Protection of plants from oxidative destruction is associated with active<br />
functioning of SOD activity in roots and leaves under waterlogging conditions<br />
(Zakrzhevsky et al., 1995).<br />
Many plants are able to survive stress conditions when antioxidative enzymes<br />
is not the long - term and the active functioning of enzymes-detoxicators i.e. SOD<br />
is effective.<br />
