Description
''Bactris gasipaes'', like most sea-island palms, grows erect, with a single slender stem or, more often, several stems that are up to eight inches (20 cm) thick, in a cluster; generally armed with stiff, black spines in circular rows from the base to the summit. There are occasional specimens with only a few spines. It can typically grow to or taller. The trunk is composed of a hard outer ring of black fibers embedded in a lighter tan or light brown colored body. Fibers are more densely packed toward the outside of the tree trunk, becoming more and more sparse toward the center of the tree. The center core of the tree is soft and contains none of the darker vascular bundles that give the wood its characteristic look and hardness. The

) of the fruit can be red, yellow, or orange when the fruit is ripe, depending on the variety of the palm.
Ecology
The peach palm grows wild in well-drained soils with various physical and chemical conditions, including acid and poor soils, since it is assisted by its association with mycorrhizas. It is grown in climates with precipitations between 2 000 mm and 5 000 mm and annual mean temperatures exceeding 24 °C. The recommended altitude for commercial cultivation ranges from 0 to 900 m asl. Peach palm is occasionally found at higher altitudes of up to 1800m asl, as the case in Colombia's Cauca region El Tambo.
Peach palm can be considered the most important domesticated palm species of the

s.
Wild and cultivated peach palm populations are genetically very diverse and could offer useful traits for breeding. Genetically the peach palm can be divided into (a) two western populations including Central America, the Andean valleys of Colombia and Venezuela and the pacific lowlands of Colombia and Ecuador; and (b) two eastern populations including the upper and the eastern Amazon. In general the western populations have harder stems, more abundant and stronger spines, larger leaves and more solid rooting in their juvenile phase.
Peach palm is a predominantly outcrossing species, though self-fertilization has also been observed. Pollination is carried out mainly by insects, especially by small curculionid beetles over distances between 100 and 500 m. Wind and gravity can also function as pollen vectors. Since peach palm is a long-lived perennial and predominantly outcrossing species the genetic diversity of the populations is high. Though no definite studies have been conducted on seed dispersal of peach palms, it is probably restricted locally to dispersal by birds and seed-gathering mammals. Seeds may only be occasionally dispersed by water of greater distances. The gene flow of outcrossing tree species with such scattered distribution may be restricted and could result in genetically distinct, isolated subpopulations with small effective population sizes.
In contrast to the cultivated peach palm, wild populations are threatened by deforestation, driven mainly by

and the transition of forest to savannah. Many populations are now isolated by increasing forest fragmentation, which will lead to decreased reproduction via inbreeding depression and eventual extinction even without complete deforestation. Their natural distribution is not yet well defined. Wild peach palm trees can be found in disturbed ecosystems, on river banks and in primary forest gaps. They often occur in isolation or at low densities.

Besides the fruits and seeds for human consumption, the pre-Columbian uses of the tree included the roots as medicine. The timber is exceptionally dense and strong; it had many uses. It is a durable material for bows, arrows, fishing poles, harpoons and building material, the spines for needles and the leaves for thatch and basketry. Though first used by humans for wood, it was likely fully domesticated for its starchy and oily fruits, of which the

Agriculture
Peach palm has a rapid juvenile growth (1.5 – 2 m per year) and a moderate light interception if the plant is spaced appropriately. Therefore, it is suitable for agroforestry.Clement CR (1989) The potential use of the pejibaye palm in agroforestry systems. Agrofor Syst 7:201–212 In commercial plantations, peach palm is found in agroforestry systems with coffee and banana in Costa Rica. In several countries in Central and South America, it is found in combination with pineapple, papaya, passion fruit, maize, cassava and cacao. Fruit production starts between three and five years after planting and production lasts then for 50 to 75 years. The plant reaches its full productivity after about seven years.

requirements of ''Bactris gasipaes'' are dependent on the nutrient status of the soil and are usually adapted from heart of palm or from other palm fruit production. Phosphorus is considered the most limiting nutrient and yield is driven by phosphorus and magnesium rather than by nitrogen.
