| Abstract:
The cultivar ‘Moniqui’, one of the most appreciated apricots, needs the use of rootstocks other than P. armeniaca in order to resolve the problems of its soil adaptation. In the selection of rootstocks for ‘Moniqui’, the study of incompatibility is an essential criterion, and it is necessary to detect this problem at an early stage of development. For this reason, the purpose of this research was the study of cell adhesion and cellular death at the graft interface and their involvement in graft incompatibility responses during the first month after grafting. These preliminary results have shown the involvement of pectins and cellular death, in the early responses to grafting, in the development of cohesion between the stock and scion during graft ontogeny and the consequences for the future graft response. | |
