| Abstract:
Fruit trees, including almond, are complex individuals made up of the symbiotic scion/rootstock association. These two components interact mutually, depending on their genotype and environmental influence. Rootstock characteristics, however, have been less studied than those of the scion; consequently, rootstock selection has been somewhat neglected and traditionally almond seedlings from unknown origin have been used. During the last fifty years, many studies and trials have been conducted on different types of rootstocks for almond. These studies described many of the problems that arise when traditional rootstocks are used. In this study we review the desirable characteristics of an ideal almond rootstock, stressing the features related to nursery management (propagation and on line behaviour), graft compatibility, orchard management (tree growth and size, agronomical behaviour in irrigated and non-irrigated conditions, plant anchorage, suckering), resistance to abiotic stress and biotic agents, and the sanitary status of the mother plants used for propagation. | |
