Antioxidant Enzyme Activities of the Leaves of Groundnut (Arachis hypogeae L.) Planted on Crude Oil-Contaminated Soil

ABSTRACT: Antioxidant enzyme activity of groundnut leaves planted in crude oil contaminated soil was evaluated. 1.5 kg of soil each was placed in black polythene bags. They were divided into four groups (A-D) of five bags each. Each group was treated with different concentrations of crude oil (0 ml, 5 ml, 10 ml and 15 ml per 1.5 kg soil respectively). five seeds of Arachis hypogaea were planted in each bag.
