Abstract: | The present study was conducted to study the effect of 24-epibrassinolide (EBL) on changes of plant growth, net photosynthetic
rate, carbonic anhydrase (E.C. 4.2.1.1) and nitrate reductase (E.C.1.6.6.1) activities in the leaves of Raphanus sativus L. under the influence of cadmium (Cd) stress. Cd reduced plant growth, photosynthetic pigment levels, net photosynthetic
rate and the activities of carbonic anhydrase and nitrate reductase. However seed application of EBL reduced the toxic effect
of Cd on plant growth, pigment content, photosynthesis and enzyme activities. The studies clearly demonstrated the ameliorating
effect of 24-epibrassinolide in mitigating the toxicity of Cd in plants. |
