title: [Effects of magnetized soil on physiological and biochemical indexes of Brassica napus seedlings].
abstract: Nitrate reductase, peroxidase, water-soluble sugars, root vitality and total biomass of Brassica napus seedlings were investigated with soil after magnetization treatment. The results showed that nitrate reductase activity was increased by 10.76% after 200 mT treatment. The contents of water-soluble sugars were increased by 11.05% and root vitality by 26.40% for 300 and 100 mT treatments, respectively. Total biomass also showed a trend of increase as the magnetization increased. The highest biomass of the above-ground parts was achieved at 300 mT, which was 13.28% higher than that of control. In addition, total biomass of below-ground parts was the highest at 200 mT, which was 13.17% higher than that of control, and the ratio of below-ground to above-ground parts decreased by 10.00%, suggesting that the overall environmental quality of the soil was improved significantly.
