The chlorophyll fluorescence induction kinetic analysis method were used to explore damaged position, damaged degree and photosynthetic electron transfer of spinach leaf PSII after Cs stress. The results showed that the OEC on the donor side of the PSII reaction center of spinach suffered slight damage when the CsCl concentration is 1~5 mmol/L. In order to adapt to the change of external environment, the opening degree of active reaction centers in spinach were increased under low concentration treatment, which promotes the increase of PSII photosynthetic activity were reflected by the rised parameters of φPo,φEo,Ψo. Photosynthetic electron transport were blocked because of the damage on the PSII donor side OEC of spinach leaves, reaction center and receptor side of PSII when the concentrations of CsCl reach 10 mmol/L.

The results showed that Yunyan 105 and Yunyan 97 performed much better in Longqing. They had less diseases and disease rate was below 3%. The output value per hectare increased by 20.66% and 13.22% respectively compared with Yunyan 87. They were much suitable for local demonstration and promotion with good ecological. In the Zhuji tobacco area, Yunyan 121, Zhongchuan 208, and Yunyan 207 performed better. Agronomic traits such as plant height and leaf area were better than Yunyan 87 and the output value per hectare increased by 13.57%, 7.14%, and 7.14% respectively compared with Yunyan 87. They were suitable for local planting. In the Caiyunyan area, Yunyan 97, Zhongchuan 208, and Yunyan 207 performed well in field growth. All agronomic indicators of the three varieties were better than Yunyan 87. The output value per hectare increased by 12.59%, 17.48%, and 10.49% respectively compared with Yunyan 87. In summary, Yunyan 105 and Yunyan 97 are suitable for planting in Longqing tobacco area. Yunyan 121, Zhongchuan 208 and Yunyan 207 are suitable for planting in Zhuji tobacco area. Yunyan 97, Zhongchuan 208 and Yunyan 207 are suitable for planting in Caiyun tobacco area.
