The Inhibition of Bean (Vigna radiata) Plant Metabolism by Cadmium Metal
II: The Inhibition of Mineral Acquisition in Heavy Metal Contaminated Environment
Abstract:
In this study the effect of (Cadmium) Cd metal on essential mineral ions
nutrients of Vigna radiata (bean) plants has been examined. Results have
been explained in relation with soil microorganism and acquisition of mineral
nutrients like Na, K, Ca, Mg, Mn, PO4 and Fe. Thus environments, which
are polluted by toxic metal can pose a challenge to nutrients acquisition by plant
roots and threaten to survival of many beneficial microbes including the roots
of plants themselves. Analysis of roots showed that Rhizobium species were
effected by heavy metal Cd which results in the inhibition of nodulation of leguminous
plant and decreases in the acquisition of mineral ions concentration at all concentration
of cadmium.
