Sažetak
The effects of exposure to radiofrequency fields on germination and seedlings growth were investigated in lettuce (Lactuca sativa L.), tomato (Lycopersicum esculentum L.) and onion (Allium cepa L.). Seeds were exposed to continuous EMF (23 V m-1) at 400 and 900 MHz for 2 and 4 h as well as to modulated field (80% AM 1 kHz sinus) for 2 h in GTEM-cell. At 400 MHz, inhibition of lettuce germination was noticed after 2 h of exposure to continuous RF-EMF while the growth of lettuce and tomato was decreased after 4 and 2 h of exposure, respectively. Contrary, the growth of onion was increased after 2 h of exposure to continuous RF-EMF. At 900 MHz, increased germination of tomato was observed after exposure to modulated field. At this frequency, the growth of lettuce increased after 4 h of exposure to continuous RF-EMF while the growth of onion increased also after exposure to modulated field. On the other hand, the growth of tomato decreased after 2 and 4 h of exposure to continuous RF-EMF. Results indicate that seedlings growth was more sensitive to RF-EMF exposure than germination and that the effects depended on field and exposure characteristics as well as plant species.
