Phoenix (plant) thin layer of fruit pulp. The central soft part of the stem of "P. rupicola, P. acaulis," and "P. humilis" is a rich source of starch. Palms are felled to extract this central ‘pith’ which is dried, powdered, stored and used for preparation of bread by Indian natives. The "P. canariensis" sap is cooked to a sweet, thick syrup. "P. sylvestris" Roxb. is widely used in India as a source of sugar. The sugary sap from some African palms yields country liquor on fermentation (palm wine). While "P. dactylifera" is grown for its edible dates, the Canary Island date palm
Fruit tree pollination a pollinator tree. Working from an old Spanish variety, "Tuono", researchers in 2008 started making available new self-fertile varieties that more closely match the qualities of the popular "Nonpareil" almond—including varieties "Lone Star" and "Independence". While self-fertile trees do not require pollen from a second tree variety for fruit / nut set, they still depend upon insect pollination for good production. Almond growers with self-fertile almonds report excellent nut set with half (or less) the number of bees in the field. Like apples, pears are self-incompatible and need to attract insects in order to be pollinated and produce fruit. One
