Abstract
Wild type Arabidopsis thaliana (ecotype Columbia) and Thellungiella were used as experimental material in this artile. The leaves of the Arabidopsis and the Thellungiella were treated with different concentrations of NaCl. The fluorescence emission spectra, the chlorophyll fluorescence and the delayed fluorescence were detected respectively. We found that there was an obvious change in the photosynthetic efficiency of PS II and the DF intensity of the Arabidopsis leaves with different concentrations of NaCl treatment. However, there wasnot an obvious change in the photosynthetic efficiency of PS II and the DF intensity of the Thellungiella leaves with 100mmol/L and 200mmol/L NaCl treatment. While it also showed that there came to be an obvious stress of the Thellungiella leaves with 300mmol/L NaCl treatment. The fast chlorophyll fluorescence induction dynamics analysis revealed that the photosynthetic efficiency of PS II of the Arabidopsis leaves had a sharp decline along with the 100-200 mmol/L NaCl treatment, While the Thellungiella leaves showed a strong tolerances to salt stress.
