Activities of GST (a), GPX (b), SOD (c), and CAT (d) enzymes in rice seedlings treated with Ca under As stress. Here, Ca, As0.5, and As1 indicate 10 mM CaCl₂, 0.50 mM Na₂HAsO₄, and 1 mM Na₂HAsO₄, respectively. Means (±SD) were calculated from three replications for each treatment. Bars with different letters are significantly different at P ≤ 0.05 applying Fisher's LSD test.
