To share the absorbed nitrogen with host plant would be one of strategy for survival of root parasites. Translocation of Nnitrate or Nammonium 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 NH in the shoot to in the whole - infected plant was lower than in no-infected plant, indicating that easily compared with NO.
