Abstract:
Using hydroponic method,according to the response laws of physiological indices of Eichhornia crassipes under different cadmium stress,0 mg·L-1(CK),0.5,1.0,5.0,10.0 mg·L-1and different temperature,28,24,20,16,10 ℃.By observing the changes of the indexes including the activity of antioxidant enzymes (POD,CAT),the level of chlorophyll,malondialdehyde(MDA) and the root activity.The results showed that under different cadmium stress,temperature and time,the above indexes of plants showed different changes.Under different conditions,the tolerance of cadmium stress to cadmium stress had different thresholds.When the mass concentration was 0.5 mg·L-1,the CAT,POD activity and MDA content decreased first and then increased.While the chlorophyll content and root activity increased first and then they showed a downward trend with the increase of time.This phenomenon indicated that the protective mechanism of cells of Eichornia crassipes plants under low concentration of cadmium stress could resist the damage of cadmium ions to plants.High concentration of cadmium stress could cause toxic effects on purple root water hyacinth,causing serious damage to plant growth and development.The combined stress of low temperature and cadmium had synergistic effect on the growth of purple root water hyacinth.At the same time,the combined damage to the purple root water hyacinth was greater than the single stress;low temperature stress could affect the tolerance of cadmium stress in purple root water hyacinth.And the lower the temperature was,the lower tolerance of purple root water hyacinth to cadmium stress was indicated.
