Initiation and development of AR seedlings is a crucial stage during the vegetative propagation of commercially important plant seedlings. Moreover, initiation of root primordia from callus or explants is crucial in plant transformation. Many medicinal plants and horticulture crops are vegetatively propagated with stem cuttings and it depends on initiation and development of AR. Commercially available plant root inducing hormones such as IAA, IBA or other auxin derivatives are being used in plant tissue culture medium or in other controlled environments to initiate AR.
