( Breadfruit)
Breadfruit (Artocarpus altilis) is a tree and fruit native to the Malay Peninsula and western Pacific islands. It has also been widely planted in tropical regions elsewhere. It was collected and distributed by Lieutenant William Bligh as one of the botanical samples collected by HMS Bounty in the late 18th century, on a quest for cheap, high-energy food sources for British slaves in the West Indies. Breadfruit trees grow to a height of 20 m (66 ft). The large and thick leaves are deeply cut into pinnate lobes. All parts of the tree yield latex, a milky juice, which is used for boat caulking. The trees are monoecious, with male and female flowers growing on the same tree. The male flowers emerge first, followed shortly afterward by the female flowers, which grow into a capitulum, which are capable of pollination just three days later. The pollinators are Old World fruit bats (Family Pteropodidae). The compound, false fruit develops from the swollen perianth and originates from 1,500-2,000 flowers. These are visible on the skin of the fruit as hexagon-like disks. Breadfruit is one of the highest-yielding food plants, with a single tree producing up to 200 or more fruits per season. In the South Pacific, the trees yield 50 to 150 fruits per year. In southern India, normal production is 150 to 200 fruits annually. Productivity varies between wet and dry areas. In the West Indies, a conservative estimate is 25 fruits per tree. Studies in Barbados indicate a reasonable potential of 6.7 to 13.4 tons per acre (16-32 tons/ha). Much higher yields have been forecast, but experts are skeptical and view these predictions as unrealistic. The grapefruit-sized ovoid fruit has a rough surface, and each fruit is divided into many achenes, each achene surrounded by a fleshy perianth and growing on a fleshy receptacle. Some selectively-bred cultivars have seedless fruit.
