'''Bamboo''' is a group of [[wood]]y [[perennial plant|perennial]] [[evergreen]] [[plant]]s in the [[true grass]] family '''[[Poaceae]]''', subfamily [[Bambusoideae]], tribe '''Bambuseae'''. Some of its members are giants, forming by far the largest members of the grass family. New shoots of some of the larger species can grow over 1 meter per day. They are of high cultural significance in [[East Asia]] where they are used extensively in gardens, as a building material as well as a food source. In [[Japanese (language)|Japanese]] they are known as {{nihongo|'''''take'''''|[[Kanji]]: [[wikt:竹|竹]]; [[Hiragana]]: たけ}}, in [[Chinese (language)|Chinese]] as '''''zhu''''' ({{zh-cp|c=竹|p=zhú}}) and '''''Tre''''' {{IPA|/tʃe/}} in [[Vietnamese language|Vietnamese]].

There are 91 genera and about 1,000 species of bamboo. They are found in diverse climates, from cold mountains to hot [[tropical]] regions. They occur across [[East Asia]], from 50°N latitude in [[Sakhalin]] through to northern [[Australia]], and west to [[India]] and the [[Himalaya]].<ref>N. Bystriakova, V. Kapos, I. Lysenko and C.M.A. Stapleton.

Major areas with no native bamboos include [[Europe]], north [[Africa]], western [[Asia]], [[Canada]], most of [[Australia]], and [[Antarctica]].

==Cultivation==

===Commercial timber===
Timber is harvested from cultivated and wild stands and some of the larger bamboos, particularly species in the genus ''[[Phyllostachys]]'', are known as "timber bamboo."

===Ornamental bamboos===
Many bamboos are popular in cultivation as [[garden]] plants. In cultivation, care needs to be taken of their potential for invasive behavior. They spread mainly through their [[root]]s and/or [[rhizomes]], which can spread widely underground and send up new culms to break through the surface. There are two patterns for the growth of bamboo, "clumping" (sympodial) and "running" (monopodial). Clumping bamboo species tend to spread slowly as the growth pattern of the rhizomes is to simply expand the root mass gradually; they do not send out runners. Running bamboo species are highly variable in their tendency to spread; this is related to both the species and the [[soil]] and [[climate]] conditions. Some can send out runners several meters a year, while others can stay in the same general area for long periods. If neglected, they can be invasive over time and can cause problems by moving into adjacent areas. The reputation of bamboo as being highly invasive is often exaggerated, and situations where it has taken over large areas is often the result of years of untended or neglected plantings.

Once established as a grove, it is difficult to completely remove bamboo without digging up the entire network of underground rhizomes. If bamboo must be removed, an alternative to digging it up is to cut down the culms, and then repeatedly mow down new shoots as they arise, until the root system exhausts its energy supply and dies. If any leaves are allowed to photosynthesize, the bamboo survives and will keep spreading.

There are two main ways to prevent the spread of running bamboo into adjacent areas. The first method is rhizome pruning or "edging," which involves removing any rhizomes escaping the desired bamboo area. Pruning shears, shovels, and pickaxes are useful tools for this task. The rhizomes are generally very close to the surface(usually within a foot), so, if rhizome pruning is done twice a year, it will sever most, if not all, of the new growth. Some species may be deep running (beyond typical spade depth). These are much harder to control and deeper cuts will need to be made. Regular maintenance will indicate major growth directions and locations. Once the rhizomes are cut they are typically removed; however, rhizomes take a number of months to establish themselves independent of the main plant, and an immature, severed rhizome will usually cease growing if left in-ground. If any bamboo shoots come up outside of the bamboo area afterwards, their presence indicates the precise location of the missed rhizome. The fibrous roots that radiate from the rhizomes do not grow up to be more bamboo so they stay in the ground.

The second way to control growth is by surrounding the plant or grove with a physical barrier. Concrete and specially rolled HDPE plastic are usual materials. This is placed in a 60-90 cm (2-3 feet) deep ditch around the planting, and angled out at the top to direct the rhizomes to the surface. Strong rhizomes and tools can penetrate plastic barriers with relative ease, so great care must be taken. Bamboo in barriers is much more difficult to remove than free-spreading bamboo.
Barriers and edging are unnecessary for clump forming bamboos. Clump forming bamboos may eventually need to have portions taken out if they get too large.

==Uses==
===Culinary uses===
[[Image:TakenokoBambooSprouts.jpg|right|thumb|300px|Edible bamboo shoots in a Japanese market]]

{{main|Bamboo shoot}}
The shoots (new bamboo culms that come out of the ground) of bamboo, called ''zhú sǔn'' (simplified: [[wikt:竹|竹]][[wikt:笋|笋]]; traditional: [[wikt:竹|竹]][[wikt:筍|筍]]) or simply ''sǔn'' ([[wikt:笋|笋]]) in [[Chinese language|Chinese]], are edible. They are used in numerous Asian dishes and broths, and are available in supermarkets in various sliced forms, both fresh and canned version. Bamboo shoot tips are called ''zhú sǔn jiān'' ([[wikt:竹|竹]][[wikt:笋|笋]][[wikt:尖|尖]]) or simply ''sǔn jiān'' ([[wikt:笋|笋]][[wikt:尖|尖]]).

In [[Indonesia]] they are sliced thinly and then boiled with ''santan'' (thick coconut milk) and spices to make a dish named ''[[gulai rebung]]''. Other recipes using bamboo shoots are ''[[sayur lodeh]]'' (mixed vegetables in coconut milk) and ''lun pia'' (sometimes written ''[[lumpia]]'': fried wrapped bamboo shoots with vegetables). Note that the shoots of some species contain toxins that need to be leached or boiled out before they can be eaten safely.

Pickled bamboo, used as a condiment, may also be made from the [[pith]] of the young shoots.

The sap of young stalks tapped during the rainy season may be fermented to make ''ulanzi'' (a sweet wine) or simply made into a soft drink. ''Zhúyèqīng jiǔ'' (竹葉青酒) is a green-coloured [[Baijiu|Chinese liquor]] that has bamboo leaves as one of its ingredients.

Bamboo leaves are also used as wrappers for ''[[zongzi]]'', a steamed dumpling typical of southern [[China]], which usually contains glutinous rice and other ingredients.

Bamboo is used in Chinese medicine for treating infections. It is also a low calorie source of potassium. In [[Ayurveda]], a Indian system of traditional medicine, the silicious concretion found in the culms of the bamboo stem is called ''banslochan''. It is known as ''tabashir'' or ''tawashir'' in ''Unani-Tibb'' the Indo-Persian system of Medicine. In English this concretion is called "bamboo manna". This concretion is said to be a tonic for the respiratory diseases. This concretion, which was earlier obtained from ''Melocanna bambusoides ''is very hard to get now and has been largely replaced by synthetic silcic acid. (In most of the Indian literature, ''Bambusa arundinacea'' has been shown to be the source of bamboo manna.) (Puri, 2003)

The empty hollow in the stalks of larger bamboo is often used to cook food in many Asian cultures. Soups are boiled and rice is cooked in the hollows of fresh stalks of bamboo directly over a flame. As well, steamed tea is sometimes rammed into bamboo hollows to produce [[compressed tea|compressed forms]] of [[Pu-erh tea]].

In ''[[Sambalpur]]'', India,the tender shoots are grated into julliens and fermented to prepare KARDI also synonymous with Bamboo Shoots the name is derieved from the Sanskrit word for Bamboo Shoot "KARIRA". This fermented Bamboo Shoot is used various culinary preparation notably "Amil" a sour vegetable soup. It is also made into pan cakes using ''[[Rice]]'' flour as a binding agent along with spices and condiments to prepare a side dish in the local main meal. The Shoots that has turned a little fibrous is fermented dried and grounded to sand size particles to prepare a garnish known as " Hendua". It is also cooked with tender ''[[Pumpkin]]'' leaves to make Sag "Green Leaves'.

When treated, bamboo forms a very hard wood which is both light and exceptionally durable. In tropical climates it is used in elements of house construction, as well as for fences, bridges, toilets, walking sticks, canoes, tableware, furniture, [[chopstick]]s, food steamers, toys, construction scaffolding, as a substitute for steel reinforcing rods in [[concrete]] construction, hats, and [[martial arts]] weaponry, including [[fire arrow]]s, [[flame thrower]]s and [[Rocket Festival|rockets]]. Also, [[abacus|abaci]] and various musical instruments such as the [[dizi]], [[Xiao (flute)|xiao]], [[shakuhachi]], [[palendag]], [[jinghu]], and [[angklung]]. The [[Bamboo Organ]] of [[Las Pinas]], [[Philippines]] has pipes made of bamboo culms. When bamboo is harvested for wood, care is needed to select mature stems that are several years old, as first-year stems, although full size, are not fully developed and are not as strong as more mature stems.

Bamboo is also widely carved for decorative artwork. Modern companies are attempting to popularize [[bamboo flooring]] made of bamboo pieces steamed, flattened, glued together, finished, and cut. However, bamboo wood is easily infested by wood-boring insects unless treated with wood preservatives or kept very dry (see carving, right).

Bamboo canes are normally round in cross-section, but square canes can be produced by forcing the new young culms to grow through a tube of square cross-section slightly smaller than the culm's natural diameter, thereby constricting the growth to the shape of the tube. Every few days the tube is removed and replaced higher up the fast-growing culm.

The fibre of bamboo has been used to make [[paper]] in [[China]] since early times. A high quality hand-made paper is still produced in small quantities. Coarse bamboo paper is still used to make [[Joss paper|spirit money]] in many Chinese communities.

The wood is used for [[knitting]] needles and the fibre can be used for [[yarn]] and [[fabrics]]. Bamboo fabric is notable for its soft feel and natural antibacterial properties.<ref>http://leladesigns.ca/fabric-faqs.php</ref> Clothing made from bamboo fibre is popular for activities such as [[yoga]]. Bed sheets and towels made from bamboo have become luxury items{{Fact|date=February 2007}}. Sharpened bamboo is also traditionally used to tattoo in Japan, Hawaii and elsewhere.

Bamboo is used for the stems of traditional Chinese and Japanese [[smoking pipe]]s, and was also utilized for crafting the stems of [[opium pipes]].

A variety of species of bamboo was one of about two dozen plants carried by [[Polynesia]]n voyagers to provide all their needs settling new islands; in the [[Hawaiian Islands]], among many uses, 'Ohe (bamboo) carried water, made irrigation troughs for [[taro]] terraces, was used as a traditional knife for cutting the umbilical cord of a newborn, as a stamp for dyeing bark [[tapa cloth]], and for four [[hula]] instruments — nose flute, rattle, stamping pipes and [[Jew's harp]].

Some skateboard, snowboard deck manufacturers as well as surfboard builders are beginning to use bamboo construction. It is both lighter and stronger than traditional materials and its cultivation is environmentally friendly. At least one snow ski manufacturing company, [[Liberty Skis]], now uses bamboo construction for these reasons.<ref>[http://www.freeskier.com/freeskier/news.php?news_id=903 ''Freeskier Magazine''] (February 26, 2007)</ref>

Bamboo is also used to make enclosures in fish farming, where cages can be made from a wooden frame and bamboo lattices. It is also used to make the high-end lightweight fishing rods used in [[fly fishing]].

A single shoot of Bamboo can also be made into a [[didgeridoo]], a wind instrument that is indigenous to Australia.

Bamboo has gained increasing popularity in the culinary world as a material for cutting boards, as they are hard enough to withstand years of knife abuse, yet more forgiving to the knife blade, causing less damage to the edged utensils over time.

In [[Indonesia]], bamboo has been used for making various kinds of musical instruments. The most popular ones are [[kolintang]] and [[angklung]]. Especially for angklung, it is the pride and joy of the [[Sundanese]] people, and they have been safeguarding this tradition for centuries. Although, it is (in a lesser extent) also played by the [[Balinese]], and later on spread to the neighboring countries in south east Asia.

In [[Vietnam]], bamboo is the material to make a lot of houseware: table and chair, basket, rá, giần, sàng, fishing rod, bè, lantern, kite, [[chông]]- a kind of weapon, house, bamboo bridge which're only bamboo tree-trunk width...and some kinds of musical instrument: [[đàn tranh]], [[đàn bầu]]... Bamboo's grown in range as natural walls to protect Vietnamese villages from their enemies and to keep soil from [[Red River (Vietnam)]] floods' erosion. Bamboo duramen soup which's a medicine is a Vietnamese precious imperial meal.

[[Image:Hsü Wei 001.jpg|thumb|Bamboo, by [[Xu Wei]] in [[Ming Dynasty]].]]
Bamboo's long life makes it a Chinese symbol of longevity, while in [[India]] it is a symbol of friendship. The rarity of its [[bamboo blossom|blossoming]] has led to the flowers' being regarded as a sign of impending famine. This may be due to rats feeding upon the profusion of flowers, then multiplying and destroying a large part of the local food supply. The most recent flowering began in May [[2006]] (see [[Mautam]]). Bamboo is said to bloom in this manner only about every 50 years (see 28&ndash;60 year examples in [http://www.fao.org/documents/show_cdr.asp?url_file=/docrep/x5390e/x5390e05.htm 'gregarious' species table]).

In Chinese culture, the bamboo (''zhú'' 竹), [[plum]] blossom (''[[mei|méi]]'' 梅), [[orchid]] (''lán'' 蘭), and [[chrysanthemum]] (''jú'' 菊) (usually, ''méi lán zhú jú'' 梅蘭竹菊) are collectively referred to as the Four Noble Ones (四君子). These [[four]] [[plants]] also represent the four [[season]]s and, in [[Confucius|Confucian]] ideology, four aspects of the [[junzi]] (君子 "prince" or "noble one"). The [[pine]] tree (松), the bamboo, and the plum blossom (''sōng zhú méi'' 松竹梅) are also admired for their perseverance under harsh conditions, and are together known as the "Three Friends in Winter" (歲寒三友).

In [[Japan]], a bamboo forest sometimes surrounds a Shinto [[Jinja (Shinto)|shrine]] as part of a sacred barrier against [[evil]]. Many Buddhist temples also have bamboo groves. Also, bamboo (''také'' 竹) indicates something of the second rank, (as a [[sushi]] set or accommodations at a traditional [[Ryokan (inn)]]). This comes from the Chinese phrase 松竹梅 (in Japanese, ''sho-chiku-bai''), where [[pine]] (''matsu'' 松) is of the first rank, and plum (''ume'' 梅) is of the third.

In the [[Chinese calligraphy|calligraphy]] of Zhang's style, the poem ''Returning to My Farm in the Field'' by the 4th century poet [[Tao Yuanming]] is incised on the holder.]]
Bamboo symbolizes the spirit of [[Vovinam]] (a Vietnamese martial arts): "cương nhu phối triển" (coordination between [[hard and soft (martial arts)]]). Bamboo also symbolizes the Vietnamese hometown and Vietnamese soul: the gentlemanlike, straightforwardness, hard working, optimism, unity and adaptableness. Furthermore, some scientists even regard that Vietnamese culture is bamboo culture. A Vietnamese proverb says: "When the bamboo is old, the bamboo sprouts appear", the meaning being [[Vietnam]] will never be annihilated; if the previous generation dies, the children take their place. Therefore the Vietnam nation and Vietnamese value will be maintained and developed eternally.

The [[Song Dynasty]] ([[960]]-[[1279]] AD) Chinese scientist and [[polymath]] [[Shen Kuo]] ([[1031]]-[[1095]]) used the evidence of underground [[petrified]] bamboo found in the dry northern climate of [[Yan'an]], [[Shanbei]] region, [[Shaanxi]] province to support his [[geological]] theory of gradual [[climate change]].<ref name="chan 15">Chan, Alan Kam-leung and Gregory K.

===Myths and legends===
Several Asian cultures, including that of the [[Andaman Islands]], believe that humanity emerged from a bamboo stem. In the [[Philippines|Philippine]] creation myth, legend tells that the first man and the first woman were split open from a bamboo stem that emerged on an island created after the battle of the elemental forces (Sky and Ocean). In [[Malaysia]]n legends a similar story includes a man who dreams of a beautiful woman while sleeping under a bamboo plant; he wakes up and breaks the bamboo stem, discovering the woman inside. The Japanese folktale "[[Tale of the Bamboo Cutter]]" (''Taketori Monogatari'') tells of a princess from the Moon emerging from a shining bamboo section. [[Hawaiian Islands|Hawaiian]] bamboo ('ohe) is a kinolau or body form of the Polynesian creator god [[Kāne Milohai]].

[[Image:Bamboo bonsai Chengdu.jpg|thumb|Bamboo [[bonsai]]]]
Bamboo cane's also the weapon of Vietnamese legendary hero [[Thánh Gióng]]- who had grown up immediately and magically since the age of 3 years old because of his national liberating wish against [[Ân invaders]].

An ancient Vietnamese legend tells of a poor, young farmer who fell in love with his landlord's beautiful daughter. The farmer asked the landlord for his daughter's hand in marriage, but the proud landlord would not allow her to be bound in marriage to a poor farmer. The landlord decided to foil the marriage with an impossible deal; the farmer must bring him a "[[bamboo tree of one-hundred sections]]". The benevolent god [[Bụt]] appeared to the farmer and told him that such a tree could be made from one-hundred sections from several different trees. Bụt gave to him four magic words to attach the many sections of bamboo: "Khắc nhập, khắc xuất", which means "put in immediately, take out immediately". The triumphant farmer returned to the landlord and demanded his daughter. The story ends with the happy marriage of the farmer and the landlord's daughter.

==Other Aspects==
[[Image:Panda1.jpg|thumb|right|Bamboo is the main food of the [[Giant Panda]]; it makes up 99% of the Panda's diet.]]
Soft bamboo shoots, stems, and leaves are the major food source of the [[Giant Panda]] of [[China]].

The plant marketed as "lucky bamboo" is actually an entirely unrelated species, ''[[Dracaena sanderiana]]''.

[[Bamboo charcoal]] is made of bamboo by [[pyrolysis]] process.
