| Abstract: | Soluble protein, free animo acid and free proline content of germinating Puccinellia tenuiflora seeds under different concentration of Na 2CO 3 stress was studied. The results indicates: in the salt free condition, soluble protein and free amino acid content increased gradually along with the germination process, proline content increased rapidly in earlier period and then keep stable; soluble protein and free amino acid content decreased under Na 2CO 3 stress compared with that in Na 2CO 3 free condition and had significant negative correlation with Na 2CO 3 concentration. Proline content showed a different tendency with total free amino and increased on different level under different concentration of Na 2CO 3 stress compared with that in Na 2CO 3 free condition. |
