Description The aim of the present study was to
investigate the capability of Sunflower (Helianthus
annuus L.) to tolerate and accumulate high amount of
lead (Pb) and propose it for soil phytoremediation. To
this regard, plants were grown in hydroponics and
treated with different Pb concentrations (10 to
160 μM) and a fixed concentration (500 μM) EDTA
(ethylene diamine tetra acetic acid) for 14 and 28 days
(d). Effects on total biomass production, photosynthetic
pigments and protein contents as well as the
quantities of non protein thiols (NP-SH), glutathione
(GSH), phytochelatins (PCs) and activity of glutathione
reductase (GR) were estimated. Results revealed
that roots (575 μg g−1 DW) and shoots (135 μg g−1
DW) accumulated Pb after 28 d of exposure,
however, addition of EDTA enhanced the Pb accumulation
in roots (645 μg g−1 DW) and shoots
(255 μg g−1 DW ). Exposure of Pb (28 d) registered
a significant (P
