Fig 1. The effect of salinity stress on the selected accessions.

Fig 1

(A) Col-0 and the selected accessions seedlings exposed for 6 days to a medium containing 0 mM (uppermost panel), 150 mM (upper panel), 180 mM (middle panel) and 200 mM (lower panel) NaCl. a: Col-0; b: Mog-11; c: Looe-2; d: Wil-1; e: Bs-1; f: Nd-1; g: Sav-0; h: Got-1. Bar = 0.5 cm. (B) Elongation of the primary root of Col-0 and the selected accessions after a 9 day exposure to 0 or 150 mM NaCl. Values represent the mean percentages of root length achieved in the absence of NaCl stress. (C) Bleaching of the cotyledons of Col-0 and the selected accessions exposed for 6 days to 200 mM NaCl. (D) Chlorophyll content of Col-0 and the selected accessions exposed to 200 mM NaCl for 5 days. (E) MDA content of Col-0 and the selected accessions exposed to 0 or 200 mM NaCl for 36 h. All experiments were run in triplicate and involved at least 20 seedlings per assay. Values given as mean ± SE (n = 3). Significant differences from the performance of Col-0 accession are indicated by * or ** (P < 0.05, P < 0.01).
