Abstract :The present study investigates the role of exogenously applied proline on cadmium insert ignore into journalissuearticles values(Cd); accumulation in common wheat insert ignore into journalissuearticles values(Triticum aestivum L.); tissues. Seedlings were subjected for 4 days to different exogenous proline levels insert ignore into journalissuearticles values(0, 1, 10, and 20 mM); under Cd stress insert ignore into journalissuearticles values(1000 μM of Cdinsert ignore into journalissuearticles values(NO3);2·4H2O);. The concentration of Cd, Ca, Mg, and K was determined by inductively coupled plasma optical emission spectrometry insert ignore into journalissuearticles values(ICP-OES);. Exogenous proline caused significant changes in the growth of wheat cultivar under Cd stress. In addition, the growth of wheat under Cd stress increased by the addition of 1 mM proline. According to the analysis results, Cd accumulation in wheat seedlings showed that the increment of exogenous proline treatments insert ignore into journalissuearticles values(except Cd+Pr1); in the water resulted in a decrease of Cd content in roots and shoots. Under Cd treatment insert ignore into journalissuearticles values(not applied proline);, the contents of Ca, K, Mg, and Na decreased in roots by 22.1, 70, 17.7, and 10.1% and in shoots by 29.6, 32.2, 19.1, and 5.3%, respectively. Nevertheless, K content decreased in roots and shoots under all Cd and exogenous proline treatments.
