Mango

Mangifera indica is native to the Indian subcontinent and Indochina, with its center of origin believed to be the region encompassing northeastern India, Myanmar, and Bangladesh.

• The genus Mangifera comprises approximately 69 species, with the highest diversity found in the Malay Peninsula, Borneo, and Sumatra
• Wild ancestors (Mangifera indica var. silvestris) still grow in the foothills of the Himalayas and in the forests of northeastern India
• Archaeological and linguistic evidence suggests domestication began at least 4,000–6,000 years ago in the Indian subcontinent
• Spread eastward to Southeast Asia by the 5th century BCE, and later to East Africa, Brazil, the Caribbean, and other tropical regions via Portuguese and Spanish traders from the 16th century onward
• The Portuguese introduced mangoes to Africa and Brazil in the 1500s; the first recorded planting in Hawaii was in the early 1800s

Mangifera indica is a large, spreading evergreen tree that can reach impressive dimensions under favorable conditions.

Tree Architecture:
• Height: typically 10–30 m in cultivation; wild specimens can exceed 40 m
• Crown: dense, broad, and rounded, with a canopy spread of 10–15 m
• Trunk: stout, often 60–120 cm in diameter, with rough, dark brown to grey bark that cracks with age
• Root system: a deep taproot (up to 6–8 m) supplemented by extensive lateral roots, contributing to drought tolerance

Leaves:
• Simple, alternate, lanceolate to oblong-lanceolate
• Size: 15–35 cm long, 4–8 cm wide
• Texture: leathery (coriaceous), glossy dark green above, paler beneath
• Young leaves emerge in flushes, often displaying striking reddish, pinkish, or bronze coloration before maturing to green
• Leaves contain bioactive phenolic compounds, including mangiferin

Flowers:
• Produced in large terminal panicles (inflorescences) 10–40 cm long
• Individual flowers are small (~5–10 mm), pentamerous, with five petals ranging from white to pale yellow or pinkish
• Each panicle bears hundreds to thousands of flowers, but only a small fraction (typically <1%) set fruit
• Pollinated primarily by flies, bees, and other insects; wind plays a minor role
• The tree is andromonoecious — panicles bear both perfect (bisexual) and functionally male flowers

Fruit:
• A fleshy drupe, highly variable in size and shape depending on cultivar
• Size: typically 5–25 cm long, weighing 150 g to over 2 kg
• Skin (epicarp): smooth, waxy; color at maturity ranges from green to yellow, orange, red, or combinations thereof
• Flesh (mesocarp): soft to firm, juicy, ranging from pale yellow to deep orange; flavor profile varies from intensely sweet to tangy
• Contains a single large, flattened, fibrous seed (stone/endocarp) encased in a hard shell
• The seed is recalcitrant — it cannot survive desiccation and must be planted fresh for germination

Mangifera indica thrives in tropical and subtropical climates with a distinct dry season that promotes flowering.

Climate Requirements:
• Optimal temperature range: 24–30°C
• Sensitive to frost; prolonged temperatures below 1°C can kill young trees
• Requires a pronounced dry period (2–4 months) to initiate flowering — this is why mangoes in equatorial regions with year-round rainfall may fruit irregularly
• Annual rainfall of 750–2,500 mm is suitable, but a dry spell during flowering is essential for good fruit set

Soil Preferences:
• Adaptable to a wide range of soil types, from sandy loam to laterite
• Prefers deep, well-drained soils with a pH of 5.5–7.5
• Intolerant of waterlogged or poorly drained conditions

Ecological Interactions:
• Flowers attract a diverse community of pollinators, particularly flies (Muscidae, Calliphoridae) and stingless bees
• Fruit bats and birds serve as seed dispersal agents in wild populations
• The tree provides habitat and food for numerous insect species, including the mango leafhopper (Idioscopus spp.) and mango fruit fly (Bactrocera dorsalis)
• Mango trees form associations with arbuscular mycorrhizal fungi, which enhance phosphorus uptake

The mango fruit is nutritionally rich and provides a wide array of vitamins, minerals, and bioactive compounds.

Per 100 g of raw mango flesh (approximate values):
• Energy: ~60 kcal
• Carbohydrates: ~15 g (primarily sugars: sucrose, glucose, fructose)
• Dietary fiber: ~1.6 g
• Protein: ~0.8 g
• Fat: ~0.4 g

Vitamins:
• Vitamin C: ~36 mg (approximately 40–60% of the daily recommended intake)
• Vitamin A (as beta-carotene): ~54 µg RAE — the deep orange flesh of ripe mangoes is particularly rich in provitamin A carotenoids
• Vitamin E: ~0.9 mg
• Vitamin K: ~4.2 µg
• Folate (B9): ~43 µg
• Contains smaller amounts of B1, B2, B3, B5, and B6

Minerals:
• Potassium: ~168 mg
• Magnesium: ~10 mg
• Calcium: ~11 mg
• Phosphorus: ~14 mg
• Iron: ~0.16 mg

Bioactive Compounds:
• Mangiferin: a C-glucosylxanthone with studied antioxidant, anti-inflammatory, and potential antidiabetic properties
• Gallotannins and other polyphenols concentrated in the peel and seed kernel
• Carotenoids (beta-carotene, violaxanthin, neoxanthin) responsible for the orange-yellow flesh color

Mango belongs to the family Anacardiaceae, which includes poison ivy and poison sumac. The plant contains urushiol-related phenolic compounds that can cause contact dermatitis in sensitive individuals.

• The peel, sap, and leaves of the mango tree contain urushiol and related alkenylcatechols
• Individuals sensitive to poison ivy may develop allergic contact dermatitis from handling mango peel or tree sap
• The fruit flesh itself is generally safe and does not contain significant levels of these irritants
• Burning mango wood or leaves can release irritating smoke that may cause respiratory and skin reactions
• Mango kernel and leaves have been reported to be toxic to livestock if consumed in large quantities

Mango is one of the most widely cultivated fruit trees in the tropics, grown both commercially and in home gardens.

Climate & Site:
• Best grown in tropical and warm subtropical zones (USDA hardiness zones 10–11)
• Requires full sun — at least 6–8 hours of direct sunlight daily
• Choose a sheltered site protected from strong winds, which can damage flowers and young fruit

Soil:
• Deep, well-drained loamy or sandy loam soil is ideal
• Avoid heavy clay or waterlogged sites
• Soil pH of 5.5–7.5 is optimal

Planting:
• Propagation is most commonly by grafting (veneer grafting or cleft grafting) to maintain cultivar characteristics
• Seed-grown trees are genetically variable and take 5–8 years to fruit, compared to 3–5 years for grafted trees
• Plant spacing for commercial orchards: typically 8–12 m between trees

Watering:
• Young trees require regular irrigation during establishment
• Mature trees are relatively drought-tolerant but benefit from supplemental irrigation during flowering and fruit development
• Reduce watering during the pre-flowering dry period to promote blooming

Pruning:
• Minimal pruning required; remove dead, diseased, or crossing branches
• Post-harvest pruning helps maintain tree size and shape
• Open-center or modified central-leader training systems are commonly used

Common Pests & Diseases:
• Mango fruit fly (Bactrocera dorsalis) — a major commercial pest
• Mango seed weevil (Sternochetus mangiferae)
• Anthracnose (Colletotrichum gloeosporioides) — the most significant fungal disease, affecting flowers, leaves, and fruit
• Powdery mildew (Oidium mangiferae)
• Mango malformation disease (associated with Fusarium spp.)

The mango is an extraordinarily versatile plant with uses spanning food, medicine, industry, and culture.

Culinary Uses:
• Fresh fruit consumption — eaten ripe or unripe (green) across cuisines worldwide
• Unripe mango used in pickles, chutneys, salads, and savory dishes (e.g., Indian aam ka achaar, Thai som tam)
• Processed into juice, nectar, jam, jelly, dried slices, and mango leather (aam papad)
• Mango pulp is a key ingredient in ice cream, yogurt, smoothies, and confectionery
• Mango kernel fat (mango butter) is used in chocolate and cosmetics as a cocoa butter substitute

Traditional Medicine:
• In Ayurvedic medicine, various parts of the mango tree (bark, leaves, fruit, seed) are used to treat diarrhea, dysentery, and urinary disorders
• Mangiferin, a bioactive xanthone found in mango bark and leaves, has been studied for antioxidant, anti-inflammatory, and potential antidiabetic properties
• Mango leaf decoctions have been traditionally used to manage blood sugar levels

Timber & Industrial Uses:
• Mango wood is used for furniture, flooring, plywood, and musical instruments (e.g., ukuleles)
• The wood is considered a sustainable timber source since trees are often felled after their fruit-bearing years
• Tannins from the bark have been used in leather tanning

Cultural Significance:
• The mango holds sacred status in Hinduism and Buddhism; the Buddha is said to have meditated in mango groves
• Mango leaves are used as decorations and auspicious symbols in Indian weddings and festivals
• The mango motif appears extensively in South Asian art, textiles, and architecture
• In the Philippines, the mango is celebrated in annual festivals such as the Guimaras Mango Festival
