초록

This study was conducted to investigate the potentials for the forest restoration on reclaimed land by using willow trees (Salix koreensis Anderson) selected from a coastal reclaimed land made in inside of the Sihwa tide embankment. We first collected six individual willow trees that were the only tree species grown in the reclaimed land. Total 7 clones fromcuttings of the collected trees and the control were grownin a greenhouse fortwo months priorto applying the different concentrations of NaCl solutions (0.0%, 0.1%, 0.5%and 1.0%).
Onemonth afterthe NaCl application, the survival rates of clones fromboth the collected trees and the control were significantly decreased in a NaCl dose-dependentmanner. However, there was no significant difference between the collected trees and the control in terms of survival rate, hight and diameter of cuttings, and the numbers of leaves in greenhouse condition. In conclusion, the willow trees collected from the coastal reclaimed land showed no tolerance against NaCl compared to the control grown in ordinary soil, suggesting that further study is required to determine what the most important factoris to select salt tolerant tree species
