Influence of copper on root exudate patterns in some metallophytes and agricultural plants

A hydroponic experiment was carried out to determine the root exudation patterns in two Cu-metallophytes ( Oenothera picensis and Imperata condensata) and two agricultural plants ( Lupinus albus and Helianthus annuus). Plants were grown in nutrient solution at increasing Cu doses (0, 0.125, 0.25, 0....
