Sensitivity of Some Plant Material to Magnetic Fields

Biological effects of static magnetic fields: a selective review with emphasis on risk assessment

“…The repression effect seen by Dunlop and Schmidt (1969) contrasts with the results of Mericle et al (1964), Mho looked at the growth of barley seeds under the influence of magnetic fields. They found initial increases of growth in both shoots and roots.…”

“…They found initial increases of growth in both shoots and roots. The absolute magnitude was less than that experienced by Dunlop and Schmidt (1969), and the difference from controls decreased with time ( Fig. 8).…”

Alternating magnetic field effects on yield and plant nutrient element composition of strawberry (Fragaria x ananassa cv. camarosa)

“…Increasing MF strength from control to 0.384 T increased contents of N, K, Ca, Mg, Cu, Fe, Mn, Na and Zn, but reduced P and S content. constant environmental condition encountered biologically (Dunlop & Schmidt, 1969), and the physical mechanism of their effects is now becoming understood. Electric or magnetic treatments are assumed to enhance seed vigour by influencing the biochemical processes that involve free radicals, and by stimulating the activity of proteins and enzymes (Jia-Ming, 1988;Kurinobu & Okazaki, 1995;Morar et al, 1999).…”

Effects of Magnetic Water Irrigation on the Growth, N Uptake and Antioxidant Enzyme Activities of Cotton Seedlings

“…Furthermore, magnetic-treated water significantly contributed to nutrient uptake, assimilation and mobilization, thereby improving plant productivity [19]. On the other hand, magnetic treatment may not influence or even detrimentally impact crop growth or plant physiological characteristics [20]. Hirano et al [21] found that 70 mT magnetic treatments clearly constrained the growth and photosynthesis of Spirulina platensis.…”
