Summary

Peach Palm or Bactris gasipaes is a tropical tall, slender palm that grows up to 24 m in height. It is native to South and Central America. Thorns are present on the trunk and suckers are formed at the base. Seed oil is used medicinally as a rub for relief from rheumatic pains. It is also edible and is used for cooking. The ovoid, yellow to orange fruit is highly nutritious. It is cooked or ground into flour and used in baking. The seed is edible as well - consumed as a nut or made into a meal to flavour drinks. The apical bud is cooked as a vegetable. The pinnate leaves are used as a thatch and as a source of green dye for fabrics. Plant spines are used as needles in tattooing. The roots have vermicidal properties. Fibre used in paper-making can be obtained from the whole plant. The wood is used in construction. Peach palm is grown from seeds or suckers.

Edible Uses

Edible portion: Fruit, Flower shoots, Cabbage, Palm heart, Vegetable. Fruit - cooked[ 297 ]. An acquired taste, mealy and nutty in flavour[ 200 ]. The flavour is variable, ranging from bland to strong[ 303 ]. Inedible raw, it is boiled in salt water for 30 - 60 minutes, when it becomes floury-textured, oily and pleasant tasting with good nutritious qualities[ 297 , 303 ]. The fruit is always cooked, because of the presence of an alkaloid, pupunhadine[ 303 ]. The fruit is highly nutritious, being very rich in carbohydrate and protein[ 200 ]. The fruits are also ground into a flour for baking bread, cakes etc[ 297 ]. The ovoid fruit is about 6cm long[ 200 ]. The fruit palm is an energy-rich source of carbohydrates and oil; the pulp contains all the essential amino acids and is an excellent source of quality protein[ 303 ]. The mesocarp is rich in beta-carotene[ 303 ]. It is regarded as probably the most nutritionally balanced of tropical fruits; has twice the protein content of the banana and can produce more carbohydrate per ha than maize[ 324 ]. An edible oil is obtained from the seed[ 301 ]. It is called oil of macanilla[ 301 ]. The mesocarp oil has a relatively high proportion of unsaturated fatty acids, notably oleic acid, and contains no cholesterol[ 303 ]. It is used for cooking[ 303 ]. Seed - eaten raw or made into a meal to flavour drinks[ 301 ]. Consumed as nuts[ 303 ]. A salt substitute is made by cooking the spadix[ 301 ]. The cooked male flowers are used as a condiment[ 303 ]. The apical bud is cooked and eaten as a vegetable[ 301 , 763 ]. A delicacy, in some areas it is eaten as a salad[ 303 ]. Fresh, dried and canned palmito is being marketed for use in salads, soups and fillings and as roasted chips[ 303 ]. Eating the bud effectively kills the trunk since it is unable to produce side shoots[ 301 ]. Some plants in this species form multi-trunks and so harvesting the apical bud will only kill one stem, not the plant[ K ]. An important food in South America.

Medicinal Uses

The oil from the seeds is used as a rub to ease rheumatic pains[ 739 ]. The fruit are high in Vitamin A. The red variety has 2.76 mg of carotene while the yellow variety has 0.835 mg.

Other Uses

Other uses rating: High (4/5). Other Uses An oil is obtained from the seed. This species may turn out to be a better economic option than most other American oil palms. Oil levels of up to 62% of the dry weight have been reported, and there are reports that a large pot of boiling fruit can produce 2-3 kg of oil[ 303 ]. The oil separates easily when the fruits are cooked. As with other palms, it is a potential source of lauric oils. The seed is rich in saturated fatty acids, and could be used to manufacture cosmetics and soap[ 303 ]. The leaves yield thatch for houses and basket materials[ 303 ]. The spines of the plant are used in tattooing[ 46 ]. (Probably as needles[ K ].) The leaves provide a green dye for colouring fabrics[ 303 ]. The roots provide a vermicide[ 303 ]. The whole plant, including the leaf and stem parts, produces a valuable fibre for manufacturing paper[ 303 ]. Cellulose may be produced for cellophane paper and rayon[ 303 ]. Wood - exceptionally hard and strong, it has many uses[ 297 ]. Used in construction[ 46 ]. It is a durable material for bows, arrows, fishing poles, harpoons and carvings[ 303 ]. The Amerindians use the wood for flooring and panelling their houses and also fashion long spines into needles[ 303 ]. In rural Amazonia, the stem is valued for parquet, furniture, carvings and home construction[ 303 ].

Cultivation details

Plants succeed in moist tropical climates with heavy rainfall and poor soils[ 303 ]. They grow in lowland areas below 800 metres, where temperatures never fall below 10?c, the average annual rainfall is 1,500mm or more and the driest month has 25mm or more rain[ 297 , 303 ]. They can withstand relatively hot dry seasons of 3 - 4 months[ 303 ]. Requires a fertile, moist, but well-drained soil, a humid atmosphere and some protection from strong sun[ 200 ]. Seedlings develop very slowly under forest shade conditions, and mature plants require full sunlight for optimal production of flowers, fruits and offshoots[ 303 ]. Plants are most productive when grown on relatively deep, fertile, well-drained soils, clay soils, and highly eroded laterites with 50% aluminium-saturated, acid soils[ 303 ]. Prefers a pH in the range 5 - 6.5, tolerating 4 - 7.5[ 418 ]. The spiny stem of the tree grows rapidly in height, attaining 15 - 20 metres in just 10 years[ 303 ]. Plants begin flowering when 3 - 5 years old, and can produce two fruit crops a year for the next 50 - 75 years[ 303 , 418 ]. Fruit yields may be as high as 10 - 30 tonnes/ha, but are often only about 2 - 3 tonnes/ha[ 418 ]. Yields of 50 - 100 kilos per trunk per year are not unusual[ 418 ]. For palm hearts the yield ranges from 4,000 - 10,000 hearts/ha per year[ 418 ]. Plants sometimes produce just a solitary trunk, at other times they can have several trunks[ 297 ]. Plants produce rings of needle-like spines 5cm long[ 301 ]. This can make harvesting the fruit and buds rather unpleasant. There is at least one named form, called 'Spineless', that is entirely free of these spines[ 301 ]. There are other forms that have seedless fruits[ 46 , 768 ]. A shallow-rooted plant[ 418 ]. Under subsistence conditions palms are often widely spaced but for intensive agriculture it is planted at 400-500 plants/ha for fruit and 3000 to 20 000 plants for heart-of-palm.

Propagation

Seed - pre-soak for 24 hours in warm water and sow in containers. Germination takes 2 months or more[ 297 ]. The seed has a limited viability and needs to be sown as fresh as possible[ 297 ]. Seedlings require about 6 - 9 months in the nursery; planting out should be done when the soil is humid and the potential evapotranspiration rate is low[ 303 ]. Seeds are recalcitrant. They rapidly lose viability when dried and should not be exposed to direct sunlight during germination[ 303 ]. Fresh seed has 45-50% mc, and if this falls below 38-40%, germination is reduced[ 303 ]. Seed is rarely formed in this species[ 297 ]. Division of suckers from a mature palm after it has produced four stems[ 314 ]. Suckers should have produced roots and be 7 to 8 cm in diameter at the base and 1 to 1. 5 metres high[ 314 ]. Mycorrhizae attached to the roots give fast growth rates.
