To share the absorbed nitrogen with host plant would be one of strategy for survival of root parasites. Translocation of $^{13}$ N $^{-}$ nitrate or $^{13}$ N $^{-}$ ammonium in the root system of red clover infected by broomrapes ( Sm.) was examined by a positron emitting tracer imaging system (PETIS). PETIS images indicated that the distribution ration of $^{13}$ NH $_{4}$ $^{+}$ in the shoot to in the whole - infected plant was lower than in no-infected plant, indicating that easily compared with $^{13}$ NO $_{3}$ $^{-}$ .
