Flax (Linum usitatissimum) is an important food and fiber crop, due to its nutritional and nutraceutical qualities. Flax seeds have been consumed for at least 6,000 years, which makes it one of
the world’s first cultivated crops. Seed priming with living bacterial inoculum, termed biopriming,
involves the application of plant growth-promoting rhizobacteria. The present study was conducted to investigate the effect of growth-promoting rhizobacterium Bacillus amyloliquefaciens
on the growth of flax seedlings under different strengths of magnetic field. Seedlings were soaked
in bacterial suspension and bacteria were allowed to colonize. After ten minutes of soaking, the
seedlings were exposed to magnetic field of 60 and 90 mT for 24 h, in dark under laboratory conditions. Untreated seedlings were used as controls. Shoot and root length, number and length of
newly formed lateral roots and biomass production were measured after 1, 3, 5, 7 and 10 days. Results indicate that the combinations of magnetic field and plant growth-promoting bacteria gave
half- to two-fold better results than bacteria or magnetic field alone. The best result was achieved
in seedlings treated with Bacillus amyloliquefaciens and 90 mT magnetic field. This work showed a
significant impact of bio- and magneto-priming on the improvement of flax seedling growth and
biomass productivity.
