Influence of waterlogging on antioxidant metabolism in ragi and rice
2014
Kulkarni, S.S.
Effect of waterlogging (for 4, 8 and 12 days) on antioxidant metabolism in roots and leaves of ragi and rice plants was investigated. In roots of both species, peroxidase activity was increased due to waterlogging. Activity of catalase was reduced in both roots and leaves of ragi in response to waterlogging. In case of rice, catalase activity was decreased in roots while in leaf it increased. In the leaves there was reduction in peroxidase activity. In roots of both species, waterlogging caused an increase in ascorbate peroxidase activity. Waterlogging caused elevation in total polyphenol content especially in the leaves of ragi while in roots of both species a decline in level of these compounds was recorded. In case of ragi ascorbic acid content was increased in leaves and decreased in roots due to waterlogging treatment. A decline in ascorbic acid content in both roots and leaves was noticed in case of waterlogged rice plants.
