Abstract: In the present study, the effects of two selenium (Se) application methods and different Se concentrations on the dry weight and element contents of rapes were investigated. It was shown that 2 selenium application methods had similar influences on rape. The rape biomass was increased by the lower Se levels (0.1 mg·kg-1 in soil or 0.1 mg·L-1 foliar application), yet was decreased by the higher Se levels (1.0 mg·kg-1 in soil or 0.5 mg·L-1 foliar application). External Se application increased the contents of N, P, K, Ca, Mg, Mn in roots, stems, and leaves, as well as Fe in roots, Cu in leaves and Zn in stems and root. External Se application enhanced the translocation of N, P, K, Mg, Fe, Cu, Zn from stems to leaves, while reduced the translocation of P, K, Mg, Fe, Zn from roots to stems. Se application reduced the translocation of Ca from roots to stems at the lower levels, whereas the translocation of Ca was enhanced from stems to leaves at the higher levels.
