Table II.

The amount of Cu and Fe in the control and Cu-treated bean plants and in the plants grown with excess Cu and Fe

Treatment Color kPI Fe in Leaves Cu in Leaves
h−1 mg/kg dry wt
Control leaves Green 0.28 ± 0.03 242 12

4 μm Cu2− plus 113 μm Fe2+ Green 0.32 ± 0.02 142 22

Three trifoliate leaves collected from separate plants were pooled for the measurement of basic elements. The rate constant of photoinhibition, kPI, was determined on the basis of photoinhibition experiments at PPFD of 1,000 μmol photons m−2 s−1. The kPI values show mean and se of six independent experiments.
