The effect of sulfur-containing compounds and thiobacillus bacteria on corn plants under field soil and soil contaminated by heavy metals lead and zinc conditions

Investigating the effect of various sources sulfurous compounds along with inoculation Thiobacillus bacteria on corn plants under stress conditions lead and zinc metals, an experiment executed at zanjan uni researching green house. The treatments include elemental sulfur (0.75, 1.25 2 g/kg soil), (1, 3 soil) potassium sulfate (0.5, 1 1.5 soil ). results showed that traits were significant in all applied except proline. amount morphological physiological increased treatment thiobacillus field heavy metal compared to control. But properties soluble sugars proline decreased this treatment. On other hand, increase concentration caused plant. However, conditions, absorption root aerial part plant a critical damaging level, but by applying treatments, damage decreased. it can be concluded reducing elements required stress, reduces these elements, provides for absorbing more water nutrients through roots improves growth
