Schematic showing experimental treatments for Swingle citrumelo seedlings grown in nutrient solution with varying nitrogen (N; N-experiment) or calcium (Ca; Ca-experiment) levels for 75 days followed by 15 days in various copper (Cu) concentrations. During the first 60 days of the experiment, plants did not receive Cu supply. Legend: high-N: 16.4 mM N; control (adequate-N and -Ca): 9.4 mM N and 5.7 mM Ca; low-Ca: 1.0 mM Ca.
