Intensity and duration of salinity required to form adaptive response in C₄ halophyte Kochia prostrata (L.) Shrad.

ABSTRACT: Plant adaptation to salinity is a highly multifaceted process, harnessing various physiological mechanisms depending on the severity and duration of salt stress. This study focuses on the effects of 4- and 10-day treatments with low (100 mM NaCl) and moderate (200 mM NaCl) salinity on growth, CO₂/H₂O gas exchange, stomatal apparatus performance, the efficiency of photosystems I and II (PS I and II), content of key C₄ photosynthesis enzymes, and the accumulation of Na⁺, K⁺, and proline in shoots of the widespread forage C₄ halophyte Kochia prostrata. Our data show that 4 days of low salinity treatment resulted in a decrease in biomass, intensity of apparent photosynthesis, and cyclic electron transport around PS I. It
