What is the tangelo? Origin and development of the hybrid
The tangelo, whose scientific name is Citrus x tangelo, is a fruit tree belonging to the Rutaceae family that is part of the broad group of citrus fruits. This species is the result of a hybrid cross between the mandarin (Citrus reticulata) and grapefruit (Citrus Paradisi) or the pomelo (citrus maxima), in order to obtain a fruit that combines the sweetness and aroma of mandarin with the juiciness y size Grapefruit. The hybridization process was carried out to preserve and enhance the characteristic nutritional properties of citrus fruits.
The development of tangelo responds to both agricultural and commercial interests, since the fruits obtained are easier to peel thanks to their loose skin, variations in the number of seeds (some practically lack them) and a pulp with a high juice contentThe taste, attractive to consumers, is halfway between the sweetness of mandarin and the acidic nuance of grapefruit.
Botanical and morphological characteristics of the tangelo
The tangelo is a perennial fruit tree With a long lifespan and a vigorous appearance, it has a rounded crown and sloping branches, giving it a characteristic appearance among citrus trees.
The leaves are of a intense green or light green, robust and shiny, giving the tree a high leaf density. Flowering occurs once a year, usually in spring, producing extremely white flowers. fragrant and aromatic plants that, after pollination, give way to a large, juicy, thin-skinned fruit.
The fruit of the tangelo It is approximately the size of an adult's fist, with easy-to-peel, though somewhat rough, skin. Its typical color is deep orange, with a pulp between orange and yellow, and its flavor It is a perfect balance of sweetness and acidity. Another notable characteristic is the presence of a bulge in the upper stem of the fruit.
The pulp is firm, very juicy, and, depending on the variety and pollination, can be found with few seeds or completely seedless, which improves its acceptance for direct consumption or in juice.
Most cultivated tangelo varieties
There are several varieties of tangelo, adapted to different regions and climatic conditions. Each one presents unique nuances in terms of flavor, size, color, juice content, and seed quantity. Among the best-known and most cultivated are:
- Tangelo Minneola: It is one of the most popular hybrids. It is obtained from the cross between a Dancy mandarin and a Bowen grapefruit. The Minneola fruit is appreciated for its sweetness, abundant juice and a peculiar shape, with a slight bulge near the stem. It requires fresh, nutrient-rich soil and a steady water supply. It usually has a loosely attached shell and a few seeds.
- Tangelo Orlando: It comes from a combination of mandarin and grapefruit, recognized for its Smooth flavor, easy-to-peel shell and an optimal balance between sweetness and acidity.
- Tangelo Honeybell: Famous for its exceptionally sweet taste and juicy, almost seedless. Its harvest period is short, but it is highly valued in the fresh fruit market.
- Tangelo Nova: A cross between a clementine and a Minneola, it has a similar rind, plenty of juice, and contains several seeds. The Nova plant tolerates cold well.
- Tangelo Ugli: It emerged accidentally, the result of crossing a mandarin and a grapefruit. It has a less intensely colored, greener, and less sticky peel, with yellow, very juicy flesh and a pleasant flavor. It is usually seedless.
- Tangelo Sampson and Seminole: Other less common varieties but with similar characteristics: thin skin, balanced flavor and high juice production.
History and geographical distribution
The origin of the tangelo is attributed to human ingenuity in the search for sweeter, juicier citrus fruits. It is believed that the first records date back to Asia, with a long history of cultivation and hybridization. Later, its development was boosted in regions such as Florida and California, where commercial tangelo production was consolidated due to its optimal adaptation to the subtropical climate and the growing demand for new citrus fruits.
Today, The tangelo is grown all over the world where climatic and soil conditions permit. Plantations are prominent in North and South America, Europe, Australia, and the Mediterranean.
Climate and soil requirements for tangelo cultivation
The success of tangelo cultivation is closely linked to the environmental conditions.
- Climate: It prefers temperate or subtropical climates. It tolerates temperatures between 13 and 38°C for optimal growth, with the ideal range being between 18 and 29°C. It is especially sensitive to frost., so it is recommended to take additional precautions in regions with cold winters.
- Humidity: High levels of relative humidity (around 87%) favor the growth of both the tree and the fruit. It is important to avoid extremely dry conditions.
- Ground: Tangelos thrive in deep, fertile, well-drained, stone-free soils; they avoid compacted or waterlogged soils. They prefer a pH between 6.0 and 7.5. The presence of organic matter significantly improves moisture retention and nutrient delivery.
Land preparation, planting and cultivation framework
Proper land preparation is essential:
- Cleaning and weeding: Stones, plant debris, and weeds are removed to prevent competition and facilitate root development.
- Background fertilizer: It is advisable to incorporate organic fertilizer (mature compost, manure) into the planting hole to improve the structure and enrich the soil.
- Selection of seedlings: Healthy, certified plants free of disease or pests should be chosen.
- Planting frame: It is recommended to space the trees at 4 meters between plants and 5 meters between rowsThis framework promotes proper ventilation, facilitates access to light, and reduces the incidence of disease.
- Plantation: It is best done in spring or fall. The hole should be large enough to accommodate the roots without forcing them. After planting, water thoroughly to settle the soil and eliminate air pockets.
Essential care: watering, fertilizing and pruning
The tangelo requires specific care throughout its productive life. to ensure healthy development and optimal fruit production.
Irrigation: Watering should be regular and moderate, avoiding waterlogging Soil. A drip or sprinkler irrigation system is recommended, maintaining humidity but without saturating the substrate, especially during dry seasons. In commercial cultivation areas, the estimated need is between 8,000 and 9,000 m² of water per hectare using gravity irrigation.
Fertilization: Organic fertilizer should be applied during planting and NPK fertilizers (nitrogen, phosphorus, and potassium) should be applied at different stages of development. Fertilization should be reinforced before flowering and after harvest to replenish nutrients. It is also important to provide micronutrients such as iron, Magnesium y zinc to avoid specific deficiencies.
Pruning: Formative and maintenance pruning is necessary to remove dry, diseased, or damaged branches and improve ventilation and light distribution in the canopy. It is best done in spring or fall, outside of flowering and fruiting periods.
Cultural work: In addition to pruning, weeding and regular weed control are essential to minimize resource competition and limit the incidence of pests and diseases.
Flowering, fruiting and harvesting of the tangelo
The tangelo's reproductive cycle begins with the annual flowering. After pollination, the fruit begins to grow and usually ripens in winter or spring, although the period may vary depending on the local climate and the variety grown.
- Harvest: It is done when the fruit reaches its characteristic orange color and the desired balance of sugars and acidity. The fruit should peel easily, indicating that it is at its optimal ripeness.
- Post-harvest handling: It is crucial to handle the fruits carefully to avoid bruising or damage, and to store them in cool conditions (0°C to 5°C) to prolong their preservation and commercial quality.
Harvested tangelo can maintain its quality for several weeks if the cold chain and relative humidity are adequate.
