A kinetic method for determining iron reducing activity released from plant roots

, : A kinetic method for determining iron reducing activity released from plant roots. Journal of Plant Nutrition 3(1-4): 615-623

The development and validation of a new method for determining the iron reducing activity of nutrient solutions supporting plant growth are described. The method depends on the rate at which an aliquot of nutrient solution reduces the iron of Fe3+-nitrilotriacetate (NTA). The reduced iron is bound by bathophenanthroline sulfonate (BPS) and the rate of Fe2+-BPS formation is measured at 535 nm.
