Abstract

Roots of tomato plants were grown for 21 days in complete hydroponic nutrient solution including Fe3+-chelate EDDHA and subsequently switched to nutrient solution withholding Fe for 4 to 5 days to induce iron stress. The iron-stressed plants reduced chelated Fe (measured as ferrozine complex) at rates 7-fold higher than those of roots of plants grown in Fe-sufficient conditions. The response in Fe-deficient plants was localized to root hairs which developed on secondary roots during the period of Fe stress.
