Aboveground biomass of species grown as a monoculture or in a mixture with a second species (a) and the relative interaction index (RII) of growing with a neighbor (b). A positive RII indicates that plants have greater biomass in mixtures than as a monoculture, and vice versa. HS = H. spontaneum, T. D = T. dicoccum subsp. dicoccoides, TM = T. monococcum subsp. aegilopoides, AVS = A. sterilis, AS = A. speltoides, BB = B. brachystachys, EO = E. orientale, SV = S. vavilovii, TCM = T. caput‐medusae. For mixtures, the species written first in the code shows the species plotted. For example, “HS.AS” are the data for H. spontaneum when grown with A. speltoides. In (a), small colored points show replicates and large black circles are the treatment means
