to controls.
Key words: 900 MHz, biological effect, electromagnetic field, Zea mays, photoassimilatory pigments, nucleic acids level.
