The effects of 28-homobrassinolide (HBL) on nickel uptake, protein content and activities of antioxidative enzymes (guaiacol peroxidase, catalase, glutathione reductase, ascorbate peroxidase and superoxide dismutase) were determined in the seedlings of Brassica juncea. The seeds were treated with different concentrations (0, 0.01, 1 and 100 nM) of HBL for 8 h and then sown in the Petri plates containing various concentrations (0, 25, 50 and 100 mg/cubic dm) of Ni. After 7 d, observations were made on shoot and root length, Ni uptake, protein content and activities of antioxidative enzymes. The growth of seedlings was inhibited by Ni, however, less after HBL pre-treatment. The protein content and antioxidative enzyme activities were also increased by HBL treatment.
