Abstract. For examining the content of proline, phenolics and anthocyanin in radish (Raphanus sativus L. cv. Pusa chetki), field experiments were conducted under artificial exposure of 1306 μm-3 SO2 in closed polythene chambers for 2 h at alternate days. On prolonged exposure, significant increase in proline, phenolics and anthocyanin content was observed. SO2 gas is absorbed in mesophyll through stomata and alters the metabolic processes of plants and cause abiotic stress. Proline has been shown to protect plants against free radical induced damage which accumulation is linked to quenching of single oxygen. Total phenolics typically have high oxygen radical absorbance capacity (ORAC) value, which helps in amelioration of SO2 phytotoxicity. Anthocyanins have been suggested to act as potent antioxidants. So, proline, phenolics and anthocyanins can play important role against abiotic stress.
