Micrografting: A in-vitro technique for sustainable horticulture production and its applications

A variety of plant species, especially woody plant species, can be micropropagated using the crucial technique of in vitro micrografting. In vitro micrografting has developed over the past few decades into a method to speed up shoot recovery and adaptation of horticultural species cultivated in vitro. This review analyses studies on horticultural crops that address the development of in vitro micrografting, factors influencing its performance, and the contribution of micrografting applications to the field of micropropagation. The potential application of this technique is based on the significant contributions that micrografting makes to the recovery of vigour and rooting competence, the promotion of shoot recovery following somatic embryogenesis and organogenesis, and the facilitation of shoot regrowth following cryopreservation. This technique facilitates the genetic engineering and preservation of horticultural crops are highlighted.
