FIGURE 5

Leaf and root activity of peroxidase (A) and esterase (B) in maize plants treated for 48 h with two dosages (0.1 and 1 mL L–1) of the protein hydrolysates from either chickpea (Cicer arietinum L., CA) or Spirulina platensis (SP). Different letters above bars indicate significant differences (p < 0.05) among leaves (bold) and roots (unbolded). Data are the means of 5 values each from three independent experiments (±SD).
