| + | Adaptation Bananas and plantains are today grown in every humid tropical region and constitutes the 4th largest fruit crop of the world. The plant needs 10 - 15 months of frost-free conditions to produce a flower stalk. All but the hardiest varieties stop growing when the temperature drops below 53° F. Growth of the plant begins to slow down at about 80° F and stop entirely when the temperature reaches 100° F. High temperatures and bright sunlight will also scorch leaves and fruit, although bananas grow best in full sun. Freezing temperatures will kill the foliage. In most areas bananas require wind protection for best appearance and maximum yield. They are also susceptible to being blown over. Bananas, especially dwarf varieties, make good container specimens if given careful attention. The plant will also need periodic repotting as the old plant dies back and new plants develop. |
| + | |
| + | Growth Habit: Bananas are fast-growing herbaceous perennials arising from underground rhizomes. The fleshy stalks or pseudostems formed by upright concentric layers of leaf sheaths constitute the functional trunks. The true stem begins as an underground corm which grows upwards, pushing its way out through the center of the stalk 10-15 months after planting, eventually producing the terminal inflorescence which will later bear the fruit. Each stalk produces one huge flower cluster and then dies. New stalks then grow from the rhizome. Banana plants are extremely decorative, ranking next to palm trees for the tropical feeling they lend to the landscape. |
| + | |
| + | Foliage: The large oblong or elliptic leaf blades are extensions of the sheaths of the pseudostem and are joined to them by fleshy, deeply grooved, short petioles. The leaves unfurl, as the plant grows, at the rate of one per week in warm weather, and extend upward and outward , becoming as much as 9 feet long and 2 feet wide. They may be entirely green, green with maroon splotches, or green on the upper side and red-purple beneath. The leaf veins run from the mid-rib straight to the outer edge of the leaf. Even when the wind shreds the leaf, the veins are still able to function. Approximately 44 leaves will appear before the inflorescence. |
| + | |
| + | Flowers: The banana inflorescence shooting out from the heart in the tip of the stem, is at first a large, long-oval, tapering, purple-clad bud. As it opens, the slim, nectar-rich, tubular, toothed, white flowers appear. They are clustered in whorled double rows along the the floral stalk, each cluster covered by a thick, waxy, hood like bract, purple outside and deep red within. The flowers occupying the first 5 - 15 rows are female. As the rachis of the inflorescence continues to elongate, sterile flowers with abortive male and female parts appear, followed by normal staminate ones with abortive ovaries. The two latter flower types eventually drop in most edible bananas. |
| + | |
| + | Fruits: The ovaries contained in the first (female) flowers grow rapidly, developing parthenocarpically (without pollination) into clusters of fruits, called hands. The number of hands varies with the species and variety. The fruit (technically a berry) turns from deep green to yellow or red, and may range from 2-1/2 to 12 inches in length and 3/4 to 2 inches in width. The flesh, ivory-white to yellow or salmon-yellow, may be firm, astringent, even gummy with latex when unripe, turning tender and slippery, or soft and mellow or rather dry and mealy or starchy when ripe. The flavor may be mild and sweet or subacid with a distinct apple tone. The common cultivated types are generally seedless with just vestiges of ovules visible as brown specks. Occasionally, cross-pollination with wild types will result in a number of seeds in a normally seedless variety. |

− | | + | Location: Bananas require as much warmth as can be given them. Additional warmth can be given by planting next to a building. Planting next to cement or asphalt walks or driveways also helps. Wind protection is advisable, not for leaf protection as much as for protection of the plant after the banana stalk has appeared. During these last few months propping should be done to keep the plant from tipping or being blown over. |

− | Bananas come in a variety of sizes and [[color]]s; most cultivars are yellow when ripe but some are red or purple-ish. The ripe fruit is easily peeled and eaten raw or cooked. Depending upon cultivar and ripeness, the flesh can be starchy to sweet, and firm to mushy. Unripe or "green" bananas and plantains are used in cooking and are the staple [[starch]] of many [[tropical]] populations.

| + | Soil: Bananas will grow in most soils, but to thrive, they should be planted in a rich, well-drained soil. The best possible location would be above an abandoned compost heap. They prefer an acid soil with a pH between 5.5 and 6.5. The banana is not tolerant of salty soils. |
− | ing transported to market. Even when only transported within their country of origin, ripe bananas suffer a high rate of damage and loss.
| |
| | | |
− | The commercial dessert cultivars most commonly eaten in [[temperate]] countries (species ''Musa acuminata'' or the [[hybrid]] ''Musa × paradisiaca'', a [[cultigen]]) are imported in large quantities from the [[tropics]]. They are popular in part because being a non-seasonal crop they are available fresh year-round. In global commerce, by far the most important of these banana [[cultivar]]s is '[[Cavendish banana|Cavendish]]', which accounts for the vast bulk of bananas exported from the tropics. The Cavendish gained popularity in the [[1950]]s after the previously mass produced cultivar, [[Gros Michel]], was destroyed by [[Panama disease]], a fungus which attacks the roots of the banana plant. | + | Irrigation: The large leaves of bananas use a great deal of water. Regular deep watering is an absolute necessity during warm weather. Do not let plants dry out, but do not overwater. Standing water, especially in cool weather, will cause root rot. Plants grown in dry summer areas such as Southern California need periodic deep waterings to help leach the soil of salts. Spread a thick layer of mulch on the soil to help conserve moisture and protect the shallow roots. Container grown plants should be closely watched to see that they do not dry out. An occasional deep watering to leach the soil is also helpful. |
| | | |
− | The most important properties making 'Cavendish' the main export banana are related to transport and shelf life rather than taste; major commercial cultivars rarely have a superior flavour compared to the less widespread cultivars. Export bananas are picked green, and then usually ripened in ripening rooms when they arrive in their country of destination. These are special rooms made air-tight and filled with [[ethylene]] gas to induce ripening. Bananas can be ordered by the retailer "ungassed", however, and may show up at the supermarket still fully green. While these bananas will ripen more slowly, the flavour will be notably richer, and the banana peel can be allowed to reach a yellow/brown speckled phase, and yet retain a firm flesh inside. Thus, shelf life is somewhat extended. The flavour and texture of bananas are affected by the temperature at which they ripen. Bananas are refrigerated to between 13.5 and 15 °C (57 and 59 °F) during transportation. At lower temperatures, the ripening of bananas permanently stalls, and the bananas will eventually turn grey.
| + | Fertilization: Their rapid growth rate make bananas heavy feeders. During warm weather, apply a balanced fertilizer once a month--a 8:10:8 NPK fertilizer appears to be adequate. A mature plant may require as much as 1-1/2 to 2 pounds of the above fertilizer each month. Young plants need a quarter to a third as much. Spread the fertilizer evenly around the plant in a circle extending 4 - 8 feet from the trunk. Do not allow the fertilizer to come in contact with the trunk. Feed container container plants on the same monthly schedule using about half the rate for outside plants. |
| | | |
− | [[Image:Banane Rose.JPG|thumb|250px|right|Certain banana cultivars turn red or purplish instead of yellow as they ripen.]]
| + | Frost Protection: Bananas flourish best under uniformly warm conditions but can survive 28° F for short periods. If the temperature does not fall below 22° F and the cold period is short, the underground rhizome will usually survive. To keep the plants that are above ground producing, protection against low temperatures is very important. Wrap trunk or cover with blanket if the plants are small and low temperatures are predicted. |
− | It should be noted that ''Musa × paradisiaca'' is also the generic name for the common [[plantain]], a coarser and starchier variant not to be confused with ''Musa acuminata'' or the Cavendish variety. Plantains have all but replaced the Cavendish in markets dominated by supply-side logistics.
| |
| | | |
− | In addition to the fruit, the [[flower]] of the banana plant (also known as ''banana blossom'' or ''banana heart'') is used in [[Southeast Asia]]n, [[Bengali cuisine|Bengali]] and [[Kerala]] (India) cuisine, either served raw with dips or cooked in soups and curries. The tender core of the banana plant's trunk is also used, notably in the [[Myanmar|Burmese]] dish [[mohinga]], Bengali and Kerala cooking. [[Pisang goreng|Bananas fried with batter]] is a popular dessert in [[Malaysia]], [[Singapore]] and [[Indonesia]]. Banana fritters can be served with ice-cream as well. Bananas are also eaten deep fried, baked in their skin in a split bamboo, or steamed in [[glutinous rice]] wrapped in a banana leaf in [[Myanmar]] where bunches of green bananas surrounding a green coconut in a tray is an important part of traditional offerings to the [[Buddha]] and the [[Nat (spirit)]]s. The juice extract prepared from the tender core is used to treat kidney stones.
| + | Pruning Only one primary stem of each rhizome should be allowed to fruit. All excess shoots should be removed as soon as they are noticed. This helps channel all of of the plant's energy into fruit production. Once the main stalk is 6 - 8 months old, permit one sucker to develop as a replacement stalk for the following season. When the fruit is harvested, cut the fruiting stalk back to 30 inches above the ground. Remove the stub several weeks later. The stalk can be cut into small pieces and used as mulch. |
| | | |
− | [[Image:IMG banana-offering.JPG|thumb|left|Traditional offerings of bananas and coconut at a Nat spirit shrine in Myanmar]]
| + | Fruit Harvest: Stalks of bananas are usually formed in the late summer and then winter over. In March they begin "plumping up" and may ripen in April. Occasionally, a stalk will form in early summer and ripen before cold weather appears. The fruit can be harvested by cutting the stalk when the bananas are plump but green. For tree-ripened fruit, cut one hand at a time as it ripens. If latter is done, check stalk daily as rodents can eat the insides of every banana, from above, and the stalk will look untouched. Once harvested the stalk should be hung in a cool, shady place. Since ethylene helps initiate and stimulate ripening, and mature fruit gives off this gas in small amounts, ripening can be hastened by covering the bunch with a plastic bag. Plantains are starchy types that are cooked before eating. |
− | The [[Leaf|leaves]] of the banana are large, flexible, and waterproof; they are used in many ways, including as [[umbrella]]s and to wrap food for cooking. [[China|Chinese]] [[zongzi]] (bamboo leaves are more commonly used where available) and [[Central America]]n [[tamale]]s are sometimes [[steaming|steamed]] in banana leaves, and the [[Hawaii]]an [[kalua|imu]] is often lined with them. [[Puerto Rico|Puerto Rican]] "pasteles" are boiled wrapped and tied inside the leaf. | |

− | e also been used in the making of [[jam]]. Unlike other fruits, it is difficult to extract juice from bananas because when compressed a banana simply turns to pulp.
| + | Propagation of bananas is done with rhizomes called suckers or pups. Very small pups are called buttons. Large suckers are the preferred planting material. These are removed from vigorous clumps with a spade when at least three feet tall, during warm months. Pups should not be taken until a clump has at least three to four large plants to anchor it. When the pup is taken the cut must be into the mother plant enough to obtain some roots. Plant close to the surface. Large leaves are cut off of the pup leaving only the youngest leaves or no leaves at all. Some nurseries supply banana plants as container grown suckers. |
| | | |
− | Seeded bananas (''Musa balbisiana''), considered to be one of the forerunners of the common domesticated banana, are sold in markets in Indonesia.
| + | In some countries, bananas are commercially propagated by means of tissue culture. This method is preferred since it ensures disease-free planting material. When using vegetative parts such as suckers for propagation, there is a risk of transmitting diseases (especially the devastating Panama disease). |
| | | |
− | It is reported that in [[Orissa]], [[India]], juice is extracted from the [[corm]] and used as a [[home remedy]] for the treatment of [[jaundice]]. In other places [[honey]] is mixed with mashed banana fruit and used for the same purpose.
| + | ===Pests and diseases=== |
| + | Bananas have few troublesome pests or diseases outside the tropics. Root rot from cold wet soil is by far the biggest killer of banana plants in our latitudes. California is extremely fortunate in not having nematodes that are injurious to the banana. Gophers topple them, and snails and earwigs will crawl up to where they can get continuous water, but these pests do not bother the plant. |

− | Bananas and plantains constitute a major staple [[food crop]] for millions of people in [[developing countries]]. In most tropical countries green (unripe) bananas used for [[cooking]] represent the main [[cultivar]]s. Cooking bananas are very similar to [[potato]]es in how they are used. Both can be [[frying|fried]], [[boiled]], [[baked]] or chipped and have similar [[taste]] and texture when served. One green cooking banana has about the same [[calorie]] content as one potato.{{Fact|date=February 2007}}
| |
− |
| |
− | In [[2003]], [[India]] led the world in banana production, representing approximately 23% of the worldwide crop, most of which was for domestic consumption. The four leading banana exporting countries were [[Ecuador]], [[Costa Rica]], [[Philippines]], and [[Colombia]], which accounted for about two-thirds of the world's exports, each exporting more than 1 million tons. Ecuador alone provided more than 30% of global banana exports, according to [[Food and Agriculture Organization|FAO]] statistics.

− | [[Image:Bananas.jpg|thumb|left|250 px|Bananas in a grocery store]]
| |
− | The vast majority of producers are small-scale [[farmer]]s growing the crop either for home consumption or for local markets. Because bananas and plantains will produce fruit year-round, they provide an extremely valuable source of food during the hunger season (that period of time when all the food from the previous harvest has been consumed, and the next harvest is still some time away). It is for these reasons that bananas and plantains are of major importance to [[food security]].
| |
− |
| |
− | Bananas are among the most widely consumed foods in the world. Most banana farmers receive a low unit price for their produce as supermarkets buy enormous quantities and receive a discount for that business. Competition amongst [[supermarkets]] has led to reduced margins in recent years which in turn has led to lower prices for growers. [[Chiquita Brands International|Chiquita]], [[Fresh Del Monte Produce|Del Monte]], [[Dole Food Company|Dole]] and [[Fyffes]] grow their own bananas in Ecuador, Colombia, Costa Rica, Guatemala and Honduras. Banana plantations are capital intensive and demand high expertise so the majority of independent growers are large and wealthy landowners of these countries. This has led to bananas being available as a "[[fair trade]]" item in some countries.
| |
− |
| |
− | The banana has an extensive trade history beginning with the founding of the [[United Fruit Company]] (now Chiquita) at the end of the nineteenth century. For much of the [[20th century]], bananas
| |
− | and [[coffee]] dominated the export economies of Central America. In the [[1930s]], bananas and coffee made up as much as 75 percent of the region's exports. As late as [[1960]], the two crops accounted for 67 percent of the exports from the region. Though the two were grown in similar regions, they tended not to be distributed together. The [[United Fruit Company]] based its business almost entirely on the banana trade, as the coffee trade proved too difficult for it to control. The term "[[banana republic]]" has been broadly applied to most countries in Central America, but from a strict economic perspective only Costa Rica, Honduras, and Panama were actual "banana republics", countries with economies dominated by the banana trade.
| |
− |
| |
− | The countries of the [[European Union]] have traditionally imported many of their bananas from the former European island colonies of the Caribbean, paying guaranteed prices above global market rates. As of 2005 these arrangements were in the process of being withdrawn under pressure from other major trading powers, principally the United States. The withdrawal of these indirect subsidies to Caribbean producers is expected to favour the banana producers of Central America, in which American companies have an economic interest.

| |
− | While the original bananas contained rather large seeds, [[polyploid|triploid]] (and thus seedless) cultivars have been selected for human consumption. These are propagated [[asexual reproduction|asexually]] from offshoots of the plant. The plant is allowed to produce 2 shoots at a time; a larger one for fruiting immediately and a smaller "sucker" or "follower" that will produce fruit in 6–8 months time. The life of a banana plantation is 25 years or longer, during which time the individual stools or planting sites may move slightly from their original positions as lateral rhizome formation dictates. Latin Americans sometimes comment that the plants are "walking" over time.
| |
− |
| |
− | Cultivated bananas are ''[[parthenocarpy|parthenocarpic]]'', which makes them sterile and unable to produce viable seeds. Lacking seeds, another form of propagation is required. This involves removing and transplanting part of the underground stem (called a [[corm]]). Usually this is done by carefully removing a sucker (a vertical shoot that develops from the base of the banana pseudostem) with some roots intact. However, small sympodial corms, representing not yet elongated suckers, are harder to transplant and can be left out of the ground for up to 2 weeks; they require minimal care and can be boxed together for shipment.
| |
− |
| |
− | In some countries, bananas are commercially propagated by means of tissue culture. This method is preferred since it ensures disease-free planting material. When using vegetative parts such as suckers for propagation, there is a risk of transmitting diseases (especially the devastating Panama disease).

| * [[Black Sigatoka]] - a fungal leaf spot disease first observed in [[Fiji]] in [[1963]] or [[1964]]. Black Sigatoka (also known as Black Leaf Streak) has spread to banana plantations throughout the tropics due to infected banana leaves being used as packing material. It affects all of the main cultivars of bananas and [[plantains]], impeding [[photosynthesis]] by turning parts of their leaves black, and eventually killing the entire leaf. Being starved for energy, fruit production falls by 50% or more, and the bananas that do grow suffer premature [[ripening]], making them unsuitable for [[export]]. The fungus has shown ever increasing resistance to fungicidal treatment, with the current expense for treating 1 hectare exceeding US$1000 per year. In addition to the financial expense there is the question of how long such intensive spraying can be justified environmentally. Several resistant cultivars of banana have been developed, but none has yet received wide scale commercial acceptance due to taste and texture issues. | | * [[Black Sigatoka]] - a fungal leaf spot disease first observed in [[Fiji]] in [[1963]] or [[1964]].

Minor traces of the radioactive substance [[trininite]] were spread by the wind over the town's main banana field; however, no serious problems occurred

− | Australia is relatively free of plant diseases and therefore prohibits imports. When [[Cyclone Larry]] wiped out Australia's domestic banana crop in 2006, bananas became relatively expensive, due to low supply domestically, and laws prohibiting banana imports.

| + | ===Cultivars of M. acuminata and M. paradisiaca=== |
− | | + | *'''Apple, Silk, or Manzana''' - Dessert type, pleasant sub-acid apple flavor when fully ripe. Fruit: 4 to 6 inches. Grows to 10 to 12 feet. The fruit is not ripe until some brownish specs appear on the skin. From planting until harvest is approximately 15 months. |
− | ==Effects of banana diseases in East Africa== | + | *'''Cavendish''' - Resistant to Panama Wilt disease. Clones of this variety are distinguished by the size of the pseudostem. The largest is Lacatan (12 to 18 feet) followed by Robusta and Giant Cavendish (10 to 16 feet). The smallest is the Dwarf Cavendish (4 to 7 feet). |
− | [[Image:FHIA-17.jpg|thumb|right|Tanzanian farmers with 92 kg (200 lb) bunch of FHIA-17 bananas.]]
| + | *'''Cuban Red''' - Very tall (up to 25 feet), very tropical. Skin dark red, with generally reddish pseudostem. Fruit is especially aromatic with cream-orange pulp. 20 months from planting until harvest. |
− | Most bananas grown worldwide are used for local consumption. In the tropics, bananas, especially cooking bananas, represent a major source of food, as well as a major source of income for smallholder farmers. It is in the East African highlands that bananas reach their greatest importance as a staple food crop. In countries such as [[Uganda]], [[Burundi]] and [[Rwanda]] per capita consumption has been estimated at 450 kg per year, the highest in the world. Ugandans use the same word "matooke" to describe both banana and food.
| + | *'''Gros Michel''' - Commercially, the most important and considered by many to be the most flavorful. Because of its susceptibility to Panama Wilt disease it is being replaced with resistant varieties. Although there is no Panama Wilt in California, it does poorly here as the plant seems to need more heat and it tends to grow more slowly than other varieties |
− | | + | *'''Ice Cream or Blue Java''' - Medium-tall (15 to 20 feet), bluish cast to the unripe fruit. Fruit: 7 to 9 inches, quite aromatic and is said to melt in the mouth like ice cream. Bunches are small with seven to nine hands. 18 to 24 months from planting until harvest. |
− | In the past, the banana was a highly sustainable crop with a long plantation life and stable yields year round. However with the arrival of the [[Black Sigatoka]] fungus, banana production in eastern Africa has fallen by over 40%. For example during the 1970s, Uganda produced 15 to 20 tonnes of bananas per hectare. Today production has fallen to only 6 tonnes per hectare.
| + | *'''Lady Finger''' - Tall (20 to 25 feet), excellent-quality fruit, tolerant of cool conditions. 15 to 18 months from planting to harvest. |
− | | + | *'''Orinoco''' - Commonly grown in California for years as a landscape plant. Grows to 16 feet, more cold hardy than any other. 15 to 18 months from planting to harvest. Flavor is good, texture is less than perfect, but when properly grown and cultivated it can produce enormous stalks of fruit. Excellent in banana bread. Sometimes called horse, hog or burro banana, it can be purchased at most nurseries. |
− | The situation has started to improve as new disease resistant cultivars have been developed such as the [[FHIA-17]] (known in Uganda as the Kabana 3). These new cultivars taste different from the traditionally grown banana which has slowed their acceptance by local farmers. However, by adding [[mulch]] and animal [[manure]] to the soil around the base of the banana plant, these new cultivars have substantially increased yields in the areas where they have been tried.
| + | *'''Popoulu''' - A Hawaiian variety with short, salmon-pink flesh, plump fruit that may be cooked or eaten fresh. A slender plant preferring a protected area with high humidity and filtered light. Grows to about 14 feet tall. |
− | | + | *'''Valery''' - A Cavendish clone resembling the Robusta. Some believe them to be the same. The Dwarf Cavendish is the most widely planted as it is better adapted to a cool climate and is less likely to be blown over. |
− | The [[Rockefeller Foundation]] has started trials for [[genetically modified]] banana plants that are resistant to both Black Sigatoka and banana weevils. It is developing cultivars specifically for smallholder or subsistence farmers.
| + | *'''Williams''' - The same as Giant Cavendish. Originated from a mutation of Dwarf Cavendish found in Queensland, Australia. A commercial banana grown in many countries that does well in California. 10 to 16 feet in height and has a distinctive long, very large bud. The Del Monte is a Williams. |

− | The banana plant has long been a source of fibre for high quality textiles. In Japan, the cultivation of banana for clothing and household use dates back to at least the 13th century. In the Japanese system, leaves and shoots are cut from the plant periodically to ensure softness. The harvested shoots must first be boiled in [[lye]] to prepare the fibres for the making of the yarn. These banana shoots produce fibres of varying degrees of softness, yielding yarns and textiles with differing qualities for specific uses. For example, the outermost fibres of the shoots are the coarsest, and are suitable for tablecloths, whereas the softest innermost fibres are desirable for [[kimono]] and [[kamishimo]]. This traditional Japanese banana cloth making process requires many steps, all performed by hand.<ref>{{cite web |title =Traditional Crafts of Japan - Kijoka Banana Fiber Cloth |publisher = Association for the Promotion of Traditional Craft Industries |date = |url = http://www.kougei.or.jp/english/crafts/0130/f0130.html |accessdate = 11-12-2006}}</ref>

− | In another system employed in Nepal, the trunk of the banana plant is harvested instead, small pieces of which are subjected to a softening process, mechanical extraction of the fibres, bleaching, and drying. After that, the fibres are sent to the [[Kathmandu valley]] for the making of high end rugs with a textural quality similar to silk. These banana fibre rugs are woven by the traditional Nepalese hand-knotted methods, and are sold [[rugmark|RugMark certified]].
