The soil contamination by heavy metals is one of the environmental problems of the world, with deleterious effects on the fauna and flora of soil and groundwater contamination, in addition to reducing plant growth and yield by entering the food chain,  it puts human health and other organisms in denger.Cadmium is one of the hazardous and carcinogenic pollutions that in natural ecosystems ratio increased by human activities and incresment lead to impaired growth and reactions of cells stop.Also foliar micronutrients (iron and zinc) as a solution by many researchers for increasing yield under stress has been proposed.For this purpose, a factorial experiment in a completely randomized design with three replications was conducted in 95 Ardebil Mohagheg University .Treatments included wheat genotypes resistant (Karim) sensitive (Gonbad), cadmium levels (zero, 75, 150 micro-molar) and spraying the stem elongation stage in four levels (iron, zinc, iron + zinc and control) for each concentration was 3 per thousand .The results showed that 150 mM cadmium in both cultivares reduced the photosynthetic pigments and proline incresment, but the reduction was lower in the Karim.Also foliar spray of iron + zinc leads to an increase in proline content and photosynthetic pigments increased resistance is Karim. So it seems to increase proline content in the Gonbad can help to increase resistance to stress this cultivar.
