Abstract: The sensitivity to photoinhibition and its mechanism were compared between super high-yield rice Peiai64S/E32 and indica hybrid Shanyou 63. After strong light treatment, the maximal photochemical efficiency of PSⅡ (Fv/Fm), the quantum efficiency of PSⅡ (ΦPSⅡ) decreased less in Peiai64S/E32 than

Key words: Super high-yield rice, Photoinhibition, 77K fluorescence spectra, D1 protein turnover
