Well-aerated and alkaline soils are proven to lack plant-available iron. Fe-efficient plants, however, induce morpho-physiological and biochemical mechanisms of adaptation. These changes in morphology and physiology of the shoot-root systems of peanut (Arachis hypogaea L. cv. NC 2) plants were studied by cultivating them hydroponically in the nutrient solution containing different levels of Fe3+EDDHA (0.00, 0.125, 0.25, 0.50, 1 and 2 ppm). Three types of chlorosis and regreening (I, II, III) on the shoot system appeared simultaneously with three types of rooting (I, II, III) in different stages of plant growth under Fe-free media. The difference in the regreening processes of plants grown in Fe-free and Fe-treated media indicated that their signaling pathways for Fe localization might be different. The morphological responses were found to correlate to three types of regular and rhythmic pH changes in the nutrient solutions. The sites of pH responses and Fe3+ reducing activities in the roots showed dependence on the type of root and shoot morphology.
