%X the present work was undertaken to study the effects of 28-homobrassinolide on growth, zinc metal uptake, antioxidative enzyme [guaiacol peroxidase (ec 1.11.1.7), catalase (ec 1.11.1.6), glutathione reductase (ec 1.6.4.2), ascorbate peroxidase (ec 1.11.1.11), superoxide dismutase (ec 1.15.1.1)] activities and protein content in 7-d-old seedlings of brassica juncea l. treated with zn metal at different concentrations. 28-homobrassinolide at 10-9 m concentration lowered zn uptake and bioconcentration factor. different concentrations of zn-metal treatment alone decreased the enzyme activities and protein concentration of seedlings. however, pre-sowing treatments of 28homobrassinolide lowered the uptake of metal and enhanced the activities of enzymes and protein concentration of seedlings.
