Abstract

Under waterlogging stress at seedling and booting stages, both two wheat varieties, Huamai-8 with stronger waterlogging tolerance and Een-1 with weaker, decrease in chlorophyll (chl) content, superoxide dismutase (SOD) activity, catalase (CAT) activity, root activity and increase in malondialdehyde (MDA) content. The extents of ones in Een-1 are greater than those in Huamai-8. They increase in proline (pro) content too, but to extent, Huamai-8 increases greater. The change of peroxidase (POD) activity is that Huamai-8 increases slowly and continually, Een-1 increases rapidly for several days then begins to decrease.
