- 摘要:
- 为探讨盐胁迫下绿化树种的生长规律和育苗技术，研究了不同浓度盐胁迫对绿化树种水蜡和金叶女贞生长的影响。结果表明: 随着盐胁迫浓度的增加，两树种地径、苗高、新梢粗、新梢长和叶面积增加量逐渐减小，金叶女贞的耐盐性略强于水蜡，金叶女贞和水蜡相对适应生长的盐浓度均低于0.3%。
- Abstract:
- In order to explore growth law and seedlingraising technique of greening tree species，effects of salt stress on growth and physiological characteristic of? Ligustrum vicaryi and? Ligustrum obtusifolium ?were studied.The results showed that with the increasing of salt concentrations，the increment of ground diameter，plant height，shoot diameter and shoot length decreased，the salttolerance of Ligustrum vicaryi ?was better than Ligustrum obtusifolium.The adaptive salt concentration for Ligustrum×vicaryi and Ligustrum obtusifolium ?were less than 0.3%.
