The SOD, CAT and GSH-Px activities were higher in flowers (23.83 U/mg protein; 13.55 U/mg protein; 0.056 U/mg protein) than in the aboveground part (7.08 U/mg protein; 2.58 U/mg protein; 0.008 U/mg protein). GPx activity was higher in aboveground parts (2.20 U/mg protein) and lower in flowers (0.94 U/mg protein). (Table 1).
