In the context of seed technology, the use of magneto-priming, as a method for increasing
plant production, offers advantages in comparison to conventional treatments with chemical substances.
Magneto-priming is a cheap, non-invasive technique, based on the application of magnetic
fields (MF) and described as eco-friendly, with proved beneficial effects on seed germination
and subsequent plant biomass yield. In this study, seeds of flax (Linum usitatissimum), placed on
moist filter-paper, were treated with 100 mT MF strength, with exposure time of 0, 24, 48, 72, 96
and 120 h and kept in dark under laboratory conditions. Seeds that were not exposed to magnetic
field were used as controls. Efficacy of MF on seed germination and seedlings height, shoot and
root length and biomass was evaluated. The MF promoted seed germination rate by 10%-40 %,
depending of treatments, compared to control. The growth parameters were better in seedlings
exposed to all magnetic treatments, with an increase of up to 60% over the control. MF treatment
of 24 h had a 50% better effect than 120 h MF treatment. In addition, the best biomass yield of
acclimated plants was achieved after the shortest magnetic exposure treatment. This study suggests
a positive effect of stable MF on flax seed germination and subsequent growth of seedlings.
Therefore, magnetic field may be useful in organic agriculture in replacing the usage of plant
growth regulators.
