A device for transporting and storage of fish gametes, developing eggs, and newly hatched fry in a constant, adjustable (3-9 mT) magnetic field was constructed. The device has a relatively large, thermally insulated, biological material storage compartment, exposed to highly uniform (± 2.5%) magnetic field.
Review of papers dealing with the influence of magnetic fields on seeds and plants grown from them, was presented. The influence of geomagnetic field and different weather phenomena were discussed. The effects of static magnetic field of different magnetic flux density and low frequency alternative magnetic fields were also presented. Finally, the role of high frequency electromagnetic fields and their application in agricultural practice were described.
The influence of 16 Hz and 50 Hz frequent magnetic field on the germination of seed of different agricultural crops (spring wheat, soybean and maize) under the stress condition (temperature 5°C or 10°C) was examined. The acceleration of germination and decrease of Pieper'si coefficient of seeds treated with frequent magnetic fiels in comparison with untreated seeds was found.
