Fig. 4: SEM-EDS ion distribution maps of K, Cl, and Na in spinach and quinoa EBCs grown under two salinity levels.

Columns show K, Cl, and Na maps; rows (top to bottom) are: ʻGazelleʼ (2 dS m−1), ʻGazelleʼ (25 dS m−1), ʻSeasideʼ (2 dS m−1), ʻSeasideʼ (25 dS m−1), quinoa (2 dS m−1), and quinoa (25 dS m−1). Intensities are displayed as false-color heatmaps, where brighter tones indicate higher relative EDS counts.
