Response of Pinus sylvestris L. needles to electromagnetic fields. Cytological and ultrastructural aspects

The effects of pulsed radio frequency electromagnetic field (RF EMF) on plant growth and development are still unclear and contradictory. The aim of this work is to study the impact of RF EMF generated from the Skrunda Radio Location Station, Latvia, on growth and development of pine trees. Pine needles and cones were collected in 1993 from the tops of 50–60-year-old pine trees in four locations near the Skrunda RLS: A — no EMF exposure, B — low...
