Abstract: The results of the experiment were as follows: 1. The Cd, Cu,Zn,Mn contents in the embryo of Cd-contaminated rice were higher but Fe content was lower than in the endosperm. 2. In the case of contaminated rice from amended soils, the Cd,Zn, Cu, Fe contents in the endosperm were lower than the control; the Cd,Mn contents in the embryo were lower than the control, Cu in keeping with the control, Zn and Fe higher than the control. 3. The Cd, Cu, Zn, Fe. Mn contents in the endosperm and Cd,Cu,Zn,Mn contents in the embryo of rice from meadow-brown earth were higher than that from alkaline soil, but Fe content in the embryo was in reverse. 4. The contents of soluble Cd,Zn,Fe,Mn in the endosperm of rice from amended soils were lower than the control, but soluble Cu was in keeping with the control; the soluble Cd, Cu, Zn, Fe in the endosperm of rice from meadow-brown earth were higher than those from the alkaline soil, but Mn was an exception.
