Effects of NaCl and Hoagland nutrient solution concentration (EC in dS m⁻¹) at 38 days after sowing (DAS) on: a rosette dry weight, b root dry weight, c rosette fresh weight, d rosette:root ratio, e dry matter % and f root length (n = 6) (Exp. 3). Red (Hoagland) and grey (NaCl) bands represent the confidence interval of the spline function (red and black lines) fitted to the data. Symbols represent the means and are averages of 6 true replicates and each replicate is represented by 4 plants, i.e. 24 data points per mean. Error bars represent the standard deviation of the mean. Data points of EC 16 and 32 dS m⁻¹ are excluded as plants died during early development
