Osmotic and ionic stresses were the primary instant damage produced by salt stress. They can also bring about other secondary stresses. Soybean is an important economic crop wild soybean aroused increasing attention for its excellent performance in resistance. For this reason, we compared different performances of Glycine max L. (ZH13) soja (BB52) both young mature seedlings, hoping to clarify specific reasons. Our research revealed that, cultivated soybean, was able maintain higher water potential relative content (RWC), accumulate more amount proline glycine betaine, reduce contents Na + Cl − faster efflux, cut down efflux K as well keep /Na ratio. And what almost all excel behaviors became particularly obvious under NaCl concentration (300 mM). Therefore, according detections comparisons, concluded that had tolerance mechanisms better It should be used eminent germplasm resource enhance resistant ability or even crops.
