Different physiological characteristics and elemental parameters of Aeluropus littoralis were trended during salinity stress (600 mM NaCl) and recovery. A chlorophyll a (Chl a), B chlorophyll b (Chl b), C total chlorophyll (Chl (a + b)), D chlorophyll a to chlorophyll b ratio (Chl a/b), E carotenoids (Cars), F total chlorophyll to carotenoids ratio (Chl (a + b)/Cars), G Sodium (Na+), H potassium (K+), I calcium (Ca2+), J magnesium (Mg2+), K sodium to potassium ratio (Na+/K+), L sodium to calcium ratio (Na+/Ca2+) content. The trend in leaf, root and stem tissues was illustrated by the red, blue and black lines, respectively. The values represent the mean (± SE) of three biological replicates. According to Duncan's multiple test, the treatments exhibited a statistically significant difference at the 5% level and were marked with distinct letters
