EFFECT OF SODIUM CHLORIDE AND PROLINE ACID ON SOME GROWTH PARAMETERS OF WHEAT PLANT Triticum aestivum L.

Abstract

Pots experiment was conducted in the glasshouse of Biology Department,College of Education Ibn-AL-Haitham/ University of Baghdad. The purpose of this research is to study the effect of Sodium Chloride ( 0,50,100,150) mM.Lˉ¹and Proline acid (0,10,20,30)PPm and their interactions on some growth parameters included:Plant hight , Leaf area , Sodium and Chloride concentration and the content of total Chlorophyll of wheat plant cultivar Ibaa 99. The results indicated that Salinity stress affected plant growth and caused a significant decrease in the mean of studied growth parameters ,morover foliar sprying with Proline acid caused a significant increase in the mean growth parameters.The interactions was significant in which the results indicated that foliar sprying with Proline acid increased plant ability to tolerate Sodium Chloride effect.
