Carpetgrass and centipedegrass tissue iron and manganese accumulation in response to soil waterlogging

Abstract

Abstract Soil waterlogging significantly increased the iron (Fe) and manganese (Mn) tissue levels of carpetgrass (Axonopus affinis Chase) and centipedegrass [Ermochloa ophuiroides Munro. (Kunz.)]. Common carpetgrass and centipedegrass survived six weeks of continuous waterlogging. Results suggested that retention of high Fe and Mn levels within or on root tissue may have served as an adaptive mechanism.
