Correlation between salt tolerance index (ST) and the relative water fraction (RWF) in Arabidopsis thaliana ecotypes. Plants were grown in hydroponics for 4 weeks according to Conn et al. (2013), and subjected to 7 d of salt stress after increasing salinity to 125 mm NaCl over three increments separated by 12 h each. CaCl2 was added to the medium to maintain constant Ca2+ activity.
