Fig. 1 Root dry weight (A, B) and root-shoot ratio (C, D) at heading time and root oxidation activity during grain filling (E, F) of green super rice Values in the figure are expressed as means ± standard error (n = 3). Different letters on the column indicate statistical significance at P = 0.05 within the same measurement date. NS means not significant at P = 0.05.
