EFFECTS OF NaCl STRESS ON LIGHT UTILIZATION AND DISSIPATION OF PSII

Zhu Xinguang Zhang Qide Kuang Tingyun(Institute of Botany, Chinese Academy of Sciences, Beijing, 100093)  
Method of fluorescence induction kinetics was used to investigate the effects of NaCl stress on the utilization and dissipation of light energy by PSII. Results showed that: at relatively low light intensity, compared with the control, 100mmol/L and 200mol/L NaCl treatment, 300mmol/L and 400mmol/L NaCl treatment showed lower photochemical quenching, but higher non-photochemical quenching, higher content of the QB-nonreducing reaction center and Fo quenching,while at relatively higher light intensity, the non-photochemical quenching and Fo quenching was relatively lower than the control, 100mmol/L and 200mmol/L NaCl treatments.
