ABSTRACT
A pot experiment was conducted to study the effects of priming and foliar application of 24-epibrassinolide (24-EBL) at different concentrations (0, 10-5, 10-7 and 10-9 M) on physiological parameters of black gram plants subjected to salt stress (0, 8, 12 and 16 dS/m). Results revealed that salinity drastically reduced photosynthetic pigments and protein content over control. However, application of 24-EBL was found to improve the photosynthetic pigments and leaf protein of salt-treated plants. The study also revealed that foliar application was more effective than seed priming in lowering salinity induced malondialdehyde (MDA) content and in alleviating salinity stress in black gram plants.
Key words : 24-epibrassinolide, lipid peroxidation, photosynthetic pigments, protein, salt stress
