Mutants of hai-1 were insensitive to ABA in seed germination inhibition. a Germination for ABA dose–response was scored at 3 days after cold treatment. b Over-expression transgenic mutants 35S::HAI-1 showed lower seed germination kinetic profiles with 0.1 μM ABA. c The green cotyledon percentage kinetic profiles of various mutants and wild type are shown in the presence of various ABA concentrations (0, 0.1, 0.3 or 0.6 μM) at 7 days after cold treatment. Values are averages ± SD (n = 40–50), three replicates. *P ≤ 0.05, **P ≤ 0.01
