| Abstract:
Plant grafting is of considerable importance in the deployment and regional adaptation of elite cultivars, but its range of application is restricted by physiological and biochemical factors that produce incompatible grafts. In this work, in vitro stem unions were examined at early stages of graft union development in order to look into the cellular reponses associated to the (in)compability reaction between apricot/plum grafts. Histological and histochemical aspects during adhesion, callus proliferation, and callus differentiation into new cambium are described. Physiological and histochemical differences were observed in function to the degree of compatibility between the graft partners. | |
