%X UV spectrometry measurement on the indole alkaloids (IA) contents of seven wheat varieties (KOK1679, My295, Li, Han4564 and Yanda1817, resistant to S. avenae; Shaanximazha and Lovrin10, susceptible to S. avenae) showed that during tillering and stem elongation stages, KOK1679, My295 and Li had a higher IA content (> 0.5 mg.g-1 FW); and during heading and anthesis stages, the penultimate leaves of all five resistant varieties contained higher IA (> 0.5 mg.g-1 FW). The IA content was lower in the flat leaves of both resistant and susceptible varieties, but was significantly higher in the ears of resistant varieties (up to 0.645 mg.g-1 FW in KOK1679) than in those of susceptible ones. It was showed that the IA content in wheat's ear played an important role in the resistance to S. avenae.
