The effect of 28-homobrassinolide and 24-epibrassinolide on germination and seedling growth of Sorghum vulgare pers var. CSH-15 R (susceptible to water stress) was studied under water stress. Both the brassinosteroids were very effective in ameliorating the impact of water stress on seed germination and seedling growth. The stress alleviation by brassinosteroids was associated with enhanced levels of soluble proteins and free proline. Brassinosteroids treatment were found to enhance the activity of catalase and reduce the activity of peroxidase.
