Abstract: This review paper comprehensively discussedthe dynamics of graft union formation in fruit trees. Histological studies confirmed graft union is a continuous process and reliable indicators of graft-compatibility are not visible. Although initiation of scion bud development is signs of graftformation processesbut early callus formation determines subsequent survival of scion prior to cambial and vascular connectivity. Process of graft union formation is similar in most plants with few variations in days to completion. Factors attributed to graft-incompatibility or otherwise have been mentioned whiles research should also target specific tropical plants.

Key words: Graft incompatibility, Graft union formation, Callus formation, Cambium, Vascular connectivity
