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 300mT, which was 13.28% higher than that of control. In addition, total biomass of below ground parts was the highest at 200mT, 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.
