In many parts of the world, agricultural use of soils is restricted due to heavy metal
contamination. Absorption of heavy metals, such as (Pb), in the tissue of plants increases the
plant’s metabolism and causes physiological disorders or even death. In order to study the
potential of super absorbent polymers (SAP) and mycorrhiza fungi application to mitigate adverse
effects of lead (Pb) on wheat, a greenhouse experiment was conducted. The experiment was setup
as a completely randomized design, with two treatments arranged in a factorial scheme with three
levels of lead (0, 100 and 200 mg per kg soil) and four levels of SAP and mycorrhiza fungi
application (without SAP and mycorrhiza fungi application, SAP application alone, mycorrhiza
fungi application alone, SAP and mycorrhiza fungi application combined). The results showed
that Pb significantly affected all parameters measured of wheat. The Pb-contamination caused a
significantly decreasing in plant height, total dry weight per plant and total chlorophyll contents.
And also, the results indicated that the combined use of superabsorbent and mycorrhiza reduced
the amount of superoxide dismutase enzyme. As well as, our results show that the application of
super absorbent polymer and mycorrhizal fungi seems to be a promising path to reduce
detrimental effects of heavy metal pollution of agricultural soils on plant performance.
