Abstract: Experiments were conducted to study the effects of arsenic on various biochemical parameters, such as chlorophyll, carbohydrate content, free amino acids and molecules concerned with peroxidation (H2O2, MDA), proline, antioxidative enzymes (SOD, CAT, APX) and invertase. Seeds were pre-hardened (HS) by presoaking in KNO3 for 6-8 h, dried at 25 °C. Seeds (NHS and HS) were sown in petri dish lined with filter paper and incubated in BOD incubator. They were periodically treated with the solution of sodium arsenate of two concentrations (0.5 and 1 mM). The seeds germinated in water alone are treated as control. The results showed that there was a considerable decrease in the chlorophyll, carbohydrate content, free amino acids and invertase, while H2O2, MDA, proline and antioxidative enzymes (SOD, CAT and APX) increased under the heavy metal treatment. Proline also enhanced markedly in HS treated with heavy metal. The data are discussed with the available literature.
