Narrow decumbent scales of the vertex (19) served as a helpful diagnostic feature to separate Cx.
In spite of the possibility of propagation by grafting, in practice no grafted plants are found in orchards of this fruit because of the slower growth in relation to seminal plants, besides problems of poor stem formation and decumbent branches, a fact that does not motivate the producers to use vegetative propagation in the formation of seedlings in commercial orchards (SACRAMENTO et al., 2007; CARVALHO, 2014).
