ON THE IMPACT OF EXPOSING MAIZE SEEDS TO A LOW FREQUENCY FIELD ON BIOLOGICAL FEATURES AND ON ASSIMILATING PIGMENT SYNTHESIS PUBLISHED

Florin IMBREA
Magnetic field, particularly low-frequency magnetic field (LMF), induces in the biological tissues, currents that result in biological effects. They claim that biological effects induced by electromagnetic fields are adaptive or compensatory effects and that the body should adjust to this environmental factor. This paper presents the effect produced by pre-germination exposure of maize seeds to a magnetic field produced by low-frequency electromagnetic waves on the biological features and on the synthesis of assimilation pigments. Trials were carried out within the Laboratory for the testing of seed quality and of seeding material of the Department of Agricultural Technology of the Banat University of Agricultural Science and Veterinary Medicine in Timisoara (Romania). The trial aimed at assessing the effect of LMF on germinating energy, germinating ability, root length, fresh root volume, length of aerial part, fresh aerial volume, as well as a chlorophyll content, b chlorophyll content, carotenoids, lipids, proteins, and fibbers measured in maize leaves 30 days after treatment. The plant pigments were determined with the spectrophotometer method, in accordance with the guidelines for analytical validation of the FDA, EMEA, FAO/WHO and the Laboratory Standard Operating Procedures “Benchmarking for design and development of innovative biotechnology, sustainable and strategic selection of genetic resources rich in bioactive compounds of plant origin” of the Department of Exact Sciences of the B.U.A.S.V.M. in Timisoara. The study showed significant differences from the point of view of the parameters analysed compared to the control that was not exposed to the magnetic field produced by low-frequency electromagnetic radiations.
