Globally, soil and water salinities are serious problems for growers. This is especially true for Iran, where 55% of all the agricultural
lands are affected by high soil and water salinities. Salt accumulation negatively affects water and ion transport throughout the
soil–plant–atmosphere continuum (Kafi and Rahimi, 2011).
Tester and Devenport (2003) found that due to osmolarity of
external solution, salt stress reduced shoot growth and in a less
magnitude root growth. Reduced growth was due to decreased
in life span of the leaves as they showed necrosis caused by salt
stress and decreased in leaves life span and productivity resulted
in decreased photosynthesis and growth (Tester and Devenport,
2003; Kafi and Rahimi, 2011). On the other hand, the first effect of
the salt stress on plants is a reduction in leaf surface area (Parida and
