Effects of low-level microwave radiation on germination and growth rate in corn seeds

Experiments were conducted to investigate the effects of microwave radiation on germination and growth rate in corn seeds. Specimens were irradiated in an anechoic chamber, for 22 to 24 h, at CW power density levels from 10 mW/cm
²
to 30 mW/cm
²
. The radiation frequency was 9 GHz. Marked inhibition of seed germination was observed in radiated specimens, probably as a result of water loss.
