Abstract
Parthenium hysterophorus L. is an invasive alien species of natural and
agroecosystems. It causes biodiversity loss in the former and yield loss in the later.
Successful eradication of P. hysterophorus is still a distant dream. We argue that the
possibilities to exploit this species for material production and services should be
explored. Present study evaluates this species for phytoremediation of chromium (Cr)
and nickel (Ni). P. hysterophorus plants were exposed to four concentrations of
chromium (CN10, CN15, CN30 and CN40) and nickel (NN10, NN20, NN40 and
NN50). The low concentrations of Cr (CN10) and Ni (NN10 and NN20) enhanced all
the growth parameters studied. Shoot accumulation of Ni exceeded the root
accumulation (TF<1) while TF>1 was noted for Cr. P. hysterophorus accumulates
both heavy metals as evident from high biological concentration factor (BCF) and
biological accumulation coefficient (BAC). Hence P. hysterophorus can act as
phytoremediator of Ni and Cr.
