The present study used the seeds and newborn seedings of Salix sungkianica as material, examining the influence of NaCl and NaHCO3 solutions of different concentrations on the seed germination and anatomical structure of the roots and lamina of the seedings. The results indicate such facts: (1) The presents of NaCl and NaHCO3 have a depressant effect on the seed germination, while a light concentration of NaHCO3 could accelerate the sprout. (2) S.sungkianica seedings show strong endurance under the stress of 50 mmon/L NaCl and 10 mmon/L NaHCO3 solutions, the seedings growth are better in 10 mmon/L NaHCO3. (3) Under the stress of such solutions of high concentration, certain degrees of endurance also present in the roots and lamina, with the anatomical results like the thicken of root endodermis, the enlargement of vascular bundle in diameter, the vanish of aerenchyma tissures and the closure of lamina stoma.
