AbstractAn experiment was conducted by using pots in greenhouse of the Department of Biology ,College of Education (Ibn Al_haitham ) University of Baghdad during the growing season of 2008-2009 .The experiment aimed to demonstrate the effect of increasing concentrations of both Sodium chloride and proline acid and their interaction on some yield components of wheat cv.Ibaa99.
The experiment included four concentrations of Sodium Chloride 0,50,100and150 mML and four concentrations of proline acid 0,10,20and30 ppm. The experiment was designed as Completely Randomized Design (CRD)by three replicates(3×4×4)consisting 48 exp.units.Data were statistically analyzed to find out the least significal differences (LSD) between treatment at 0.05 level .Results indicated that increasing of Sodium Chloride concentration form 0 to 150 mML caused significant decreases in yield components (biological yield, Spike length,number of spikeletsspike,number of grainsspike,weight of 1000 grain and grains yieldlpot. The treatment with proline acid indicated significant increases in all averages of yield components.
Results of interactions for both factors indicated that foliar application of proline acid counteracted the adverse effects of high concentrations of Sodium chloride o f yield components of the plant.
