Hairy vetch (Vicia villosa Roth.), which produces large amounts of cyanamid, is widely utilized as a winter cover crop in the United States and Japan. The use of trap crops which induce 'suicidal germination' is one of the control methods for root parasitic weeds. Among germination stimulants for root parasitic weeds, dihydrosorgoleone, sesquiterpene lactones, and strigolactones (SLs), SLs are known to be most widely distributed in land plants. In this study, identification of SLs produced by hairy vetch plants was conducted. LC-MS/MS (MRM) analysis revealed that hairy vetch produces fabacyl acetate, ent-2'-epiorobanchyl acetate and 5-deoxystrigol. Time-course of strigolactone production will also be presented.
