| Abstract: |
| The effects of NaCl stress on seed germinations and seeding growth of sweet clover were investigated by indoor germination and greenhouse seedling cultivation. The results showed that the seed germination、 cumulative germination percentage、seed germination speed、GW/DW、inhibition index
of root(shoot) length、 seedlings’ total chlorophyll was promoted under the low concentration of NaCl stress， while they were inhibited when the concentrations of NaCl were higher; Seed germination index was inhibited by different NaCl stress. However,the MDA was promoted by NaCl stress. In a word, the seed germinations and seedling growth of sweet clover were promoted under the low concentration of NaCl stress. On the contrary,they were inhibited when the concentrations of NaCl were higher. |
