Noni (Morinda citrifolia), also known as Indian mulberry, great morinda, or cheese fruit, is a tropical evergreen tree or shrub belonging to the coffee family (Rubiaceae). It is one of the most widely distributed traditional medicinal and food plants in the Pacific Islands, Southeast Asia, and Australasia.
• Native to Southeast Asia and Australasia, now pantropical in distribution
• Known by over 100 common names across Polynesia, Melanesia, Micronesia, and Southeast Asia
• In Hawaiian, it is called 'noni'; in Malay, 'mengkudu'; in Samoan, 'nonu'
• Has been used for over 2,000 years in traditional Polynesian medicine
• All parts of the plant — roots, bark, leaves, flowers, and fruit — have been utilized in folk remedies
• The ripe fruit has a pungent, cheese-like odor that many find unpleasant, earning it the nickname 'vomit fruit' or 'cheese fruit'
• Despite its strong smell, noni has gained global popularity as a health supplement and functional food
분류학
• Indigenous to regions spanning from Thailand, Vietnam, and Malaysia through the Indonesian archipelago to northern Australia and the Pacific Islands
• Spread across the Pacific by ancient Austronesian and Polynesian voyagers, who carried it as a canoe plant (a plant transported by early seafaring peoples for food and medicine)
• Archaeological and ethnobotanical evidence suggests intentional cultivation and use for at least 2,000 years in Polynesia
• Now naturalized pantropically — found throughout the tropics in the Caribbean, Central and South America, West Africa, and across the Pacific
• Thrives in coastal lowlands, volcanic soils, limestone areas, and disturbed secondary forests
• The genus Morinda comprises approximately 80 species, with M. citrifolia being the most economically important
Trunk & Bark:
• Trunk is gray to light brown, rough, and fissured
• Bark contains a yellow to reddish dye compound (morindin) used traditionally for textile dyeing
• Wood is soft and lightweight
Leaves:
• Large, simple, opposite, and decussate (each pair at right angles to the next)
• Elliptical to ovate, 10–40 cm long and 5–25 cm wide
• Glossy dark green upper surface with prominent venation
• Leaf margins entire; petioles 1.5–2 cm long
• Leaves are among the largest in the Rubiaceae family
Flowers:
• Small, white, tubular, fragrant
• Borne in dense, globose heads (capitula) ~2.5 cm in diameter
• Each flower has 5 petals fused into a tube ~1.5 cm long
• Flowers are protandrous (male parts mature before female parts), promoting cross-pollination
• Blooming occurs year-round in tropical climates
Fruit:
• A multiple fruit (syncarp) formed from the fusion of many drupes
• Ovoid to irregularly ellipsoid, 4–12 cm long
• Color changes from green to pale yellow to white or translucent as it ripens
• Surface becomes bumpy and warty with distinctive polygonal segments
• Ripe fruit has a strong, pungent odor caused by short-chain fatty acids (particularly caproic and caprylic acid)
• Contains numerous small reddish-brown seeds (~4 mm long)
• Fruit is soft and juicy when ripe, with a bitter, cheese-like flavor
Roots:
• Extensive root system capable of penetrating rocky and volcanic soils
• Roots and bark contain anthraquinone compounds (morindin, alizarin) valued as natural dyes
Habitat Preferences:
• Coastal strands, lava flows, volcanic soils, limestone outcrops, and coral atolls
• Secondary forests, disturbed areas, roadsides, and abandoned agricultural land
• Tolerates saline soils, drought, waterlogging, and poor nutrient conditions
• Often one of the first plants to colonize bare volcanic rock and degraded land
Environmental Tolerance:
• Thrives in full sun but tolerates partial shade
• Grows in soils with pH ranging from acidic to alkaline (pH 5.0–8.0)
• Tolerant of salt spray and coastal winds
• Can survive prolonged drought once established
• Temperature range: 15–35°C optimal; frost-sensitive
Pollination & Seed Dispersal:
• Flowers are pollinated primarily by insects, including bees and small flies
• Fruit bats (Pteropodidae) are important seed dispersers in the Pacific
• Frugivorous birds also contribute to seed dispersal
• Seeds can remain viable after passing through animal digestive tracts
• Seeds can also be dispersed by ocean currents, contributing to the plant's wide coastal distribution
Ecological Role:
• Pioneer species in ecological succession on degraded and volcanic land
• Provides food and habitat for fruit bats, birds, and insects
• Root system helps stabilize soil and prevent erosion on coastal and volcanic terrain
Climate:
• Best suited to USDA hardiness zones 10–11
• Requires warm temperatures year-round; optimal range 20–35°C
• Cannot tolerate frost; temperatures below 5°C can cause damage
• Grows well in areas with 700–4,000 mm annual rainfall
Light:
• Prefers full sun for optimal fruit production
• Tolerates partial shade but with reduced fruiting
Soil:
• Extremely adaptable — grows in sandy, loamy, clay, volcanic, and limestone soils
• Tolerates saline and alkaline conditions
• Requires well-drained soil; does not tolerate prolonged waterlogging
• pH range: 5.0–8.0
Watering:
• Drought-tolerant once established
• Regular watering improves fruit yield and size
• Avoid waterlogging, which can cause root rot
Propagation:
• Seeds: most common method; seeds germinate in 2–6 weeks; seedlings may take 12–18 months to fruit
• Stem cuttings: semi-hardwood cuttings root readily in moist media
• Air layering: effective for maintaining desirable cultivar traits
• Seed viability decreases with storage time; fresh seeds have highest germination rates
Spacing:
• Trees planted 3–4 meters apart for orchard cultivation
Harvesting:
• Fruit can be harvested year-round in tropical climates
• Typically harvested when turning from green to pale yellow or white
• Fruit ripens rapidly after harvest and should be processed within 1–3 days
Common Problems:
• Fruit fly infestations (Bactrocera spp.) can damage fruit
• Scale insects and mealybugs may colonize leaves and stems
• Root rot in poorly drained soils
• Generally resistant to most serious diseases and pests
재미있는 사실
Noni holds a unique place in human history as one of the most important 'canoe plants' carried by ancient Polynesian navigators across thousands of kilometers of open Pacific Ocean. • Polynesian voyagers deliberately transported noni on their double-hulled canoes because of its medicinal value, considering it essential for survival on new islands • In traditional Hawaiian medicine, noni was used to treat over 40 different ailments, from skin infections to digestive disorders • The yellow-red dye extracted from noni roots (morindin) has been used for centuries to dye tapa cloth and textiles across Polynesia and Southeast Asia • During World War II, noni fruit was recommended to U.S. and Allied troops stationed in the South Pacific as an emergency food source; the U.S. Army included it in survival manuals • Noni seeds are remarkably buoyant and salt-tolerant — they can float in seawater for months and still germinate, which explains the plant's natural dispersal across vast ocean distances • A single noni tree can produce 4–8 kg of fruit per month year-round, making it one of the most productive tropical fruit trees • The strong odor of ripe noni fruit is caused by the same short-chain fatty acids (caproic acid and caprylic acid) found in goat cheese — hence the nickname 'cheese fruit' • Noni is sometimes called 'the painkiller tree' in the Caribbean, where it has been used traditionally to relieve pain and inflammation • In a 2009 survey, noni was ranked among the top 10 most important medicinal plants used in Pacific Island traditional medicine
