| Abstract: | Super high-yielding hybrid rice cultivars ‘Peiai64S/E32’ (peiai64S×E32) and its parents were used to investigated the photosynthetic characteristics grown in the field in South China. It was shown that Peiai64S/E32 had greater capacity and higher efficiency for light energy absorption, transforma |
