Effect of salinity in Arabidopsis seedlings growth. (a) Appearance of 14-day-old Arabidopsis seedling growth in MS medium supplemented and nonsupplemented with 100 mM NaCl. (b) Primary root length. Results are the mean of three different experiments ± SEM. *Differences in relation to control values were significant at P < 0.05. (c) Histochemical detection of plasma membrane integrity by staining with Evan blue solutions. Blue colour (arrows) indicates the root area where the membrane integrity is affected by salinity.
