Abstract
The proline, water, Na+ and K+ ions contents and CO2/H2O gas exchange parameters were studied on two xero-halopytes of the genus Atriplex with different photosynthesis types: A. verrucifera (C3) and A. tatarica (C4) under moderate drought and salinity conditions. It was found that proline plays different roles: it accumulates in C3 species under salinity conditions, participates in balancing the cellular osmotic potential in response to Na+ accumulation, while in C4 species it accumulates under drought conditions, it is the main osmolyte under Na+ deficit.
