Abstract

A greenhouse investigation was conducted to study the influence of the arbuscular mycorrhizal (AM) fungus Glomus mosseae and the plant growth-promoting rhizomicroorganisms (PGPRs) Bacillus coagulans and Trichoderma harzianum on the growth and nutrition of micropropagated Ficus benjamina plantlets. The AM fungus was inoculated either singly or in combination with the PGPRs. Plants showed maximum plant height, biomass, P content, mycorrhizal root colonization, spore numbers and populations of T. harzianum and B. coagulans in root zone soil when all the three organisms were inoculated together. Thus, when G. mosseae co-inoculated with PGPRs enhances growth and nutrition of Ficus benjamina. T. harzianum and B. coagulans are thus designated as mycorrhizal helper organisms.
