Abstract

Abstract: Using sophia（Descurainia sophia）, shepherd′s purse （Capsella bursa-pastoris （Linn.） Medic） and wheat （Triticum aestivum L.） as experimental plant,through the hydroponic experiments, the contents of relative conductivity, free proline, soluble protein, peroxidase（POD）, superoxide dismutase（SOD）, malondialdehyde（MDA） in sophia, shepherd′s purse, Wheat under drought dress were studied. The results showed as follow： under drought stress, the relative conductivity, malondialdehyde and free proline of sophia, shepherd′s purse and wheat showed a continuous increasing trend. The relative conductivity of the three plants were wheat>shepherd′s purse>sophia. Under drought stress, the indexes of soluble protein, peroxidase and superoxide dismutase in the three plants showed a trend of rising first and then decreasing. There was a significant positive correlation between free proline accumulation and relative conductivity in sophia and shepherd′s purse. There was a good linear relationship between the two indicators. The results showed that all the three plants had certain tolerance and resistance to drought stress, and the drought resistance of sophia and shepherd′s purse was stronger than that of wheat.

Key words: drought stress（Descurainia sophia）, sophia, shepherd′s purse （Capsella bursa-pastoris （Linn.） Medic.）;, wheat（Triticum aestivum L.）, physiological and biochemical characteristics
