Effect of presowing magnetic treatment on properties of pea. med./bio.

Published in: International Agrophysics 2012; 26 (1): 23-31

Aim of study (acc. to author)

To investigate the effects of exposure to magnetic fields on pea seedling growth and chlorophyll contents.

Background/further details

Exposure was applied with three different magnetic flux densities (60 mT, 120 mT, and 180 mT) and three different durations (5 min, 10 min, and 15 min). Non-exposed seeds were used as control group.

Setup cylindrical coils: 4,000 turns of 0.42 mm copper wire; each coil was wound 10 cm apart on an iron bar (40 cm x 3.5 cm); iron bars were placed one above the other, their ends held by metallic supports; petri dish was placed in the air gap between the two bars
Sham exposure A sham exposure was conducted.

Main outcome of study (acc. to author)

The exposure to a magnetic field significantly increased the seedling growth compared to the controls. Exposed seedlings did not show a significantly increase in chlorophyll contents. Among the various combinations of magnetic flux density and duration, 120 mT for 15 min and 180 mT for 10 min exposure yielded superior results.
The authors concluded that the exposure to a magnetic field could be used to enhance the growth in peas.
