INTERACTIVE EFFECT OF MELOIDOGYNE JAVANICA AND OZONE ON LEAF PIGMENT, NITROGEN AND PROTEIN CONTENT OF PEA

Abstract

The effect of Meloidogyne javanica and ozone (0.1 and 0.2 ppm) on leaf pigment and nitrogen and protein content of seeds in pea was studied under conditions of artificial exposure in a glasshouse. M. javanica or ozone alone caused significant reductions in all the considered parameters. However, together they exhibited a synergistic interaction which resulted in greater quantitative reduction in chlorophyll, carotenoid and nitrogen content of leaves and protein content of seeds.
