The fruit, botanically named sorosis, is a modification of the entire pistillate catkin and contains 100-500 large, oily seeds. The edible, pulpy part represents the parianth. It is the national fruit of Bangladesh.
Jackfruit trees are seen throughout Bangladesh but is grown in abundance in Naogaon, Dinajpur, Savar, Madhupur and Sylhet.
The jackfruit plant is an evergreen tree, 9 to 25 m high, and possesses milky latex in all parts. Its stems are straight, branching near the base, and forming dense, irregular crowns. The staminate flowers are borne in slender, dropping catkins formed at the end, or leaf axils of small branches. The jack plant flourishes best in a humid, warm climate, requires plenty of soil moisture, open textured deep-alluvial soil, and good drainage. Fruits contain vitamins A and C, while the seeds contain carbohydrate, protein and fat. The juicy pulp of the ripe fruit is eaten fresh, as a dessert, or is preserved in syrup. The seeds are eaten cooked, roasted or fried. The young fruit is consumed as a vegetable and also made into pickles.
