Highly significant temporal variations of salinity, Na
content were observed in the habitat. Although quantity of major amino acids was significantly different in leaves, stems and roots of
Rott. ex Willd., their concentrations did not reflect any temporal effects. Accumulation of sugars in vegetative organs and their fluctuations were not significant for thin leaved species
, but their content in
was affected by temporal changes. Amounts of Na
in plant organs were positively related with changes in salinity and mineral ion composition of the habitat. Two species remarkably differed in accumulating amino acids, sugars and mineral ions.
