Table 2.
The effect of different NiCl2 external concentrations on non-thiol protein (NPT) and glutathione (GSH) content of M. crystallinum and B. juncea. According to ANOVA, LSD 0.05 test and considering each species alone and for the same parameter at the same column, means (n = 6 per treatment ± SE) with at least one same letter are not significantly different.
