Abstract

In the current study, some physiological responses of KOCHIA PROSTRATA to SALINITY stress were investigated. This species is native to Iran and could be used as forage for livestock. Plants were exposed to 0 (control), 50, 100, 150, and 200 mM NaCl. The experimental design was completely randomized design with 4 replications and 5 treatments. To prevent osmotic shock, the treatments were done gradually. After 21 days of the last SALINITY treatment, the plants were harvested and PROLINE, GLYCINEBETAINE, SOLUBLE SUGARS, WATER POTENTIAL and RELATIVE WATER CONTENT were measured. The result showed that in KOCHIA PROSTRATA, with an increase of SALINITY concentration up to 200 mM NaCl, PROLINE, GLYCINEBETAINE and SOLUBLE SUGARS increased. According to the results, this plant tolerates the SALINITY through the synthesis of PROLINE, SOLUBLE SUGARS and GLYCINEBETAINE as the mechanisms of salt tolerance. The high RELATIVE WATER CONTENT of the leaf (RWC) up to 150 mM and significant decrease of WATER POTENTIAL also caused an increase of water use efficiency with low evaporation and transpiration from the leaves.
