Fig. 2From: Salinity tolerance in Australian wild Oryza species varies widely and matches that observed in O. sativaLinear regression of Salinity Tolerance (ST) against: a leaf Na+ concentrations [μmol Na+ g-1 (SDW)] (R2 = 0.75) and b leaf K+ concentrations [μmol Na+ g-1 (SDW)] (R2 = 0.69). ST was calculated as the percentage ratio of mean shoot dry weight (salt treatment, 80 mM of NaCl) divided by mean shoot dry weight (control, no salt) [SDW (salt treatment))/(SDW (control)) x 100]Back to article page
