Symbiotic fungi from a wild grass () increase the growth, grain yield and quality of tritordeum under field conditions.

Plants function in symbiosis with numerous microorganisms, which might contribute to their adaptation and performance. In this study, we tested whether fungal strains in symbiotic interaction with roots of , a wild grass adapted to nutrient-poor soils in semiarid habitats, could improve the field performance of the agricultural cereal tritordeum ( × ). Seedlings of tritordeum were inoculated with 12 different fungal strains isolated from roots of that were first proved to promote the growth of tritordeum plants under greenhouse conditions.
