Interaction effects between arbuscular mycorrhizal fungi and root-knot nematode Meloidogyne incognita on tomato
Abstract
Five different arbuscular mycorrhizal (AM) fungi (Glomus fasciculatum, G. macrocarpum, Gigaspora margarita, Acaulospora laevis and Sclerocystis dussii) were evaluated for their ability to mitigate damage caused by Meloidogyne incognita on tomato. G. fasciculatum was most efficient in promoting plant growth in presence of nematodes. However, G. macrocarpum and G. margarita were also efficient. Plant biomass and phosphorus uptake were highest in these treatments. The development of nematode stages in the roots and the nematode numbers in soil were differently suppressed by AM fungi, with most pronounced effect with G. fasciculatum, comparatively less with G. macrocarpum and G. margarita. A. laevis and S. dussii did not show any effect.
