Effect of Magnesium(Mg) on Root Activity, Chlorophyll Content and Membrane Permeability of Soybean

In these experiments, three varieties of soybean were employed as the main material, with the method of water cultural and soil cultural experiments to study the effect of Mg on root activity, chlorophyll content and membrane permeability of three cultivars of soybean. The results showed that the control plants under low Mg exhibited a significant decrease in root activity, chlorophyll content but an obvious increase in membrane permeability. Application of proper Mg raised effectively the root activity and the contents of chlorophyll, while the membrane permeability decreased obviously. ZhechunNO.3 soybean is most sensitive to Mg.
