Abstract
In the pot culture experiment, winter wheat (Triticum aestivum L.) c.v. Yanmai 5 was selected to study the effect of long-term water-logging, which was conducted from jointing stage to 20 days after anthesis, on grain weight and membrane lipid peroxidation, and on enzyme activities involving membrane lipid peroxide elimination of wheat leaf and root. The content of MDA (malondialdehyde), the product of membrane lipid peroxidation in flag leaf and root under waterlogging increased significantly, while the activities of SOD (super oxide dismutase) and CAT (catalase), two key enzymes involving in membrane lipid peroxide elimination decreased severely. Thereafter, the wheat flag leaf and root under waterlogging senesced much earlier than those under control. Therefore, the grain filling rate of wheat grown under water-logging condition decreased significantly, and subsequently, its grain weight decreased obviously.
