Abstract

Current research focuses on the MECHANISMS of salt tolerance in Atriplex verrucifera. This species is native to Iran, and could be used as forage for livestocks. Plants were grown in 20 cm diameter pots in a growth chamber at 25 ± 2°c, and a 16 hour photoperiod. To determine salinity tolerance in growth phase, plants were exposed to 0 (control), 100, 200, 300 and 400 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 last salinity treatment, the plants were harvested. Result showed that in Atriplex verrucifera, treatments from 100 to 200 mM NaCl increased fresh and dry mass, relative water content (RWC), water use efficiency (WUE) of Atriplex verrucifera increased at 100 to 200 mM NaCl salinity condition compared to the control, but they significantly decreased at high concentration of NaCl. Optimal fresh and dry mass production occurred at a salinity of 200 mM NaCl. The MECHANISMS of salt tolerance in the plant may be balance among ion accumulation, production of GLYCINEBETAINE, PROLINE, soluble sugars and salt excertion for maintenance of pressure potential.
