AB  - Root parasitic weeds broomrapes (Phelipanche and Orobanche spp.) cause devastating damages to agricultural production all over the world. The seeds of broomrapes germinate when they are exposed to germination stimulants, mainly strigolactones (SLs), released from roots of any plant species, while broomrapes parasitize only dicot plants. Therefore, monocots can be trap crops for broomrapes, as they induce seed germination but are not parasitized. In this study, we examined two European and one Japanese cultivars of barley for their potentials as trap crops for broomrapes and found that the European cultivars, Sebastian and Golden promise, are good potential trap crops as they produce more SLs and exhibit higher mycorrhizal colonization rates as compared to the Japanese cultivar Shunrai.Competing Interest StatementThe authors have declared no competing interest.
