Root-Knot Nematodes and the Process of Ageing in Plants

Authors

Abstract

Infection of plants by root-knot nematodes is often accompanied by physiological changes characteristic of ageing. Ultra-low tissue luminescence of infected plants indicated oxidation of cell-membrane lipids. Cells with membranes subjected to oxidation lose some of their capacity for water retention. Treating tomato and radish with lidocaine hydrochloride, an inhibitor of lipid oxidation, retarded above-ground symptoms of root-knot nematode infection and of ageing. Key Words: Meloidogyne hapla, Meloidogyne incognita, antioxidant, lidocaine, luminescence.
