Intracellular copper and cadmium uptake increased due to increased metal availability in the 5 mM HEPES buffer for 24 h. Assimilation pigments, chlorophyll a fluorescence, malondialdehyde (MDA) content and photosynthetic oxygen evolution rate (OER) were sensitive to the presence of redox-reactive metal Cu2+ in short-term experiments. Cd2+ decreased FV/FM values indicating damage to PSII and decrease of OER. However, assimilation pigments and MDA content were not altered significantly. ER -
