Description

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 .

Cultivation

Management: Standard Regional Crop Staple Crop: Balanced carb Staple Crop: Basic Starch
A plant of lowland tropical areas, usually found at elevations below 150 metres. 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. Older plants grow well in a sunny position, but young plants require some shade, with seedlings requiring 20 - 50% shade.

The plant tolerates saline and coralline soils and atolls. Established plants can tolerate drought for a few months. Trees can begin fruiting when about 5 years old. 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. The tree is shallow-rooted.
