Abstract
Environmental stresses are one of the most important factors of agricultural products reduction in the world. The influence of different concentrations of nickel nitrate (0, 100, 200 and 500 μM in Hoagland’s solution) on dry matter, catalase enzyme, flavonoids, hydrogen peroxide, peroxidase Enzyme, MDA and accumulation of Ni were studied in coriander (Coriandrum sativum) plants. Treatment with Ni led to significant increase in flavonoids, hydrogen peroxide, MDA and other aldehyde. Exposure of coriander plant to Ni altered catalase enzymes, leading to significant decrease in their contents. In both shoots and roots of coriander plants, significant decrease in dry matter was observed. Ni accumulation increased significantly in shoots and roots. Ni increased in the roots more than the shoots. According to a more accumulation of Ni in the roots, the expansion of plants root can help to better adaptability with the toxicity of metals. It may be used as an indicator to illustrate the differences between plant species.
