摘　　要：主要是在离体培养条件下,通过研究不同NaCl浓度对北海道黄杨试管苗的形态指标、生物量等的影响,以确定黄杨试管苗最适生长盐浓度。结果表明:试管苗的受害指数、胁迫敏感指数随着盐浓度的升高而增大;当NaCl浓度≤0.2%时,其盐害程度不仅最小,反而还更有利于北海道黄杨试管苗的生长(在0.2%时,北海道黄杨试管苗的鲜重、根冠比以及相对含水量等达到最大值),这说明0.2%的NaCl浓度是黄杨试管苗生长的最适盐浓度。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.
