Summary

Artocarpus mariannensis is a large, fast-growing, tropical tree up to 20 m high with a rounded, spreading crown and broadly oval leaves. All parts of the plants are used medicinally. The latex derived from the plant is diluted and taken internally for treatment against diarrhoea, stomach pain, and dysentery. It can be applied externally as well against skin ailments and thrush and other fungal diseases. Further, it can be used as treatment for broken bones and sprain, and as relief from sciatica. Skin ailments can also be treated using crushed leaves and macerated roots of this plant. The sap from the crushed petioles is used against ear infections and sore eyes. Lastly, the bark is used against headaches. The edible fruit has a deep yellow pulp that is sweet. Mature fruits are eaten fresh while immature ones are usually roasted or baked. Seeds are cooked as well. The latex can be used to make chewing gums. Aside from being a medicinal plant and a food source, A. mariannensis provides other purposes like as a trellis for other plants or as an inter-crop. Further, the inner bark can produce fibre that is used in making cordages for fishing. It can also be used as a mosquito-repellent by drying and burning the male flowers of the plant. It is a great agroforestry species for stabilizing and enriching the soil. Other Names: ulu Elihe, Dugdug, Chebiei, Ebiei meduuliou, Dokdok, Maiyah, Mei chocho, Te mai [1b].

The roasted seed has a flavour much like a chestnut[ 354 ]. Cooked sprouted seeds are a delicacy on some atolls[ 303 ]. The seeds are high in protein, carbohydrates, low in fat, and a good source of minerals and vitamins, especially vitamin A[ 303 ]. The large, dark brown, shiny seeds are about 15mm long, with little or no endosperm. There are up to 15 seeds per fruit[ 303 ].

Medicinal Uses

All parts of the plant are used medicinally, especially the latex, leaf tips, and inner bark[ 303 ]. The diluted latex is taken internally to treat diarrhoea, stomach-aches, and dysentery[ 303 ]. Applied externally, the latex is commonly used to treat skin ailments and fungus diseases such as thrush[ 303 ]. It is massaged into the skin to treat broken bones and sprains and is plastered on the spine to relieve sciatica[ 303 ]. The crushed leaves are commonly used as a poultice to treat skin ailments and fungus diseases such as thrush[ 303 ]. The sap from the crushed petioles (leaf stalks) is used to treat ear infections or sore eyes[ 303 ]. The root is astringent and used as a purgative[ 303 ]. When macerated, it is used as a poultice for skin ailments[ 303 ]. The bark is used to treat headaches[ 303 ].

Other Uses

Other uses rating: High (4/5). Agroforestry Uses: The plant naturally occurs on steep ridges, cliffs, and shallow calcareous soils where it acts as a soil stabilizer[ 303 ]. It can be inter-planted with a wide range of fruit and vegetable crops such as yam, banana, coconut, taro, papaya, sugarcane, arrowroot, beach hibiscus, Indian mulberry, citrus, soursop, medicinal plants, aroids, ginger and noni, amongst others[ 303 ]. The leaves provide abundant mulch for the tree and other plants growing beneath the canopy[ 303 ]. It is an ideal tree for home gardens on atolls because of its adaptability to calcareous soils and saline conditions and especially for the beneficial shade it produces. The tree can also be used as a trellis for yam[ 303 ]. Other Uses A sticky white latex is present in all parts of the tree[ 303 ]. It is used as a chewing gum, an adhesive, and to caulk canoes[ 303 ]. A fibre is obtained from the inner bark. It is used to make strong cordage used for fishing[ 303 ]. The inner bark was formerly used to make bark cloth (tapa). Sections of the bark were hammered flat with a wooden mallet onto a wooden surface. The more the bark was beaten, the finer the cloth that was made[ K ]. Dried male flowers can be burned to repel mosquitoes and other flying insects[ 303 ]. The flexible leaves are used to wrap foods for cooking in earth ovens, and as plates[ 303 ]. The wood is light in weight, flexible, easy to work[ 303 ]. It is used to make small canoes, carve into statues, bowls, fishing floats, and other objects, although the wood needs to be protected from direct sunlight[ 303 ]. Trunks of larger trees are used to make dug-out canoes[ 354 ]. The wood is fast burning, but generally older, less productive trees are used for fuel[ 303 ].

Cultivation details

Management: Standard;  Regional Crop;  Staple Crop: Balanced carb.

A plant of lowland tropical areas, usually found at elevations below 150 metres[ 303 ]. It grows best in areas where the mean maximum temperature of hottest month is 29 - 31c and of the coolest month 16 - 18c. It prefers a mean annual rainfall in the range 1,300 - 3,800mm[ 303 ]. Older plants grow well in a sunny position, but young plants require some shade, with seedlings requiring 20 - 50% shade[ 303 ]. Prefers a light, well drained, and volcanic and shallow calcareous soil, either sandy, sandy loams or loams, with a pH in the range 6.1 - 7.4[ 303 ]. The plant tolerates saline and coralline soils and atolls[ 303 ]. Established plants can tolerate drought for a few months[ 303 ]. Trees can begin fruiting when about 5 years old[ 303 ]. It can yield 50kg of fruit per tree per year. A fruit can weigh about 500g. The flowers require cross-pollination for seeds to be produced, but unpollinated flowers will still produce a fruit[ 303 ]. The tree is shallow-rooted[ 303 ].
