| Abstract: | The wheat seedlings were treated with different concentrations of rare earth of nitrate R(NO_3)_3] and rare earth of chloride RCl_3]. It shows that the dry matter accumulation and roots, stems growth of wheat seedling were increased in low Concentrations, There is an increasing tends in nitrate reductase activity and nitrat uptake in low and high concentrations, but the inerea sing of nitrate reductase activity and nitrate uptake was not in agreement. |

| Keywords: | Rare earth Wheat Nitrate reductase activity |
