马络葵对镉的吸收累积特征及对镉胁迫的生理响应
Accumulation Features of Malope trifida to Cadmium and the Physiological Response to Cadmium Stress
摘要
Abstract
[Objective] Accumulation features of Malope trifida to cadmium and the physiological response to cadmium stress were studied to provide theoretical basis for the phytoremediation of cadmium pollution in soil by Malope trifida.[Method] We applied Malope trifida as material, used the sand culture method and designed six different concentrations (0, 0.5, 1.0, 2.0, 3.0 and 4.0 mg/L) of Cd to study the physiological effect of Malope trifida to the stress of heavy metal Cd and its accumulation and operation ability to Cd.[Result] The plant height and the above-ground fresh weight were all higher than CK, the above-ground fresh weight and the root fresh weight were the highest under the concentration of 3.0 mg/L;when the concentration was lower than 1.0 mg/L, the chlorophyll content was easy to synthetize;the contents of soluble sugar were all higher than CK, and the contents of soluble protein were all higher than CK except when the concentration was 0.5 mg/L.[Conclusion] The accumulation of above-ground part and root of Malope trifida to Cd showed the increasing trend with the improvement of Cd concentration, the operation ability of Cd and the tolerance ability to Cd were strong.So that the Malope trifida can be planted in the Cd contaminated soils and can be treated as the pollution remediation plants of heavy metal damage to do further research.关键词
