%X Chenopodium glaucum L. is an annual economic halophyte widely distributed in middle and low saline-alkali land. In order to elucidate the response of C.glaucum L. to different contents of NaCl treatment, we studied the effect of seed germination and seeding growth and Na+ content in roots, stems and leaves of the plants under different NaCl contents. With the increase of NaCl, the seed germination rate and the number of seed germination per unit time were declining, and the germination time of the seeds were prolonging compared with the control group. The seeds did not germinate under 500 mmol·L-1 NaCl and the optimum content for germination was 50 mmol·L-1, followed by control and 100 mmol·L-1 NaCl. The plants treated with high bloom(fructify) sooner than the untreated or low concentration treatment. With the increase of the NaCl in substrate, the amount of Na+ secreted in plants showed an upward trend and reached the highest value when the treatment concentration increased to 200 mmol·L-1, evidently in leaves.
