الملخص EN

Pots experiment was conducted in the green house of the Department of Biology, College of Education (Ibn Al – haithum), University of Baghdad during the growing season of 2008 – 2009 .

The experiment aimed to study the effect of the increasing concentration of both Proline acid (zero ,10,20,30)PPm and Sodium Chloride (zero,50,100,150) mM /L in some physiological characteristics , such as the contents of Nitrogen, Phosphorus , Potassium , Protein percentage , total chlorophyll content and proline acid content .

The experiment was designed as Completely Randomized Design (CRD) by three replicates (3x4x4) consisting 48 pots.

Results indicated that , the increase of Sodium Chloride concentrations from 0 to 150 mM/L caused significant decrease in the average of studied physiological characteristics .

Treatments with proline acid indicated significant increase in the average of physiological characteristics .

Interactions for both factors indicated that, foliar application of proline acid counteracted the adverse effects of high concentration of Sodium Chloride for studied physiological characteristics
