Banana Test Banana is the common name used for herbaceous plants in the genus Musa, which because of their size and structure, are often mistaken for trees. Bananas are cultivated for their fruit which bear the same name, and to a lesser extent for the production of fibre and as ornamental plants. Bananas are of the family Musaceae. Globally, bananas rank fourth after rice, wheat and maize in human consumption; they are grown in 130 countries worldwide, more than any other fruit crop. Bananas are native to tropical southeastern Asia but are widely cultivated in tropical regions. In popular culture and commerce, "banana" usually refers to the soft, sweet "dessert" bananas that are usually eaten raw. The bananas from a group of cultivars with firmer, starchier fruit, generally used in cooking rather than eaten raw, are typically known as plantains. Bananas may also be dried and ground into banana flour. The main or upright growth is called a pseudostem, which, when mature, will obtain a height of 2–8 m (varies between different cultivars), with leaves of up to 3.5 m in length. Each pseudostem produces a single bunch of bananas, before dying and being replaced by a new pseudostem. The base of the plant is a rhizome (known as a corm). Corms are perennial, with a productive lifespan of 15 years or more. The term banana is applied to both the plant and its elongated fruit (technically a false berry) which grow in hanging clusters, with up to 20 fruit to a tier (called a hand), and 5-20 tiers to a bunch. The total of the hanging clusters is known as a bunch, or commercially as a "banana stem", and can weigh from 30–50 kg. The fruit averages 125 g, of which approximately 75% is water and 25% dry matter content. Bananas are a valuable source of Vitamin A, Vitamin B6, Vitamin C, and potassium. Although the wild species have fruits with numerous large, hard seeds, virtually all culinary bananas have seedless fruits. Bananas are classified either as dessert bananas (meaning they are yellow and fully ripe when eaten) or as green cooking bananas. Almost all export bananas are of the dessert types; however, only about 10-15% of all production is for export, with the U.S. and EU being the dominant buyers. History The domestication of bananas took place in southeastern Asia. Many species of wild bananas still occur in New Guinea, Malaysia, Indonesia and the Philippines. Recent archaeological and palaeoenvironmental evidence at Kuk Swamp in the Western Highlands Province of Papua New Guinea suggests that banana cultivation there goes back to at least 5000 BC, and possibly to 8000 BC. This would make the New Guinean highlands the place where bananas were first domesticated. It is likely that other species of wild bananas were later also domesticated elsewhere in southeastern Asia. The banana is mentioned for the first time in written history in Buddhist texts in 600 BC. Alexander the Great discovered the taste of the banana in the valleys of India in 327 BC. The existence of an organized banana plantation could be found in China in 200 AD. In 650 AD, Islamic conquerors brought the banana to Palestine. Arab merchants eventually spread bananas over much of Africa. The word banana is of West African origin, and passed into English via Spanish or Portuguese. In 15th and 16th century, Portuguese colonists started banana plantations in the Atlantic Islands, Brazil, and western Africa. As late as the Victorian Era, bananas were not widely known in Europe, although they were available via merchant trade. Jules Verne references bananas with detailed descriptions so as not to confuse readers in his book Around the World in Eighty Days (1872). Properties
Trade 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 cultivars. Cooking bananas are very similar to potatoes in how they are used. Both can be 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. 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 FAO statistics. The vast majority of producers are small-scale farmers 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, Del Monte, 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. Cultivation While the original bananas contained rather large seeds, triploid (and thus seedless) cultivars have been selected for human consumption. These are propagated 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 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). Pests and diseases

Fibre 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 done by hand. In another system employed in Nepal, the trunk of the banana plant is instead harvested, small pieces of which are subjected to a softening process, mechanical extraction of the fibres, bleaching, drying, after which 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 certified. Banana fibre is also used in the production of banana paper. Popular culture The depiction of a person slipping on a banana peel has been a staple of physical comedy for generations. A 1906 comedy record produced by Edison Records features a popular character of the time, "Cal Stewart", claiming to describe his own such incident, saying: Because of the stereotypical image of monkeys and apes eating bananas, they have been used for racist insults, such as throwing bananas at sports players of African descent (e.g. *). In Chinese culture, banana is a slang term which is used to describe an Asian person who acts like a caucasian (yellow on the outside, white on the inside). Due to their association with monkeys they are also used as tokens in the 3D Nintendo versions of Donkey Kong and the Sega series Super Monkey Ball. Bananas are also "humorously" used as a phallic symbol due to similarities in size and shape. See also |
