Use of plant growth promoting microorganisms in plant propagation

Microorganisms that can increase plant growth and productivity are termed as plant growth promoting microorganisms. Plant growth promoting microorganisms includes atmospheric N2 fixers, P solubilizers, P mobilizing microorganisms, plant pathogens suppressing microorganisms etc. They are ecofriendly and secretes growth promoting hormones and secondary metabolites which help in mobilizing various micronutrients (Arshad, et al., 1998) which are needed to the plant and to overcome several root borne diseases. Plant propagation is the reproduction or duplication of a plant from mother plant. The cutting, budding, grafting, layering etc. are the important methods of plant propagation.
