Impact of Arbuscular Mycorrhizal Fungi and Pseudomonas

Gerbera jamesonii is of commercial significance and fifth most used cutflower in the world today. a pot experiment was performed to see the effect ofco-inoculation of arbuscular mycorrhizal fungi (amf) i.e. (glomus mosseaeand acaulospora laevis) with phosphate solubilizing bacteria pseudomonasfluorescens in the presence of different doses of superphosphate (low, medium,high) on growth establishment and flowering response of gerbera. among alltreatments, plants inoculated with mix culture of g. mosseae + a. laevis + p.fluorescens showed best response in terms of greater root length, root biomass,percent root colonization, am spore number, number of flowers, phosphoruscontent and phosphatase activity at lower concentration of superphosphate.moreover, maximum increase in leaf area and shoot biomass was found inplants treated with dual combination of g. mosseae + p. fluorescens at lowerconcentration of superphosphate. this study provides a good scope forcommercially utilizing the efficient strains of am fungi with p. fluorescens inthe establishment and growth improvement of gerbera.
