The mean values have been determined in relation to the appropriate control. For all control samples B = 0.
G - germination capacity, HSS - mean water content, WSS - wet mass od single seedling, GREL- relative germination, HREL SS - relative water content, WREL SS - Relative mass of a single seedling. Statistical significance occurred only for the combined effect of Fe-NPs and the magnetic field and is marked with C.
