摘要: 本实验以北京广泛种植的三个大豆品种:早熟18、中作95-888M3、中作95-888M3绿粒变异为材料,比较研究了在5%、10%、15%、20%、25% PEG6000渗透胁迫下大豆植株体内NR、CAT、POD活性,以及chl、游离pro含量的变化。结果表明,在5%PEG6000渗透胁迫处理下,各生理指标出现了显著性差异。实验室模拟干旱处理的最佳PEG6000浓度为15%。

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%.
