Mercury is a toxic heavy metal and it inhibited PS-II catalysed electron transport activity in a dose dependent manner. 50% loss was noticed with the treatment of 15μM HgCl2. Spectral measurements clearly indicated that there is an enhancement in Fo value due to changes in LHC-II complex of PS-II in maize leaves. There is a positive correlation between the loss of PS-II and Chl a fluorescence which clearly demonstrates that the inhibitory site lies near PS-II reaction centre of maize thylakoids.
