Dynamics of indole alkaloids in wheat varieties with various resistance to wheat aphid Sitobion avenae

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 hig...

Description
Summary: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.
