Fig. 3 illustrates that the SOD activities of L4422 andEG203 showed no significant difference from 0 h floodinguntil the end of the experiment. Additionally, SOD activity
was not significantly different in all entries of different
flooding times. The GR activities of all plants were not significantly
different for the waterlogged periods except for
those of L4422 (Fig. 4). GR activity among entries showed
no significant difference for all flooding treatments, with the
exception of the 6 h treatment (Fig. 4).
