Cd胁迫下绿豆幼苗根部对K·Ca·Mg含量的影响
Effect of Cd Stress on Concentration of K, Ca and Mg in Root of Phaseolus raditus L.Seedlings
摘要
Abstract
[Objective] The aim was to study the metabolism of K, Ca and Mg in the root of Phaseolus raditus L. seedlings under Cd stress. [ Method] Cd contamination was simulated with 1 祄ol/L Cd2+, and the content of K, Ca and Mg were detected by the flame atomic absorption spectrometry (FAAS). [ Result] The concentration of Mg in root reduced, and the concentration of K firstly increased and then declined,the concentration of Ca improved under Cd contamination. [ Conclusion] Cd produces an indirect impact on the growth of Phaseolus raditus L. seedlings.关键词
