Abstract:
The concentrations of eight plant nutrient elements (N, P, K, Fe, Mn, Cu, and Zn) were measured in the leaves and roots of the emergent macrophytes, Euryale ferox (Salisb.), and Trapa bispinosa (Roxb.) taken from experimental farm ponds of ICAR-RCER, Research Centre for Makhana, Darbhanga. E. ferox leaves showed higher concentrations of C, N, P, and Zn than roots while the roots exhibited significantly higher concentrations of K, Fe, Mn and Cu. T. bispinosa roots also contained higher concentrations of Fe, Mn and Cu than its leaves, but the differences were significant only for P. Fe was the only nutrient that showed the highest concentrations in roots of both the plants. T. bispinosa roots had higher values of N, P, K, Cu and Zn than E. ferox roots. By contrast, C, Fe and Mn concentrations were higher in E. ferox leaves than in T. bispinosa leaves. E. ferox and T. bispinosa showed high capability to accumulate Fe and Mn in their leaves as well as in roots, appeared a good biomagnification plants.
