Effect of salt stress on hull area of in vitro- and soil-grown Arabidopsis and E. salsugineum. A, In vitro. B, Soil. Data are mean ± sd (n = 3, in vitro; n = 8, soil). Each replicate in vitro plate contained approximately 15 seedlings. Only E. salsugineum plants could be grown on soil under 300 mm NaCl. Data are representative of similar results from two independent experiments. Bars with different letters (uppercase, Arabidopsis; lowercase, E. salsugineum) indicate significant difference at P ≤ 0.05 (Student’s t test). Each species was statistically analyzed separately between all salt levels.
