UV-B-induced damage in such leaves could be reduced with 0.5 mmol.L-1 NaHSO3 treatment; brown spots on the leaf surface were reduced in number, the degree of leaf wilt was reduced, degradation of chlorophyll and carotinoid was reduced and flavonoid level was increased. With the NaHSO3 treatment, the content of H2O2 in leaves of Phaseolus vulgaris under enhanc ed UV-B radiation was significantly lower than in controls, and the activities of antioxidant enzymes were higher with treatment than in controls.
