Abstract
With room water culture experiment, chlorophyll content, leaf membrane permeability, relative water content and superoxide dismutase(SOD) activity in seedling stage of five kinds spring wheat under the Na2CO3 stress were studied, and their salinity tolerances were estimated. The results showed that the order of their salinity tolerances was CDHLM26KH14KD4ZGC. Their leaf membrane permeabilities and total SOD activi-ties were in positive correlation with the Na2CO3 stress, and the wheat which has stronger salinity tolerance incre-ased sharply;the relative water content and chlorophyll content were in negative correlation with Na2CO3 stress, and the wheat which has stronger salinity tolerance decreased slowly.
