چکیده

The effect of 24-epibrassinolide (24-epiBL) on seedling growth, metal uptake and accumulation were investigated in seedlings of Brassica juncea L. cv. PBR 91. Seeds of B. juncea treated with different concentrations (0, 10-7, 10-9 and 10-11 M) of 24-epiBL for 8 h were subjected to various concentrations (0, 25, 50 and 100 mg l-1) of heavy metals (Zn, Mn, Co and Ni). Seedling growth was improved by 24-epiBL treatments under heavy metal stress. In addition, 24-epiBL applied at concentrations of 10-9 and 10-11 M blocked heavy metal uptake and accumulation.

Heavy metal toxicity: Effect on plant growth, biochemical parameters and metal accumulation by Brassica juncea L.

Plant growth, pigment concentration, biochemical parameters and uptake of heavy metals were determined for Brassica juncea L. in response to cadmium and lead stress. The plant exhibited a decline in growth, chlorophyll content and carotenoids with Cd and Pb but Cd was found to be more detrimental than Pb treatment in B. juncea. The protein content was decreased by Cd (900 μM) to 95% and 44% by ...

The present experiment was designed to assess the effects of seed soaking with 24-epibrassinolide (EBR) on the physiology of Brassica juncea L. seedlings grown under imidacloprid (IMI) toxicity. Application of EBR increased the length of seedlings, dry weight, and pigment contents, polyphenols, total phenols, and organic acids under IMI toxicity. The expression of genes coding key enzymes of pi...
