This experiment was carried out in a private field by using the hydroponic farm of the Faculty of Agriculture - Kerbala University. The experiment was conducted on 2019-2020 growing season. The experiment included three factors: the first factor is four concentrations of cadmium chloride (0,25,50 and100) mg.cd.L−1, and the second factor is four concentrations of lead chloride (0,25,50 and 100) mg.cd.L−1 and the third factor are two varieties of wheat bread (Triticum aestivum. L) variety (Iraq) and wheat coarse (Triticum durum L.) variety (gondola) and with three replications showed the following results: The variety Iraq was superior in all the studied traits, such as root length, root weigh, root size, as well as root diameter) 39.229, 3.362, 5.958, 0.797), The (0T) (0 Cd,0 Pb) treatment excelled in increasing the root length, root weigh, root diameter (45.55, 3.720, 1.018), while the(T1) (0 Cd,25 Pb) treatment excelled in the root size(7.000) while the 2T(0 Cd,50 Pb) treatment excelled in the root length(48.333). The overlap treatment of the gondola variety and its coefficient (T0) outperformed the root diameter(1.038). The overlap treatment (T0) outperformed Iraq in the root size (8.333) and the overlap treatment and the T2 of the gondola varieties outperformed in increasing the root length, root weight (51.333, 4.210) sequentially. *The research is based on the doctoral thesis of the first researcher.

This experiment was carried out in a private field by using the hydroponics unit of the Faculty of Agriculture - University of kerbala. The experiment was conducted on 2019-2020 growing season,The experiment included three factors,the first factor, Was four concentrations of cadmium(Cd) from cadmium chloride CdCl2 (0,25,50 and 100) mg Cd.L−1, the second factor was four concentrations of lead from lead chloride Pbcl2 (0,25,50 and 100) mg Pb.L−1 and the third factor was two varieties of wheat (Iraq) from bread wheat,(Triticum aestivum L.), and (Jandohl) from durum wheat (Triticum durum L.), with three replications, the results showed the following, Iraq variety was superior an increasing the activity of POD, SOD and CAT enzymes and proline, and (100 Cd −100 Pb)mg.L−1 treatment of excelled in increasing the activity of POD, CAT and proline, while the treatment of (100 Cd −25 Pb) outperformed in increasing the activity of SOD, and Iraq variety with (100 cadmium-100 lead) interaction treatment was outperformed in activity of POD, SOD, CAT and proline.
