No one really knows the Jackfruit's place of origin but it is believed to be indigenous to the rainforests of the Western Ghats. 2
The jackfruit is the world's largest tree-borne fruit. The fruit can take on the proportiong of a large watermelon and can weigh more than 80 pounds. Oblong, spiky, oddly retivulated, the fruit dangle from the trunk and major branches on ttout cords. A fruiting tree presents a sensational visual impact. The fruit possesse a fine tropical flavor. The tree is stately and handsome and serves as a beautiful shade tree whan it reaches maturity. It deserves to be planted on a broad scale and its populary as a dooryard tree in Florida is soaring. 8

The jackfruit leaves are evergreen, alternate, glossy, somewhat leathery to 9 in (22.5 cm) long, oval on mature wood, sometimes oblong or deeply lobed on young shoots. All parts contain a sticky, white latex. 2

Short, stout flowering twigs emerge from the trunk and large branches. The tree is monoecious (i.e., male and female flowers on the same tree) with small male flowers held by a thin pedicel. Female flowers are larger than the males and the pedicel is quite thick. 1
Flowers are attached externally to the male and the female fruit.
The jackfruit is a multiple fruit i.e., composed of the coherence of multiple flowers (Fig. 15,16 ). Fruit is moderately large to very large, weighing from 10 to 60 pounds (4.5–27.3 kg). A few cultivars are small fruited, weighing 3 to 10 pounds (1.4–4.5 kg) each. The skin is extremely rough and thick. Fruit skin color is green when immature and green, greenish-yellow to brownish-yellow when ripe. The inside of the fruit contains the edible, sweet, aromatic, crispy, soft, or melting pulp that surrounds each seed. Between the seeds and edible pulp is the inedible “rag". Pulp color varies from amber to yellow, dark yellow, or orange. Seeds are ¾ to 1¼ inches (2 to 3 cm) long, oval; the number per fruit varies from 30 to 500. The time from flowering to fruit maturity ranges from 150 to 180 days. 1

There is limited experience on the performance of jackfruit cultivars under various conditions; however, initial evaluation of a number of cultivars has been completed, see

The main fruiting season is in summer and fall. Some fruit may ripen at other times, but usually not in winter and early spring. 1
Mature jackfruit trees may produce from 40 to over 250 pounds (18–114 kg) per tree, depending on the cultivar, weather, and cultural practices. Trees that average 150 pounds (68 kg) per tree or more are considered good producers. 1
Harvest fruit with clippers or loppers. The cut stem will immediately exude white, sticky latex; this latex will permanently stain clothing. Wrap the cut end with a paper towel to make handling easier, or set the fruit on its side until the flow of latex ceases. 1
Jackfruit are wind and insect pollinated, and generally fruit set and fruit quality is enhanced by cross pollination among different cultivars (or seedlings). 1

Fig. 25. Male fruits emerge first and the female fruits are pollinated after emergence
Fig. 26. Pollen laden male flowers and receptive female flowers are fuzzy. To pollinate, pick male fruit and brush it against female fruit.
Fig. 27. Hand pollination ensures development of female fruits. Female fruits insufficiently pollinated will fall from the tree before maturing.
Fig. 28. The smaller male fruit rapidly decays after dispensing its pollens.
Seed storage behaviour is recalcitrant. Viability is maintained for 2 years in moist storage at 15 deg. C, seeds kept in polythene bags filled with perlite at 6 deg. C. There are about 430 seeds/kg. 4
The jackfruit is well adapted to the hot humid tropics. Jackfruit grows well in the humid subtropical climate of south Florida along the coastal areas where there are only occasional freezes. Optimum growth and production occurs in continuously warm areas. 1
Cultural Calendar from the University of Florida
Young jackfruit trees do not need pruning during their first year. Shoot tip pruning once or twice during spring and summer will force lateral bud break and make the tree more compact. Non-pruned trees usually develop a strong central leader. During the second season, trees should be pruned to the first lateral branch, which will slow upward growth and enhance spreading of the canopy. As trees mature, upright vigorous shoots should be removed and the inner canopy thinned out at the end of the harvest season. 1
The number of fruit per tree or major limb should be limited to 1 on young trees, as heavy fruit loads have been observed to result in limb decline or death and tree stunting. On mature trees, limiting the number of fruit per major limb may enhance the quality and size of remaining fruit. 1
For mature trees, fertilizer should be applied 2 to 3 times from bloom to right after harvesting and pruning. Iron applications are most effective from May to September, and foliar sprays from April to September. 1
A means of watering young trees should be available for newly planted and young trees. Regular watering during dry periods is recommended for newly planted and young trees. For mature trees watering is recommended during dry periods and is critical from bloom through fruit development. 1
Pest and Disease Page
Jackfruit may be eaten as a vegetable when picked at an immature stage or eaten fresh when picked at a mature stage and allowed to ripen. Immature fruit are usually 1 to 3 months old, are green and may be harvested for cooking. 1
Green, immature fruit may be used as a vegetable in cooking including soups, baked dishes, and fried. The pulp of ripe fruit may be eaten fresh, dried, or preserved in syrup or used for salads. The seeds can be boiled and roasted (eaten as a nut) and have a chestnut flavor. 1
Because unripe jackfruit has a meat-like taste, it is used in curry dishes with spices in Bihar, Jharkhand, Sri Lankan, Andhran, eastern Indian Bengali, Odisha and Keralan cuisines. The skin of unripe jackfruit must be peeled first; then the remaining whole jackfruit can be chopped into edible portions and cooked before serving. Young jackfruit has a mild flavor and distinctive meat-like texture and is compared to poultry. Meatless sandwiches have been suggested and are popular with both vegetarian and nonvegetarian populations. 7
Arils can be fermented and distilled to produce an alcoholic beverage. 4

Medicinal Uses **
All parts of the plant have medicinal properties. The root is a remedy for skin diseases and asthma and the extract is taken in cases of fever and diarrhea.
The ashes of the leaves, burned together with corn and coconut shells are used alone or mixed with coconut oil to heal ulcers. Mixed with vinegar, the latex promotes healing of abscesses, snakebite and glandular swellings. Heated leaves alone are placed on wounds and the bark is made into poultices. The seed starch is given to relieve biliousness and the roasted seeds are regarded as aphrodisiac. In Chinese medicine the pulp and seeds are considered tonic and nutritious. 2
The wood contains the yellow colorant, morin and the colorless cyanomaclurin. In 1955, workers in Bombay reported and a new yellow colorant called artocarpin. And the National Chemical Laboratory in Poona has isolated other six flavonoids. 2
A rich yellow dye used for dyeing silk and the cotton robes of Buddhist priests is made from the wood chips boiled with alum. The bark is occasionally made into cordage or cloth.
The wood is beautiful, resembling mahogany and changing with age from orange or yellow to brown or dark-red.
It has many qualities: it is termite proof, fairly resistant to fungal and bacterial decay, which makes it superior to teak (its strength is 75 to 80% that of teak) for furniture, construction, turnery and musical instruments. 2
The generic name comes from the Greek words ‘artos’ (bread) and ‘karpos’ (fruit); the fruits are eaten and are commonly called breadfruit. The specific name, ‘heterophyllus’, is Latin for various leaved, or with leaves of different sizes and shapes; it is from the Greek word ‘heteros’ (different). 4
