Abstract

The influence of salinity on the activity of antioxidant enzymes in the leaves and roots of two genotypes of sweet potato is studied. It is shown that the reaction of systems providing protection against the damaging effect of salt shock varied depending on the location of antioxidant enzymes in plant organs. In the leaves, the activity of ascorbate peroxidase (APO) was significantly higher than in the roots, and the activity of guaiacol peroxidase (GvPO) in the roots was significantly higher than the activity in the leaves of both genotypes. The activity of APO and GvPO had a different level of accumulation in the leaves and roots of sweet potato in all periods of exposure to salt shock, which in the complex had a significant role in neutralizing the active forms of oxygen (ROS) formed under conditions of elevated NaCl concentrations.
