Influence of SA on seed germination and seedling establishment of Arabidopsis Ler ecotype. A, Influence of SA on the germination profiles. Seeds were germinated as described in “Materials and Methods,” in the absence (○) or presence of SA (•, 0.1 mm; ⋄, 0.25 mm; ♦, 0.5 mm; ▵,0.75 mm; ▴, 1 mm; □, 2.5 mm; ▪, 5 mm). The graph shows a representative experiment carried out three times in triplicate. B, Phenotypes observed 7 d after sowing on water without SA (a) and with SA (b, 0.1 mm; c, 0.25 mm; d, 0.5 mm; e, 0.75 mm; f, 1 mm; g, 2.5 mm; h, 5 mm). Square, 3 mm × 3 mm.
