Salix gracilistyla is widely distributed in relatively stable riparian zones such as the waterfronts of natural wetlands in Korea, and it demonstrates rapid growth of branches and root and rapid asexual propagation. For purpose of potential for utilization on unused land including reclaimed land using S. gracilistyla which is stem cuttings and potted plants were exposed to different concentration of NaCl solution. Stem cutting were socked in NaCl solution, and potted plants were watered as solution to plants by periods. In the NaCl absorption of stem cuttings, 0.1% NaCl treatment did not affect the rooting. However, 0.2% NaCl treatment decreased the rooting to 50%. In NaCl absorption of potted plants, they were able to survive well up to 0.2% NaCl treatment. However, survival rate was decreased to 50% on 0.5% NaCl treatment. Survival rate was decreased under 20% in 0.3% NaCl treatment on stem cuttings and 0.5% NaCl treatment on potted plants. In the NaCl absorption, ratio of Ca2+/Na+, K+/Na+ and Mg2+/Na+ were decreased and caused physiological disorder. In the treatment of high treatment, concentration of chlorophyll a, b and carotenoids were decreased. To investigate clonal effects, ion such as Ca2+, Na+, K+, Mg2+ and ratio between ion were analyzed. It showed as the different concentration in several clones. Three clones which is superior clone at standard of yield more absorbed Na+ than other clones.
