Study on physical and chemical properties of flying coal ashes and the releasing patterns of silicon
粉煤灰理化性质与硅素释放规律的研究

There exists a redox system at the surface of the roots and shoots in winter wheat. The oxidation rate of NADH of the shoots is the highest at the fastest growth stage under normal water supply. The growth of roots and shoots is significantly inhibited under osmotic stress. In plasma membrane of roots and shoots, the force of reducing K3Fe(CN)6 is increased under stress, and that of shoots is more stimulated, however, the oxidation rate of NADH is higher than that of control at the stress beginnings and final stages, and no significant differences is observed at other periods.
