- Abstract
- The characterisation of plant responses to
metal exposure represents a basic step to select a plant
species for phytoremediation. In the present work, 3-
week-old Amaranthus paniculatus L. plants were subjected
to nickel chloride concentrations of 0 (control),
25, 50, 100 and 150 ?M in hydroponic solution for
1 week to evaluate morphophysiological responses,
such as biomass production and partitioning, nickel
accumulation in plants and nickel removal ability from
the polluted solutions. The results showed a progressive
decrease in plant organ dry mass with the enhancement
of nickel (Ni) concentration in the solution, suggesting a
good metal tolerance at 25 ?M Ni and a marked sensitivity
at 150 ?M Ni. The modification of biomass partitioning
was particularly appreciated in leaves,
analysing the organ mass ratio, the total leaf area and
the specific leaf area. Amaranthus plants accumulated a
significant amount of Ni in roots exposed to the highest
Ni concentrations, while lower metal contents were
observed in the aerial organs. The Ni uptake ratio was
progressively reduced in plants exposed to increased Ni
concentrations. The metal translocation from root to
shoots, appreciated by the Ni translocation index,
showed a far lower value in Ni-exposed plants than in
controls. Moreover, by measuring the daily Ni content
of the solutions, a lower Ni removal ability was found in
Amaranthus plants at increasing Ni concentrations.
Remarkably, plants exposed to 25 ?M Ni succeeded in
removing almost 60 % of the initial Ni content of the
solution showing no stress symptoms. The potential of
A. paniculatus for phytoremediation was discussed. (literal)
