The objectives of this study focused on measuring chlorophyll fluorescence related to drought stress comparing some parameters. Almost parameters were declined although they were not significant on the basis of mean values of fluorescence of total leaf area. While the ratio of fluorescence intensity variable chlorophyll () to fluorescence intensity maximal chlorophyll () was not changed, the effective quantum yield of photochemical energy conversion in photosystemII () and chlorophyll fluorescence decrease ratio () were slightly reduced, indicating inhibition of the electron transport from quinone bind protein A () to quinone bind protein B (). Some parameters such as non-photochemical quenching rate () and coefficients of non-photochemical quenching of variable fluorescence (qN) in mid-zone of leaf and near petiole zone leaf were significantly enhanced within 4 days after drought stress, which can be used as physiological stress parameters. Decrease in could was significantly measured in all leaf zones. In conclusion, three parametric evidences for chlorophyll fluorescence responses such as , NPQ, and qN insinuated the possibility of photophysiological indices under drought stress.
