Figure 1.  Characterization of the two mutant lines, RSD16-1 and RSD32, derived from NaN₃-treated N61.  (A) Comparison of germination rates without exogenous supply of ABA of whole grains at 40 DAP in N61 and the mutant lines.  (B) Comparison of germination rates with or without ABA (100 µM) of half grains containing embryos at 40 DAP in N61 and the mutant lines.  Fourteen seeds per line were assayed, and the whole experiments were repeated three times.  The small bars represent standard errors.
