Abstract
Cadmium (Cd) is a heavy metal that is uptaken by plants, accumulates in edible parts of plants and negatively impacts human health. This study was conducted to investigate the uptake and accumulation of Cd in different parts of reddish. The experimental design was a factorial with complete block design using three levels of Cd (0, 30 and 60 mgkg-1) and two dates of harvesting (commercial maturity and one week after commercial maturity, called 1st and 2nd dates of harvesting) with three replications. The experiment was carried out using pots which were inserted at research farm of Shahid Chamran University of Ahwaz. Results indicated Cd accumulation in different parts of reddish as the Cd concentration rates increased. The highest Cd accumulation was in the roots (79.35 mg kg-1) at the 2nd date of harvesting. The maximum Cd accumulated in hypocotyls (36.0 mg kg-1) at the 1st date of harvesting, hypocotyls skin (45.0 mg kg-1) at the 1st date of harvesting, and leaves (95.4 mg kg-1) at the 2nd date of harvesting when 60 mg kg-1 of Cd was applied. The results also showed that Cd treatment maximizes Cd at the 1st date of harvesting and increases over the second time of harvesting in reddish organs. The order of Cd accumulation from the highest to the lowest concentration was leaves, roots, petioles, hypocotyls skin and hypocotyls.
