Abstract :
In order to study effect of super absorbent polymer application to mitigate adverse effects of nickel (Ni), a greenhouse experiment was conductedin Varamin, Iran during the growing season of 2016 in wheat. The experiment was installed in a completely randomized design, with treatments arranged in a factorial scheme with three levels of nickel (0, 60 and 120 mg per kg of soil) by three levels super absorbent polymer application (with out super absorbent polymer application (Control), 2 and 4 g per kg of soil), with three replicates. The results showed that nickel treatment significantly for all experimental traits. The nickel contamination caused a significant decreased plant height, total dry weight per plant and root dry weight per plant at by 8.51%, 31.52 and 56.06% respectively to control, Whereas, increased proline content, superoxide dismutase enzyme activity and the accumulation of nickel in leaves. Also the results showed that super absorbent polymer application increased plant height, total dry weight per plant and root dry weight per plant whereas, decreased proline content, superoxide dismutase enzyme activityand the accumulation of nickel in leaves. Generally the results of the present study indicate that super absorbent polymer application reduces the harmful effects of nickel stress and super absorbent polymer application treatment decreased oxidative stress in wheat plant
