Abstract
The effects of salt stress on the seed germination of four cowpea( Vigna unguiculata) varieties( Xiamei 1,Suifeng 5,Suifeng 8 and Suifeng 9) were investigated. Seeds were treated in different concentration of NaCl,and the germination percentage,germination index and salt injury index of the four varieties were compared. The results showed that: Compared with the control,under the condition of NaCl salt stress,different seed varieties had different salt stress reaction. Low concentrations salt stress( ≤25 mmol / L) affected weakly to the relative germination rate of all varieties of cowpea seeds but has stronger impact on relative seed germination index. The relative salt injury rate increased with the increasing of salt concentration. Seed germination and seedling growth of the four varieties was strongly inhibited by 50 mmol / L of salt stress. Comprehensive evaluation of the four varieties indicated that Suifeng 9 had better salt tolerance than other three varieties, Suifeng 5 and Suifeng 8 were inferior,and Xiamei 1 was the most susceptible variety.
