摘要：

为了了解射干和鸢尾对盐胁迫的适应性。以射干和德国鸢尾为试验材料，比较了NaCl胁迫下这两种植物的生理生化指标变化，为植物抗盐研究提供依据。结果表明：两种植物的SOD活性在0.1%和0.3% NaCl浓度下一直呈上升趋势，在0.5% NaCl浓度下呈先上升后下降的趋势，但下降的幅度不同；两种植物的MDA含量一直呈上升趋势；两种植物的叶绿素含量在0.1%和0.3% NaCl浓度下先升高，后随着胁迫时间的延长而下降，而在0.5% NaCl浓度下一直呈下降趋势。这表明，射干和德国鸢尾对盐胁迫有抵抗能力，但射干的抵抗能力要高于德国鸢尾。

Abstract:

In order to investigate the reaction and adaptation of Belamcanda chinensis and Zirs germanic. taking Belamcanda chinensis and Zirs germanic as test materia in this article, the physiological and biochemical index changes of two plants were compared under the NaCl stress and which provided a basis for the study on the function of the salt-resistance of plants. The results showed that SOD and the soluble sugar of two kinds of plants had an upward trend in 0.1% and 0.3% NaCl concentration, the concentration of 0.5% NaCl was decreased, but the decline was different; Two species of MDA content had been on an upward trend; Two kinds of plant chlorophyll content had increased in 0.1% and 0.3% NaCl concentration, with the stress time decreases, while had been on a downward trend in 0.5% NaCl concentration. This show of Belamcanda chinensis and Iris germanica resistance to salt stress, but the resistance of Belamcanda chinensis was higher than that of Iris germanica.
