Impacts of root knot nematode infestation on metabolites and antioxidant enzymes in Abelmoschus esculentus L. Moench

Abstract

Root knot nematode Meloidogyne incognita is most damaging pest to all vegetable crops and cause losses in yield. Okra crop is widely suffers from root knot nematode Meloidogyne incognita. During infection, plant elicits its defence mechanisms. Defence mechanism includes various cellular activities, metabolic changes to overcome this adverse condition. In present study we study the changes in metabolites content like total protein, total carbohydrates and total protein of infected plant in response to root knot nematode and also study the activities of oxidative enzymes. The results indicated that the infestation of nematode increased the activity of peroxidase, polyphenol oxidase, and Phenylalanine ammonia lyase.
