Table 4.
At the mixture scale, effects of patch size, species combination (Elymus nutans + Festuca sinensis, Elymus nutans + Poa pratensis, Elymus nutans + Vicia unijuga, Festuca sinensis + Poa pratensis, Festuca sinensis + Vicia unijuga, and Poa pratensis + Vicia unijuga), and their interaction in GLM on the seed germination percentage, plant height, and plant biomass. F-values, P-values, and degrees of freedom (df) are given, with significant results (P < .05) in bold.
