The Copper treatment caused loss (70 %) of chlorophyll content in maize primary leaves. The electron transport activity measurements clearly demonstrated that the existence of multiple sites inhibition in thylakoid membranes. Between two photosystems, photosystem II seems to be more susceptible to copper toxicity (50 μM), than that of photosystem II.
