Abstract: Through inspecting physiological indexes and plant height of G series salt-tolerant rice varieties of field screening, we canfurther appraisal salt resistance of new screening salt-tolerant rice varieties. We cultivate rice seedlings by sand culture method. The ricein growing period of seedling and were treated with different concentrations of NaCl(0.3%, 0.6%, 0.9%)and clear water. The former, wemeasured MDA content, Pro content, SOD activity and palnt height in the third leaf stage. The above 4 indicators were measured in third day andsixth day, which begin to run from the day of pouring salt water. With the salt concentration increasing in the two treatments, the MDA contentin H5、H6 were gradually decreased, however, in the same watering conditions are lower than the control G6 ;Pro content increased gradually,However, in the same watering conditions are higher than the control G6 ;SOD content increased first, and then decreased, however, in the samewatering conditions are higher than the control G6. There were significant change in MDA content, Pro content, SOD activity and palnt height.The study was obtained that G series salt-tolerant rice varieties of field screening were stronger than the control G6. The results indicate thevalidity of G series salt-tolerant rice varieties from physiological indexes to plant height. Experiments conducted that MDA content ;Pro content,SOD activity and palnt height can be used as physiological indexes and morphological indicators for Identification of Genetic Dissection of SaltTolerance.
