Abstrakt		Direct magnetic-field (MF) effects and effects mediated through magnetically treated water by a weak and extremely-low-frequency (ELF) MF of 50 Hz,105 microT on the growth of spruce seedlings were studied. The seeds were watered simultaneously with distilled and deionized water (DD), with DD + 0.25, 0.5, or 5 mM Ca2+, and with tap water (1.7 mM Ca2+). The results showed the inhibitory effect of the MF on total germination on day 5 of the experiment. The direct treatment of seeds yielded a significant inhibitory effect at 0.5 mM Ca2+, while indirect treatment showed a significant inhibitory effect at 0.25 mM Ca2+. On the other hand, the time distribution of germination showed a heterogeneous time response, with the most frequently significant effects at 0.25 mM Ca2+. The comparison between direct and indirect treatment of the seeds reveals some similarities as well as differences in effects. There were no effects on the length of the seedlings after 7 days of exposure.
