Abstract: Photooxidative characteristics and physiological mechanism in leaves of super high-yielding hybrid rice Peiai64S/E32 and its parental lines were investigated by photooxidative treatment mediated with 200 µmol/L of exogenous methyl viologen under a PPFD of 2 000 µmol·m-2·s-1 for 1 h. Me

Key words: Super high-yielding rice, Heterosis, Methyl viologen, Tolerance to photooxidation, Chlorophyll fluorescence, Antioxidative enzyme
