NaCl-insensitive germination inhibition of hai-1 mutants as compared to wild-type and over-expression transgenic plant seeds a hai-1 mutants showed more NaCl-insensitive seed germination response at 2 days after cold treatment, b hai-1 mutants showed more green cotyledon percentage in the presence of various NaCl concentrations at 4 days after cold treatment, c seed germination kinetic profiles were determined in the presence of 50 mM NaCl, d green cotyledon percentage kinetic profiles were determined in the presence of 50 mM NaCl. Values are averages ± SD (n = 40–50), three replicates. *P ≤ 0.05, **P ≤ 0.01
