Abstract:

The wheat Yannong No.19 and Kehan No. 16 were used as the experimental materials to study the effect on seed germination and seedling growth under the condition of the NaCl stresses. The results showed that the germination rate, seedling height, root length, seedling weight, root weight and root number of two varieties in wheat pointed a significant downward trend as the NaCl concentration increases. Seedling weight and root weight was affected greater than other characters by NaCl stress and was significantly lower than the control when the NaCl concentration was 25mmol/L and 50mmol/L according to different varieties. Two varieties of wheat have shown varying degrees of tolerance to NaCl. Yannong No.19 tolerates NaCl better than Kehan No. 16.
