The drought tolerance of different wheat genotypes of Triticun aestivum L. grown in field was investigated using two different methods - O2 evolution and prompt Chl a fluorescence. It was found that under mild water deficit (10-15%) the PS2 efficiency was slightly affected. However, under severe water deficit (25-30%) PS2 is strongly inhibited and even injured.
