摘要：
Pesticide toxicity causes oxidative stress to plants by generating reactive oxygen species (ROS). The aim of the present study was to observe the role of 24-epibrassinolide (24-EBL) in protection of Brassica juncea L. plants from oxidative stress caused by imidacloprid (IMI) pesticide. Generation of ROS, activities of antioxidative enzymes and chlorophyll contents were estimated using spectrophotometer, whereas organic acid contents were determined using gas chromatography-mass spectrometry (GC-MS). Statistical analysis of data revealed that 24-EBL significantly decreased ROS contents, accompanied by enhanced levels of shoot biomass, chlorophyll contents, organic acid contents and the activities of antioxidative enzymes in B. juncea plants under IMI toxicity.
