Growth responses of custard apple seedlings to arbuscular mycorrhiza

The present investigation was carried out with a view to study the effect of arbuscular mycorrhizae (AM) viz; Glomus epigaeum, Glomus mosseae and Gigaspora calospora and their combinations on growth parameters of custard apple seedlings. In pot culture experiment, all the three AM fungi either singly or in combinations significantly increased the growth parameters like height of plant, root length, number of leaves, dry weight of shoot and root and mycorrhizal dependency values. The combined inoculation of all the three mycorrhizae was superior over all the inoculation treatments in recording the growth parameters and mycorrhizal dependency values which was followed by combined inoculation of Glomus epigaeum and Glomus mosseae.
