Effect of Meloidogyne javanica on seedling growth of su-babool (Leucaena leucocephala)
AbstractSu-babool, Leucaena leucocephala (Lam.) De Wit., a native Mexican plant, is commonly grown as tree component of agro-forestry systems in India. Azmi and Ahmad (1980) reported that soils supporting these systems harbour large populations of plant parasitic nematodes. Both field plantations and nurseries of su-babool are infested with root-lesion (Azmi, 1984) and root-knot (Azmi, 1985, 1986) nematodes. This paper reports the effect of Meloidogyne javanica (Treub) Chitw on the growth of su-babool seedlings and development of galls and egg masses on the roots in greenhouse conditions. The results demonstrated that M. javanica is pathogenic to su-babool and causes stunting and defoliation of the shoot and galling of the roots.
