摘  要：
[目的]研究多花木蓝幼苗的耐盐性,为生产利用提供参考依据。[方法]选用不同浓度梯度的NaCl溶液对盆栽多花木蓝幼苗定时定量浇灌,每3 d,采集各处理的叶片进行生理指标测定,直到出现盐害症状为止。[结果]在盐胁迫条件下,随着盐溶液浓度的上升和胁迫处理时间的延长,多花木蓝幼苗的相对电导率呈先下降后上升的趋势,叶绿素含量呈下降的趋势,可溶性蛋白质含量和SOD活力呈先上升后下降的趋势。[结论]从盐胁迫第9天开始,浓度大于150 mmol/L的NaCl溶液对所测生理指标的影响最大。

摘  要：
[Objective]To research the salt stress of Indigofera amblyantha seedling,and to provide references for the application of I. amblyantha. [Method]I. amblyantha pot seedling were poured by NaCl solution with different concentration. Taking leaves of each treatment every 3days to measure physiological indicators from the start date of salt stress until the salt injury symptoms appear. [Result]Under salt stress,with the increased concentrations of salt solution and days of stress,the value of I. amblyantha seedling's relative conductivity has a decreasing trend at first but then,has an increasing trend. The chlorophyll content has a decreasing trend,the soluble protein content and SOD activity have an increasing trend at first but then,both of this two indicators have a decreasing trend. [Conclusion] The NaCl solution with more than150 mmol / L has the greatest influence on the measured physiological parameters from the ninth day of salt stress.
