The excess of Ni in the environment causing significant alterations in plant growth and development, carbohydrate metabolism, increased activity of peroxidase (POD) in leaves, roots and apoplast of these organs. Lower POD activity in leaves and apoplast under Ni environmental pollution of SO42- anion compared to Cl- anion, especially in water culture conditions, demonstrates the interdependence of the Ni cation and anion that accompanies it on the cation in solution nutrition: increased toxicity in the form of chloride Ni compared to sulfate. POD activity in leaves, roots and apoplast of these organs is in the close interdependence of changes in plant metabolism and are crucial in the expression level of tolerance of plants to increasing doses of nickel in the environment. This interdependence is manifested both in optimal soil moisture conditions (70% WSC), and temporary water stress (35% WSC). |
