摘要

[目的] 在对生态城河岸带树种造林成活率调查、分析的基础上

筛选耐盐性树种并对其抗盐性进行研究

为滨海盐碱地河岸带造林树种选择提供依据。[方法] 设置CK

1.5‰

3‰

6‰

8‰

11‰

6个土壤盐度处理

分析盐胁迫对刺槐、杜梨、国槐、绒毛白蜡、臭椿5个树种种子萌发、苗期生长的影响。[结果] 随土壤盐度的加剧

5种种子的萌发能力均受到显著抑制

出苗率、出苗指数大幅降低。苗期生长过程中

国槐受盐害症状表现最严重

其后从重到轻依次为杜梨、刺槐、臭椿、绒毛白蜡。植株叶片质膜透性、丙二醛含量随着盐胁迫程度增加显著上升;总叶绿素含量呈总体下降趋势;脯氨酸含量呈先升高后降低的变化规律。[结论] 根据隶属函数法综合评价5个供试树种的耐盐性

其由强到弱的顺序为:绒毛白蜡 > 臭椿 > 杜梨 > 刺槐 > 国槐。

Abstract

[Objective] Studying the salt-tolerant capacity of tree species in the riparian zones in order to provide a support for the selection of afforestation species suitable for this zone. [Methods] Based on the previous investigation of survival rate of planted species in the riparian zones

five species(Locust

P. betulaefolia

pagoda tree

velvet ash and Ailanthus) were selected for the experiment in salinized soil. We studied the responses of germination and growing indexes of five species to salt stressed soils with different slat concentrations(CK

1.5‰

3‰

6‰

8‰

11‰). [Results] With the increasing of salinity

the seed germination rate and emergence index decreased significantly. Pagoda tree showed the most serious symptom under salt stress

followed by P. betulaefolia

locust

Ailanthus and velvet ash. Membrane permeability and MDA contents of the five species increased remarkably. The contents of chlorophyll showed a decreased tendency with the increasing of salt concentration. The content of proline increased under low level of salt stress and decreased under high level of salt stress. [Conclusion] Subordinate function analysis showed that the salt-tolerance of velvet ash is the best

followed by Ailanthus

P. betulaefolia

locust and pagoda tree.
