Four clones of one-year-old cutting seedlings of Taxodium hybrid were used as the tested materials. We designed a new salt treatment method in this research. The effects of NaCl stress on morphological and physiological indexes of T. hybrid clones were studied. We also discussed the mechanism of salt tolerance of T. hybrid seedlings and compared the ability of the salt tolerance of the 4 clones.
The data of the experiments showed that salt concentrations from 125mM to150 mM were the critical sal...
