Differential Response of Brassica Cultivars to Potentially Toxic Elements and Their Distribution in Different Plant Parts Irrigated with Metal-Contaminated Water

The increasing concentration of potentially toxic elements (PTEs) in agricultural soils has greatly disturbed the quality and productivity soils. In this study, we investigated uptake distribution cadmium (Cd), lead (Pb), nickel (Ni) by two Brassica cultivars (Khanpur raya Sandal canola) grown on soil irrigated with metal-contaminated water. Distilled water was spiked salts to prepare irrigation various levels metals (Ni application at 90, Cd 20, Pb 500, Ni + 20 90 500 mg L?1). These treatments were compared without addition any salt. results indicated that control treatment, metal concentrations decreased shoot weight (44.25%, 29.03%), root length (33.33%, 12.74%), (19.73%, 11.06%) Khanpur canola, respectively. Compared contaminated photosynthesis rate (98.42%, 99.34%), chlorophyll content (18.27%, 13.73%), respiration (7.97%, 6.47%), transpiration (9.90%, 33.33%) both varieties, Notably, (0.01 0.003), 0.012), (0.03 0.05%) seeds increased, as well respectively, controls. Furthermore, PTE accumulation different components recorded, order > seed. It observed brassica differed significantly their response growth PTEs edible parts. concluded did not exhibit a decline due prevented translocation towards parts canola thus can be safely receiving PTE-contaminated
