Abstract: In this study,the tube plantlets of Euonymus japonicus were used for evaluating their salt-resistance abilities through the experiment with different concentration of NaCl.Under the condition of salt stress,the morphological index and the biomass of Euonymus japonicus were affected. As a result of the experiment,the best salt concentration for the growth of test-tube plantlet growing was found. Results showed that the injury index and stress susceptibility indexes were increased as well with the increase of salinity level in the culture medium; When the concentration of the NaCl is smaller or amounts to 0.2%,it can benefit the tube plantlets of Euonymus japonicus especially in fresh weight,root/shoot ratio(R/S)and relative water content which could reach to the maximum value.It indicated that 0.2%NaCI was the best salt concentration for the growth of the test-tube plantlet growing.

Key words: Euonymus japonicus, morphological index, tube plantlet, salt tolerance
