Abstract: The function of Nd3+ with different concentrations in oilseed rape under Ca-deficiency was studied.The results indicate that the root surface-area of rape which treated with 3 μmol*L-1 Nd(NO3)3 is enlarged,and the taproot length,root dry weight and root CEC all increase as well as roots oxidizing capacity.Nd3+ can replace Ca2+ partially,and the replacement action is embodied likely through plasmolemma Ca2+-ATPase with signal transduction pathway.Nd3+ shows mainly its toxic action under high concentration(60 μmol·L-1).
