Artocarpus integer

Artocarpus integer, commonly known as chempedak or cempedak, is a species of tree in the family Moraceae, in the same genus as breadfruit and jackfruit. It is native to Southeast Asia. Cempedak is an important crop in Malaysia and is also popularly cultivated in southern Thailand and parts of Indonesia, and has the potential to be utilized in other areas. It is currently limited in range to Southeast Asia, with some trees in Australia and Hawaii.

Cempedak trees are large, evergreen trees. They can grow to a height of 20 m, although most reach only a dozen meters. The trees are monoecious, with male and female flowers growing on the same tree. There are many varieties, although few are named. The vigorously growing tree can bear heavy crops of fruit once or twice a year.[citation needed]

The syncarp may be cylindrical to spherical in shape, and ranges from 10 to 15 cm across and 20 to 35 cm in length. The thin and leathery skin is greenish, yellowish to brownish in color, and patterned with pentagons that are either raised protuberances or flat eye facets.[citation needed]

Fleshy, edible arils surround the large seeds in a thick layer. The arils are edible raw, or they can be prepared in a number of ways. They are yellowish-white to orange in color, sweet and fragrant, soft, slippery and slimy on the tongue and slightly fibrous. Ripe cempedak fruit has a pungent smell that has been described as harsh and penetrating like that of durian. The taste of the fruit is similar to the related jackfruit and breadfruit with a hint of durian. The seeds, which are also edible, are flattened spheres or elongated, about 2–3 cm in length.[citation needed]

Cempedak is similar to jackfruit in many ways, but is smaller than jackfruit and the peduncle is thinner. The male inflorescence of cempedak is pale green to yellow compared to the dark green of jackfruit. The cempedak flesh is darker yellow and juicier when ripe.

Cempedak trees are normally planted in non-eroded and well-drained soils, although they can tolerate temporary flooding. They can be grown from sea level to 1,200 metres (3,900 ft) altitude at temperatures between 13–47 °C (55–117 °F) and with annual rainfall of 1,250–2,500 millimetres (49–98 in).[citation needed]

In the Malay Archipelago, cempedak is usually cultivated with other fruit trees in mixed orchard systems of small farmers and occasionally in large fruit plantations. The trees are normally propagated by bud-grafting to maintain desired genetic traits. Plants are also propagated by seed, but the seeds spoil quickly after removal from the fruit, so they must be planted immediately after cleaning.

Trees begin to bear fruit at 3–6 years for trees planted by seed and at 2–4 years for clonal trees. Blossoms are common from February to April and then again in August to October in southern Malaysia, as opposed to in western Java, where cempedak tend to flower in July and August. From flowering to ripening fruit takes about 2–4 months.
