  • P values indicated are from tests of significance of the genotype × treatment interaction term in ANOVA analyses across pairs of environments and indicate whether cross-environment correlations are significantly different from 1. Most comparisons were significantly different than 0 as indicated by a significant genotype effect in ANOVA analyses across pairs of environments, except Narea across WL/CL and WL/CS was not significantly different from 0. Δ13C, carbon isotope discrimination; Narea, nitrogen concentration on a leaf area basis; LMA, leaf mass per area. *P < 0.05; **P < 0.01; ***P < 0.001; ****P < 0.0001.
