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.
