Cadmium uptake by some Chenopodium spp. as model of phytoremediation technology

الملخص EN

Cadmium (Cd) is extremely toxic heavy metal which adversely affects the growth of plants.

Phytoextraction one from among of phytoremediation technology methods has proven to remediate media contaminated with heavy metals.

The objective of this research is find out whether Chenopodium species (Ch.

ambrosoidae, Ch.

album and Ch.

quinoa) can be used as a Cd hyperaccumulator from through study effects of Cd on growth of species seedlings.

Therefore, three Cd concentrations (10, 20 and 30 ppm) with addition to control have conducted to archive aim of study.

Different parameters have tested in present study include growth, physiological and biochemical parameters of growth seedlings stage.

Results indicate that the inhibitory effect had observed on all growth, physiological and biochemical traits of early growth seedlings stage.

Chenopodium species have many tolerance mechanisms against Cd stress such as membrane stability, stability pigments and activity of antioxidant enzymes under Cd treatments.

Data indicated that Ch.

quinoa get the better of another two species in Cd uptake and total tolerance index of Cd, so, we demonstrated that Ch.

quinoa suitable for phytoextraction
