Physiological parameter changes in response to LN in Socaire and Faro. Radar chart shows relative changes in leaf and root proteins, chlorophylls (Chl a and b and Chl a/b ratio), chlorophyll fluorescence parameters Fv/Fm (maximal efficiency of PSII), NPQ (non-photochemical quenching) and qL (the proportion QA in the reduced state), protein and NR and GS enzymatic activities and their respective gene expressions (CqNR and CqGLN) in two landraces of quinoa. Changes were calculated as the ratio of LN level (0.5 mM of NO3) to HN level (20 mM NO3). Values are means (n = 5). Socaire ratio changes were denoted in pink color and Faro in green. Symbols ¤, * and X indicate significant differences among landraces (L), nitrogen treatments (N) and interaction among both factors (L x N) using two-way ANOVA (Fisher LSD test; P < 0.05). Data for statistical analysis are shown in Suppl. Table S2
