Phoenix (plant) hybridisation and cross-pollination. Several natural hybrids were hence obtained: "P. dactylifera X. P. sylvestris "(India)," P. dactylifera × P. canariensis" (Morocco, Algeria and Israel), and " P. dactylifera × P. reclinata "(Senegal). "Phoenix" species are used as food plants by the larvae of some Lepidoptera species, including "Paysandisia archon" and the "Batrachedra" species "B. amydraula" (recorded on "P. dactylifera"), "B. arenosella" and "B. isochtha" (feeds exclusively on "Phoenix" spp.). The fruit of "P. dactylifera", the date of commerce, is large with a thick layer of fruit pulp, edible, very sweet and rich in sugar; the other species have only a
Fruit tree propagation fruit cultivars vegetatively in order to ensure reliability. This involves taking a cutting (or scion) of wood from a desirable parent tree which is then grown on to produce a new plant or "clone" of the original. In effect this means that the original Bramley apple tree, for example, was a successful variety grown from a pip, but that every Bramley since then has been propagated by taking cuttings of living matter from that tree, or one of its descendants. The simplest method of propagating a tree vegetatively is rooting or taking cuttings. A cutting (usually a piece of stem
