In the present research seeds of red cabbage (Brassica oleracea L. cv. saccata) were genninated in sterile conditions and then grown in plastic pots for I month. Unique plants in their vegetative growth phase were selected and divided to the control and treatment groups, randomly. The treatment plant groups were exposed to a 30 mT static magnetic field for 10 days, each 5 hours and then both the treated plants and the control ones were harvested, frozen with liquid N2, and kept at -80°cuntil used for biochemical measurements. Exposure of seeds of red cabbage to the aforesaid static magnetic field during germination also induced further growth of the plants. Compared with the non-treated plants, increase in the contents of anthocyanins, and wall-bound phenolic compounds of shoot were observed in those plants which were treated with static magnetic field. The later also had reduced activity of PAL and reduced amounts of lignin and total sugar contents in both roots and shoots, compared with those of the control plants.
