Chlorophyll (Chl) a and b content, ribulose-1,5-bisphosphate arboxylase/oxygenase (RuBPCO) content and activity, and electron transport rate were measured in flag leaves of wheat genotypes Uniculm and Kalyansona, grown at suboptimal and optimal supply of nitrogen. The Chl content, RuBPCO activity, and electron transport rate were decreased due to suboptimal nitrogen supply only in Kalyansona. There was no change in the ratio of RuBPCO and phatosystem 2 (PS2) activity at various stages which suggests that there was no alteration in distribution of N due to additional N supply.
