Germination indices: total germination; CVG, GRI and MGT determined for quinoa seeds after 7 days of germination in the presence of NaCl, CaCl2, KCl, MgCl2 and SW at different concentrations. Data are expressed as percentage in respect to control. Data are the means of five replicates. ***P < 0.001; **P < 0.01: *P < 0.05.
