Revised Date: 14 May 1998

The contents of Cd and Pb in soybean seedling and the ecophysiological effect of La on the injury of Cd and Pb to the plant have been investigated. The results showed that the culture containing solutions of 500 mg/L of CdCl₃ or 1000 mg/L of Pb(Ac)₂ inhibited the growth of the soybean seedling and increased Cd or Pb content in it, and spraying one with LaCl₃ solution in concentration of 30 mg/L to the seedling could reduced their injury effect and content in the plant.
