| Abstract: | The changing regularity of membrane oxidation and enzyme activity was discussed under various salt-alkaline stresses by using one-year-old cutting seedlings of the main popular varieties in the west of northeast region as testing materials. The salt resistance capacity and salt tolerance mechanisms were studied, and the capability of adapting and salt-alkali-tolerance of varieties were evaluated synthetically. The results showed that with the increasing of salt concentrations and pH, all physiological indices changed regularly. |
