Antioxidant system status of cucumber plants under pesticides treatment

Abstract

A plants’ physiology maybe affected by various pesticides through the activation or inactivation of different biochemical pathways in target and non-target plants. In response to pesticides as xenobiotics, plants activate their antioxidant defense systems through both enzymatic and non-enzymatic pathways. In this study, two of the most common pesticides used to control cucumber whiteflies, imidacloprid and dichlorvos were sprayed on cucumber seedlings. Treatment with both pesticides significantly increased the activity of superoxide dismutase, catalase, ascorbate peroxidase, guaiacol peroxide, and phenylalanine ammonia-lyase. Moreover, total protein, proline, total soluble carbohydrates, and..
