Effects of Salt Stress on Germination of Arabidopsis thaliana Seeds
In order to study the influence of salt stress on seeds germination of Arabidopsis ttudiana (L.) Heynh., Columbia wild-type A. thaliana seeds were used as materials and inoculated into MS basic medium with 50, 100, 150, 200 mmol/L NaCl, 50, 100, 150, 200 mmol/L KC1, and 100, 200, 300, 400 mmol/L mannitol under the sterile conditions. Statistics were carried out for the seed germination rate for seven days. Results showed that when the concentration of NaCl, KC1, mannitol was 50, 50, 100 mmol/L, respectively, the seed germination rate was not significantly different from the control. When the concentration of NaCl, KC1 and mannitol reached to 150, 150 and 300 mmol/L, the seed germination rate was significantly lower than the control. With the increase of salt concentration in medium, the inhibitory effects on A. thaliana seeds germination and seedling growth were increased.
