Duchovskis, A. StaðelisSummaryVegetation experiment was carried out in the greenhouse of the Laboratory ofPlant Physiology at the Lithuanian Institute of Horticulture. The influence of the constant(1000 A m -1 , 1800 A m -1 ) and variable (800 A m -1 , 200 A m -1 ) electromagnetic fields onthe growth of fat Hen and germination power and viability of seeds was investigated. Itwas established that various electromagnetic fields stimulated the growth of fat Hen.The growth of the younger plants, which apical meristems were not differentiated, werestimulated even more. Seed germination power and viability were determined by thedirection of vector of electromagnetic field power. When the direction of vector ofelectromagnetic field power coincided with the direction of plant growth seedgermination power and viability were several times bigger than in the case oppositedirection action. When the power of the variable electromagnetic field increased seedgermination power and viability increased also.Key words: Chenopodium album L., growth, electromagnetic field, seedsgermination power, seeds viability.198
