Abstract
The present work was undertaken to study the effects of 28-homobrassinolide on growth, stress markers, antioxidative enzyme [superoxide dismutase (EC 1.15.1.1), guaiacol peroxidase (EC 1.11.1.7), catalase (EC 1.11.1.6) ] activities and protein content in 10 days old seedlings of Brassica juncea L. treated with different degrees (4°C, 44°C) of temperature. 28-homobrassinolide at 10-9 M concentration lowered temperature stress. Different degrees of temperature treatment alone decreased the enzyme activities and protein concentration of seedlings. However, pre-sowing treatments of 28-homobrassinolide lowered the temperature stress and enhanced the contents of MDA and proline, activities of enzymes and protein concentration of seedlings.
