Response of Pinus sylvestris L. needles to em fields

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 SO-60-year-old pine trees in four locations near the Skrunda RLS: A - no EMF exposure, B - low EMF exposure, C and D - high EMF exposure. The chloroplasts of mesophyll of second-year needles are ultrastructurally characterised by dense stroma, a compact granal membrane system and variable amounts of starch granulesa nd plastoglobules.
