Maximum nitrate reductase (NRmax) and real nitrate reductase (NRreal) and nitrate reductase (NR) activation state in leaves of Zea mays L. amylacea after 20 days of treatment with NaCl (0 mM; 100 mM; 430 mM) and H3BO3 (B0, control; B20, 20 mg kg−1; B40, 40 mg kg−1). Values represent the mean ± SE of three independent experiments. Bars with the same letter are not significantly different according to LSD at a level of p < 0.05. On the right side: relationships between NR and stomatal conductance (gs) (right top) and NR and nitrate content in leaves (right bottom) of the amylacea ecotype of Zea mays L. amylacea.
