Abstract: | The present study illustrates the effect of 24-epibrassinolide (24-EBL) on morphological and biochemical parameters in radish
(Raphanus sativus L.) seedlings grown under nickel (Ni) ion stress. The radish seeds pre-soaked in different concentrations of 24-EBL were
sown in petridishes containing various concentrations of heavy metal (Ni).Observations were made on root/shoot length, fresh
biomass, activities of antioxidant enzymes (ascorbate peroxidase, superoxide dismutase, catalase, monodehydroascorbate reductase,
dehydroascorbate reductase, guaiacol peroxidase and glutathione reductase), lipid peroxidation, proline and protein content
in 7-day-old Ni-stressed radish seedlings. Results indicate that seeds presoaked with 24-EBL reduced the impact of Ni-stress
which was evident by assessing the morphological parameters, protein content and antioxidant enzyme activities. It was also
observed that 24-EBL reduced the toxicity of heavy metal by influencing proline and malondialdehyde (MDA) content. The present
study lays a foundation for understanding the role of 24-EBL in heavy metal stress amelioration, particularly in food crop.
Analysis of behaviour of antioxidant enzymes will play a critical role in understanding the stress networking, further filling
the knowledge gap on the subject. |
