Fig. 6From: Comparative physiological and biochemical mechanisms of salt tolerance in five contrasting highland quinoa cultivarsK+ and Na+ contents and K+/Na+ ratios in leaves and roots of seedlings of five quinoa cultivars under different saline levels. Different small and capital letters indicate significant differences between the saline levels (S) within each cultivar and between cultivars (C) across different saline levels, respectively, at P < 0.05 level. Each value is the mean ± SD of three to four replicate measurements. *** P < 0.001Back to article page
