Abstract: Taking the three species of soybean widely planted in Beijing as the material, we compared the activity of NR, CAT and POD in the plant of the soybean at the osmotic stress of the five different concentration of PEG6000, analysed the content of the chlorophyll and free proline. The results indicated that all of the indexes had shown a significant difference under the treatment of the 5% of PEG6000 by the distinct analysis. The most appropriated concentration of PEG6000 in the simulation of aridity treatment in the laboratory was 15%.
