Germination and Early Growth of Sunflowers in Weak ELF Electromagnetic Fields

Abstract

Sunflowers (Helianthus annuus) were raised in a weak ELF electromagnetic field under controlled laboratory conditions and in a greenhouse. The field levels were 10 or 1 volt/meter rms electric field and 1 gauss rms magnetic field at 75 Hz. The observations and statistical analysis of these experiments is documented in the report. It has been concluded that under field conditions the small, but probably real, effects of a weak electromagnetic field would be indistinct from, and interact with, those brought about by any other micro-environmental factors.
