Changes in the activities of the antioxidant enzymes (superoxide dismutase (SOD) (U g⁻¹), glutathione reductase (GR) (U L⁻¹) and catalase (CAT) (g⁻¹ d. wt. equiv. h⁻¹) and two oxidative enzymes (polyphenol oxidase (PPO) and indoleacetic acid oxidase (IAAO) (g⁻¹ d. wt. equiv. h⁻¹) in fresh leaf tissue of rosemary (R. officinalis) plants at first cut as affected by foliar spray with S. platensis at 0.0, 0.1, 0.2 and 0.4%, irrigation with heavy metals (Cd as Cd nitrate; Pb as lead acetate; Cd + Pb each at 100 ppm), either alone or in combination with S. platensis at 0.1%. Statistical analysis was carried out using Duncan test. Vertical bars represent LSD at 0.05 level and different letters show significant variation at 0.05 P.
