In bamboo, as in other grasses, the internodal regions of the [[Biology:Plant stem|stem]] are usually hollow and the [[Biology:Vascular bundle|vascular bundle]]s in the cross-section are scattered throughout the walls of the culm instead of in a cylindrical cambium layer between the bark ([[Biology:Phloem|phloem]]) and the wood ([[Biology:Xylem|xylem]]) as in dicots and conifers. The [[Biology:Dicotyledon|dicotyledon]]ous [[Biology:Woody plant|woody]] [[Biology:Xylem|xylem]] is also absent.

Bamboos have long been considered the most basal grass genera, mostly because of the presence of [[Biology:Bract|bract]]eate, indeterminate inflorescences, "pseudospikelets", and flowers with three [[Biology:Lodicule|lodicule]]s, six stamens, and three [[Biology:Stigma (botany)|stigmata]].<ref name="Clark, LG 1995">{{cite journal |last1= Clark |first1= LG |last2= Zhang |first2= W |last3= Wendel |first3= JF |year= 1995 |title= A Phylogeny of the Grass Family (Poaceae) Based on ndhF Sequence Data |journal= Systematic Botany |volume= 20 |issue= 4 |pages= 436–460 |doi=10.2307/2419803 |jstor= 2419803}}</ref> Following more recent molecular phylogenetic research, many [[Biology:Tribe|tribes]] and genera of grasses formerly included in the Bambusoideae are now classified in other subfamilies, e.g. the [[Biology:Anomochlooideae|Anomochlooideae]], the [[Biology:Puelioideae|Puelioideae]], and the Ehrhartoideae. The subfamily in its current sense belongs to the [[Biology:BOP clade|BOP clade]] of grasses, where it is sister to the [[Biology:Pooideae|Pooideae]] (bluegrasses and relatives).<ref name="GPWGII" />

The bamboos comprise three clades classified as tribes, and these strongly correspond with geographic divisions representing the New World herbaceous species ([[Biology:Olyreae|Olyreae]]), tropical woody bamboos ([[Biology:Bambuseae|Bambuseae]]), and temperate woody bamboos ([[Biology:Arundinarieae|Arundinarieae]]).<ref>{{Citation |last1=Ahmad |first1=Zishan |title=Bamboo: Origin, Habitat, Distributions and Global Prospective |date=2021 |url=https://doi.org/10.1007/978-981-16-1310-4_1 |work=Biotechnological Advances in Bamboo: The “Green Gold” on the Earth |pages=1–31 |editor-last=Ahmad |editor-first=Zishan |access-date=2023-08-29 |place=Singapore |publisher=Springer |language=en |doi=10.1007/978-981-16-1310-4_1 |isbn=978-981-16-1310-4 |last2=Upadhyay |first2=Anamica |last3=Ding |first3=Yulong |last4=Emamverdian |first4=Abolghassem |last5=Shahzad |first5=Anwar |s2cid=239748950 |editor2-last=Ding |editor2-first=Yulong |editor3-last=Shahzad |editor3-first=Anwar}}</ref><ref name="Ayer 100027"/> The woody bamboos do not form a monophyletic group; instead, the tropical woody and herbaceous bamboos are sister to the temperate woody bamboos.<ref name="Kelchner2013"/><ref name="GPWGII"/> Altogether, more than 1,400 species are placed in 115 genera.<ref name="Kelchner2013"/>

==Ecology==
[[File:Bamboo Canopy.jpg|thumb|Bamboo canopy]]
The two general patterns for the growth of bamboo are "clumping", and "running", with short and long underground rhizomes, respectively. Clumping bamboo species tend to spread slowly, as the growth pattern of the rhizomes is to simply expand the root mass gradually, similar to ornamental grasses. Running bamboos need to be controlled during cultivation because of their potential for aggressive behavior. They spread mainly through their [[Biology:Rhizome|rhizome]]s, which can spread widely underground and send up new culms to break through the surface. Running bamboo species are highly variable in their tendency to spread; this is related to the species, [[Chemistry:Soil|soil]] and [[Earth:Climate|climate]] conditions. Some send out runners of several meters a year, while others stay in the same general area for long periods. If neglected, over time, they can cause problems by moving into adjacent areas.

Bamboos include some of the fastest-growing plants on Earth, with reported growth rates up to {{convert|910|mm|in|abbr=on}} in 24 hours.<ref name=Guinness/> These depend on local soil and climatic conditions, as well as species, and a more typical growth rate for many commonly cultivated bamboos in temperate climates is in the range of {{convert|30|–|100|mm|in|frac=2|abbr=on}} per day during the growing period. Primarily growing in regions of warmer climates during the late Cretaceous period, vast fields existed in what is now Asia. Some of the largest timber bamboo grow over {{convert|30|m|ft|sigfig=1|abbr=on}} tall, and be as large as {{convert|250|–|300|mm|in|0|abbr=on}} in diameter. The size range for mature bamboo is species-dependent, with the smallest bamboos reaching only several inches high at maturity. A typical height range covering many of the common bamboos grown in the United States is {{convert|4.5|-|12|m|ft|0|abbr=on}}, depending on species. Anji County of China, known as the "Town of Bamboo", provides the optimal climate and soil conditions to grow, harvest, and process some of the most valued bamboo poles available worldwide.

Unlike all trees, individual bamboo [[Biology:Culm (botany)|culms]] emerge from the ground at their full diameter and grow to their full height in a single [[Biology:Growing season|growing season]] of three to four months. During this time, each new [[Biology:Shoot (botany)|shoot]] grows vertically into a culm with no branching out until the majority of the mature height is reached. Then, the branches extend from the nodes and leafing out occurs. In the next year, the pulpy wall of each culm slowly hardens. During the third year, the culm hardens further. The shoot is now a fully mature culm. Over the next 2–5 years (depending on species), fungus begins to form on the outside of the culm, which eventually penetrates and overcomes the culm.{{citation needed|date=October 2016}} Around 5–8 years later (species- and climate-dependent), the fungal growths cause the culm to collapse and decay. This brief life means culms are ready for harvest and suitable for use in construction within about three to seven years. Individual bamboo culms do not get any taller or larger in diameter in subsequent years than they do in their first year, and they do not replace any growth lost from pruning or natural breakage. Bamboo has a wide range of hardiness depending on species and locale. Small or young specimens of an individual species produce small culms initially. As the clump and its rhizome system mature, taller and larger culms are produced each year until the plant approaches its particular species limits of height and diameter.

Many tropical bamboo species die at or near freezing temperatures, while some of the hardier temperate bamboos survive temperatures as low as {{convert|-29|°C|°F}}. Some of the hardiest bamboo species are grown in [[Hardiness zone|USDA plant hardiness zone]] 5,{{citation needed|date=December 2021}} although they typically defoliate and may even lose all above-ground growth, yet the rhizomes survive and send up shoots again the next spring. In milder climates, such as USDA zone 7 and above, most bamboo remain fully leafed out and green year-round.

=== Mass flowering ===

Bamboos seldom and unpredictably flower and the frequency of flowering varies greatly from species to species. Once flowering takes place, a plant declines and often dies entirely. In fact, many species only flower at intervals as long as 65 or 120 years. These taxa exhibit mass flowering (or gregarious flowering), with all plants in a particular 'cohort' flowering over a several-year period. Any plant derived through clonal propagation from this cohort will also flower regardless of whether it has been planted in a different location. The longest mass flowering interval known is 120 years, and it is for the species ''[[Biology:Phyllostachys bambusoides|Phyllostachys bambusoides]]'' (Sieb. & Zucc.).<ref>{{cite journal |first1=Carl |last1=Veller |first2=Martin A. |last2=Nowak |first3=Charles C. |last3=Davis |date=July 2015 |title=Extended flowering intervals of bamboos evolved by discrete multiplication |url=http://www.people.fas.harvard.edu/~ccdavis/pdfs/Veller_et_al_Ecology_Letters_2015.pdf |journal=Ecology Letters |volume=18 |issue=7 |pages=653–659 |pmid=25963600 |issn=1461-023X |url-status=dead |doi=10.1111/ele.12442 |bibcode=2015EcolL..18..653V |archive-date=2015-09-11 |archive-url=https://web.archive.org/web/20150911202926/http://www.people.fas.harvard.edu/~ccdavis/pdfs/Veller_et_al_Ecology_Letters_2015.pdf}}</ref> In this species, all plants of the same stock flower at the same time, regardless of differences in geographic locations or climatic conditions, and then the bamboo dies.<ref>{{cite book |last=McClure |first=Floyd A. |date=1966 |title=The Bamboos - A Fresh Perspective |isbn=9780674061507 |location=Cambridge, MA |publisher=Harvard University Press |page=274 |url=https://books.google.com/books?id=FlKneBvfDyEC}}</ref> The commercially important bamboo Guadua, or Cana brava (''[[Biology:Guadua angustifolia|Guadua angustifolia]]'') bloomed for the first time in recorded history in 1971, suggesting a blooming interval well in excess of 130 years.{{citation needed|date=January 2023 |reason=Previous source was published in 1966 and could not have reported a 1971 event.}} The lack of environmental impact on the time of flowering indicates the presence of some sort of "alarm clock" in each cell of the plant which signals the diversion of all energy to flower production and the cessation of vegetative growth.<ref name="Soderstrom, TR 1979">{{cite journal |last1=Soderstrom |first1=Thomas R. |last2=Calderon |first2=Cleofe E. |title=A Commentary on the Bamboos (Poaceae: Bambusoideae) |journal=Biotropica |volume=11 |issue=3 |pages=161–172 |year=1979 |doi=10.2307/2388036 |jstor=2388036|bibcode=1979Biotr..11..161S }}</ref> This mechanism, as well as the evolutionary cause behind it, is still largely a mystery.

===General===
{{Excerpt|Bamboo cultivation}}
In Brazil, the [http://www.cebis.org.br Brazilian Center for Innovation and Sustainability - CEBIS], a non-profit organization, promotes the development of Brazil's bamboo production chain. Last year{{When|date=December 2023}}, it helped with the approval of law n~21,162 in the state of Paraná, which encourages Bamboo Culture aiming at the dissemination of its agricultural cultivation and the valorization of bamboo as an instrument for promoting the sustainable socioeconomic development of the State through its multiple functionalities. Bamboo cultivation neutralizes carbon emissions. Bamboo cultivation is cheap and in addition to adding value to its production chain, it is a sustainable crop that brings environmental, economic and social benefits. Its production can be used from construction to food. Recently, it was qualified and classified for the National Commission for Sustainable Development Objectives - CNDOS of the Presidency of the Republic of the federal government of Brazil.

===Harvesting===
[[File:Bamboo Harvesting - Mahimapur - Murshidabad 2017-03-28 6129.JPG|thumb|Bamboo harvested at Murshidabad]]
[[File:Local farmer nearby the park.jpg|thumb|Harvested bamboo transported by river near Ramsai, Jalpaiguri]]

Bamboo used for construction purposes must be harvested when the culms reach their greatest strength and when sugar levels in the [[Biology:Sap|sap]] are at their lowest, as high sugar content increases the ease and rate of pest infestation. As compared to forest trees, bamboo species grow fast. Bamboo plantations can be readily harvested for a shorter period than tree plantations.<ref>{{cite book|title=Non-Wood Forest Products of the Philippines|last1=Razal|first1=Ramon|last2=Palijon|first2=Armando|publisher=El Guapo Printing Press, Calamba Printing Press|year=2009|isbn=978-971-579-058-1|location=Calamba City, Laguna|pages=145}}</ref>

Harvesting of bamboo is typically undertaken according to these cycles:

* '''Lifecycle of the culm''': As each individual [[Biology:Culm (botany)|culm]] goes through a five to seven-year lifecycle, they are ideally allowed to reach this level of maturity prior to full capacity harvesting. The clearing out or thinning of culms, particularly older decaying culms, helps to ensure adequate light and resources for new growth. Well-maintained clumps may have a productivity three to four times that of an unharvested wild clump. Consistent with the lifecycle described above, bamboo is harvested from two to three years through to five to seven years, depending on the species.<ref>{{cite book |last1=Panda |first1=H. |title=Bamboo Plantation and Utilization Handbook |date=Oct 6, 2011 |publisher=Asia Pacific Business Press, Inc. |page=168}}</ref><ref>{{cite news |last1=Marie |first1=Joanne |title=Bamboo Harvesting and Growing |url=https://www.weekand.com/home-garden/article/bamboo-harvesting-growing-18033612.php |agency=Week& |publisher=Hearst Newspapers}}</ref>
* '''Annual cycle''': Most all growth of new bamboo occurs during the wet season and disturbing the clump during this phase will potentially damage the upcoming crop, while harvesting immediately prior to the wet/growth season may also damage new shoots, therefore harvesting is best a few months prior to the start of the wet season.<ref>{{cite web |last1=Hornaday |first1=Fred |title=Harvesting Bamboo: When, why and how |url=https://bambubatu.com/harvesting-bamboo-when-why-and-how/ |website=Bambu Batu|date=22 August 2022 }}</ref> Also during this high-rainfall period, sap levels are at their highest, and then diminish towards the [[Earth:Dry season|dry season]].<ref>{{cite journal |last1=Hasan |first1=S.M. |title=STUDIES ON GROWTH AND MATURITY OF BAMBOO CULMS |journal=The Commonwealth Forestry Review |date=June 1975 |volume=54 |issue=2 |pages=147–153}}</ref>
* '''Daily cycle''': During the height of the day, [[Earth:Photosynthesis|photosynthesis]] is at its peak, producing the highest levels of sugar in sap, making this the least ideal time of day to harvest and many traditional practitioners believe the best time to harvest is at dawn or dusk on a waning moon.<ref>{{cite web |last1=Schröder |first1=Stéphane |title=When and How to Harvest Bamboo |url=https://www.guaduabamboo.com/blog/when-and-how-to-harvest-bamboo |publisher=Guadua Bamboo}}</ref>

===Leaching===
Leaching is the removal of sap after harvest. In many areas of the world, the sap levels in harvested bamboo are reduced either through leaching or post-harvest photosynthesis.
For example:
* Cut bamboo is raised clear of the ground and leaned against the rest of the clump for one to two weeks until leaves turn yellow to allow full consumption of sugars by the plant.
* A similar method is undertaken, but with the base of the culm standing in fresh water, either in a large drum or stream to leach out sap.
* Cut culms are immersed in a running stream and weighted down for three to four weeks.
* Water is pumped through the freshly cut culms, forcing out the sap (this method is often used in conjunction with the injection of some form of treatment).

In the process of water leaching, the bamboo is dried slowly and evenly in the shade to avoid cracking in the outer skin of the bamboo, thereby reducing opportunities for pest infestation.

Durability of bamboo in construction is directly related to how well it is handled from the moment of planting through harvesting, transportation, storage, design, construction, and maintenance. Bamboo harvested at the correct time of year and then exposed to ground contact or rain will break down just as quickly as incorrectly harvested material.<ref>{{cite web |last1=Myers|first1=Evan T.|title=Structural Bamboo Design in East Africa|url=https://www.academia.edu/5108420|publisher=[[Organization:Kansas State University|Kansas State University]]|access-date=18 June 2014|url-status=live|archive-url=https://web.archive.org/web/20161216111453/http://www.academia.edu/5108420/Structural_Design_of_Bamboo_in_East_Africa|archive-date=16 December 2016}}</ref>

== Toxicity ==
Gardeners working with bamboo plants have occasionally reported allergic reactions varying from no effects during previous exposures, to immediate itchiness and rash developing into red welts after several hours where the skin had been in contact with the plant (contact allergy), and in some cases into swollen eyelids and breathing difficulties (dyspnoea).

The shoots of most species are edible either raw or cooked, with the tough sheath removed. Cooking removes the slight bitterness.<ref name="Skyhorse Publishing-2009">{{Cite book |title=The Complete Guide to Edible Wild Plants / Department of the Army |publisher=Skyhorse Publishing |year=2009 |isbn=978-1-60239-692-0 |location=New York |pages=24 |oclc=277203364}}</ref> The shoots are used in numerous Asian dishes and broths, and are available in supermarkets in various sliced forms, in both fresh and canned versions.

The bamboo shoot in its fermented state forms an important ingredient in cuisines across the Himalayas. In Assam, India, for example, it is called ''khorisa''.<ref>{{Cite web|date=2020-07-18|title=Bamboo Shoots – Khorisa|website=FarmToRasoi|url=https://www.farmtorasoi.com/bamboo-shoots/|access-date=2021-12-17|archive-date=17 December 2021|archive-url=https://web.archive.org/web/20211217143632/https://www.farmtorasoi.com/bamboo-shoots/|url-status=dead}}</ref> In Nepal, a delicacy popular across ethnic boundaries consists of bamboo shoots fermented with [[Biology:Turmeric|turmeric]] and oil, and cooked with potatoes into a dish that usually accompanies rice ({{transliteration|ne|alu tama}}<ref>{{Cite web|title=Alu tama {{!}} Traditional Soup From Nepal |website=TasteAtlas |url=https://www.tasteatlas.com/alu-tama |access-date=2021-12-17}}</ref> ({{lang|ne|आलु तामा}}) in [[Social:Nepali language|Nepali]]).

In Indonesia, they are sliced thin and then boiled with ''santan'' (thick coconut milk) and spices to make a dish called ''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). 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 [[Biology:Pith|pith]] of the young shoots.

The sap of young stalks tapped during the rainy season may be fermented to make ''ulanzi'' (a sweet wine)<ref>{{Cite web |title=Ulanzi (Bamboo Wine)|website=elkinvanaeon.net |url=http://elkinvanaeon.net/Alchemy/Brewed_Beverages/ulanzi_bamboo-wine.htm |access-date=2021-12-17}}</ref> or simply made into a soft drink.<ref>{{Cite web |last=Hallgren |first=Steve |date=2018-07-22 |title=Ulanzi: The Miracle Drink of Tanzania |website=Teaching High School Biology in Tanzania: A Peace Corps Volunteer Experience |url=https://hellofrompeacecorpstanzania.wordpress.com/category/mufindi-highlands-in-iringa-region/ulanzi-the-miracle-drink-of-tanzania/ |access-date=2021-12-17}}</ref> Bamboo leaves are also used as wrappers for steamed dumplings which usually contains glutinous rice and other ingredients, such as the zongzi from China.

Pickled bamboo shoots ({{lang-ne|तामा|link=no}} {{transliteration|ne|tama}}) are cooked with black-eyed beans as a delicacy in Nepal. Many Nepalese restaurants around the world serve this dish as ''aloo bodi tama''. Fresh bamboo shoots are sliced and pickled with mustard seeds and turmeric and kept in glass jar in direct sunlight for the best taste. It is used alongside many dried beans in cooking during winters. Baby shoots ([[Social:Nepali language|Nepali]]: ''tusa'') of a very different variety of bamboo ({{lang-ne|निगालो|link=no}} {{transliteration|ne|Nigalo}}) native to Nepal is cooked as a curry in hilly regions.

In Sambalpur, India, the tender shoots are grated into juliennes and fermented to prepare ''kardi''. The name is derived from the Sanskrit word for bamboo shoot, ''karira''. This fermented bamboo shoot is used in various culinary preparations, notably ''amil'', a sour vegetable soup. It is also made into pancakes using [[Biology:Rice flour|rice flour]] as a binding agent.<ref>{{Cite web |title=Kardi bhaja / Bamboo shoot cutlets Recipe by Sona Senapati|url=https://cookpad.com/uk/recipes/15265917-kardi-bhaja-bamboo-shoot-cutlets|access-date=2021-12-17|website=Cookpad|date=14 July 2021 |language=en}}</ref> The shoots that have turned a little fibrous are fermented, dried, and ground to sand-sized particles to prepare a garnish known as ''hendua''. It is also cooked with tender pumpkin leaves to make sag green leaves.

In Konkani cuisine, the tender shoots (''kirlu'') are grated and cooked with crushed jackfruit seeds to prepare ''kirla sukke''.

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. Similarly, steamed tea is sometimes rammed into bamboo hollows to produce compressed forms of pu'er tea. Cooking food in bamboo is said to give the food a subtle but distinctive taste.

==== Writing surface ====
Bamboo was in widespread use in early China as a medium for written documents. The earliest surviving examples of such documents, written in ink on string-bound bundles of bamboo strips (or "slips"), date from the fifth century BC during the Warring States period. References in earlier texts surviving on other media indicate some precursor of these Warring States period bamboo slips was used as early as the late Shang period (from about 1250 BC).

Bamboo or wooden strips were used as the standard writing material during the early Han dynasty, and excavated examples have been found in abundance.<ref>{{cite book |last=Loewe |first=Michael |title=New Sources of Early Chinese History |publisher=Society for the Study of Early China |year=1997 |isbn=978-1-55729-058-8 |editor=Edward L. Shaughnessy |pages=161–192 |chapter=Wood and bamboo administrative documents of the Han period}}</ref> Subsequently, [[History:History of paper|paper]] began to displace bamboo and wooden strips from mainstream uses, and by the fourth century AD, bamboo slips had been largely abandoned as a medium for writing in China.

Bamboo fiber has been used to make paper in China since early times. A high-quality, handmade bamboo paper is still produced in small quantities. Coarse bamboo paper is still used to make [[Biology:Joss paper|spirit money]] in many Chinese communities.<ref name="spiritpaper">{{cite journal |last1=Perdue |first1=Robert E. |last2=Kraebel |first2=Charles J. |author3=Tao Kiang |date=April 1961 |title=Bamboo Mechanical Pulp for Manufacture of Chinese Ceremonial Paper |journal=Economic Botany |volume=15 |issue=2 |pages=161–164 |doi=10.1007/BF02904089 |s2cid=9556185}}</ref>

Bamboo [[Chemistry:Pulp (paper)|pulps]] are mainly produced in China, Myanmar, Thailand, and India, and are used in [[Chemistry:Printing and writing paper|printing and writing paper]]s.<ref name="Market pulp">{{cite book |last=Nanko |first=Hirko |title=The World of Market Pulp |author2=Button, Allan |author3=Hillman, Dave |publisher=WOMP, LLC |year=2005 |isbn=978-0-615-13013-2 |location=Appleton, WI, US |page=256}}</ref> Several paper industries are surviving on bamboo forests. Ballarpur (Chandrapur, Maharstra) paper mills use bamboo for paper production. The most common bamboo species used for paper are ''[[Biology:Dendrocalamus asper|Dendrocalamus asper]]'' and ''[[Biology:Bambusa blumeana|Bambusa blumeana]]''. It is also possible to make [[Chemistry:Dissolving pulp|dissolving pulp]] from bamboo. The average fiber length is similar to hardwoods, but the properties of bamboo pulp are closer to [[Engineering:Softwood|softwood]] pulps due to it having a very broad fiber length distribution.<ref name="Market pulp" /> With the help of molecular tools, it is now possible to distinguish the superior fiber-yielding species/varieties even at juvenile stages of their growth, which can help in unadulterated merchandise production.<ref>{{cite book |last=Bhattacharya |first=S. |title=Tropical Bamboo: Molecular profiling and genetic diversity study |publisher=Lambert Academic Publishing |year=2010 |isbn=978-3-8383-7422-2}}</ref>

In Central India, there are regular bamboo working circles in forest areas of Maharashtra, Madhyapradesh, Odisha and Chhattisgarh. Most of the bamboo is harvested for papermaking. Bamboo is cut after three years of its germination. No cutting is done during the rainy season (July–September); broken and malformed culms are harvested first.<ref name="Working Plan">{{cite book |last1=Shrivastav |first1=S.S. |url=https://mahaforest.gov.in/managementpdf/1440739682Chandrapur%20Vol-I.pdf.pdf |title=Working Plan for Chandrapur Forest Division |date=3 December 2002 |publisher=Govt. of Maharashtra |location=Nagpur |access-date=23 December 2020}}</ref>

==== Writing pen ====

In olden times, people in India used hand-made pens (known as Kalam or boru (बोरू)) made from thin bamboo sticks (with diameters of 5–10&nbsp;mm and lengths of 100–150&nbsp;mm) by simply peeling them on one side and making a nib-like pattern at the end. The pen would then be dipped in ink for writing.<ref>{{Cite journal|last=Sengupta|first=Rajarshi|date=2019-01-02|title=An Artisanal History of Kalam?|url=https://doi.org/10.1080/20511787.2019.1580437|journal=Journal of Textile Design Research and Practice|volume=7|issue=1|pages=25–37|doi=10.1080/20511787.2019.1580437|s2cid=190517335|issn=2051-1787}}</ref>

==== Textiles ====

Since the fibers of bamboo are very short (less than {{convert|3|mm|in|frac=32|abbr=on|disp=or}}), they are not usually transformed into yarn by a natural process. The usual process by which textiles labeled as being made of bamboo are produced uses only [[Chemistry:Rayon|rayon]] made from the fibers with heavy employment of chemicals. To accomplish this, the fibers are broken down with chemicals and extruded through mechanical spinnerets; the chemicals include [[Chemistry:Lye|lye]], [[Chemistry:Carbon disulfide|carbon disulfide]], and strong acids.<ref name="Scientific American">{{cite journal |author=Michelle Nijhuis |date=June 2009 |title=Bamboo Boom: Is This Material for You? |journal=Scientific American Earth 3.0 Special |volume=19 |issue=2 |pages=60–65 |doi=10.1038/scientificamericanearth0609-60}}</ref> Retailers have sold both end products as "bamboo fabric" to cash in on bamboo's current ecofriendly cachet.

In China and India, bamboo was used to hold up simple suspension bridges, either by making cables of split bamboo or twisting whole culms of sufficiently pliable bamboo together. One such bridge in the area of Qian-Xian is referenced in writings dating back to 960 AD and may have stood since as far back as the third century BC, due largely to continuous maintenance.{{citation needed|date=January 2018}}<ref>{{Cite journal |last=Maheshwari |first=Rohit |date=2019 |title=Comparison of bonding behaviour of bamboo reinforcement in concrete beam using bonding material |url=https://www.researchgate.net/publication/357932584 |journal=International Journal of Engineering Science and Computing |volume=9 |issue=5 |pages=21937 |via=Research Gate}}</ref>

In the Philippines, the nipa hut is a fairly typical example of the most basic sort of [[Engineering:House|housing]] where bamboo is used; the walls are split and woven bamboo, and bamboo slats and poles may be used as its support.

In Japanese architecture, bamboo is used primarily as a supplemental or decorative element in buildings such as fencing, fountains, grates, and gutters, largely due to the ready abundance of quality timber.<ref name="BambooJapan">{{cite book

Many ethnic groups in remote areas that have water access in Asia use bamboo that is 3–5 years old to make rafts. They use 8 to 12 poles, {{convert|6|–|7|m|ft|0|abbr=on}} long, laid together side by side to a width of about {{convert|1|m|ft|0|abbr=on}}. Once the poles are lined up together, they cut a hole crosswise through the poles at each end and use a small bamboo pole pushed through that hole like a screw to hold all the long bamboo poles together. Floating houses use whole bamboo stalks tied together in a big bunch to support the house floating in the water.

==== Fishing and aquaculture ====
[[File:Abucay,Bataanjf3721 06.JPG|thumb|Bamboo trays used in [[Biology:Mussel|mussel]] farming (Abucay, Bataan, Philippines)]]
Due to its flexibility, bamboo is also used to make [[Engineering:Fishing rod|fishing rod]]s. The split cane rod is especially prized for [[Engineering:Fly fishing|fly fishing]].

==== Firecrackers ====
Bamboo has been traditionally used in Malaysia as a firecracker called a ''meriam buluh'' or [[Engineering:Bamboo cannon|bamboo cannon]]. Four-foot-long sections of bamboo are cut, and a mixture of water and [[Chemistry:Calcium carbide|calcium carbide]] are introduced. The resulting acetylene gas is ignited with a stick, producing a loud bang.

==== Weapons ====
Bamboo has often been used to construct weapons and is still incorporated in several Asian martial arts.
* A bamboo staff, sometimes with one end sharpened, is used in the Tamil martial art of ''silambam'', a word derived from a term meaning "hill bamboo".
* Staves used in the Indian martial art of ''gatka'' are commonly made from bamboo, a material favoured for its light weight.
* A bamboo sword called a ''shinai'' is used in the Japanese martial art of ''kendo''.
* Bamboo is used for crafting the bows, called ''[[Engineering:Yumi|yumi]]'', and arrows used in the Japanese martial art ''kyūdō''.
* The first [[Chemistry:Gunpowder|gunpowder]]-based weapons, such as the [[Engineering:Fire lance|fire lance]], were made of bamboo.
* Sharpened bamboo [[Engineering:Javelin|javelin]]s weighted with sand known as ''bagakay'' were used as disposable missile weapons in both land and naval warfare in the Philippines. They were thrown in groups at a time at enemy ships or massed enemy formations. Non-disposable finely-crafted throwing spears made from bamboo weighted with sand known as ''sugob'' were also used. ''Sugob'' were mainly used for close-quarters combat and were only thrown when they could be retrieved.<ref name="scott">{{cite book|author=William Henry Scott|title =Barangay.

Bamboo's long life makes it a Chinese symbol of uprightness and an Indian symbol of friendship. The rarity of its [[Biology: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 [[Biology:Mautam|Mautam]]).

In Chinese culture, the bamboo, [[Biology:Prunus mume|plum]] blossom, [[Biology:Orchid|orchid]], and [[Biology:Chrysanthemum|chrysanthemum]] (often known as ''méi lán zhú jú'' {{lang|zh|梅蘭竹菊}} in Chinese) are collectively referred to as the Four Gentlemen. These four plants also represent the four seasons and, in [[Philosophy:Confucianism|Confucian]] ideology, four aspects of the ''[[Philosophy:Junzi|junzi]]'' ("prince" or "noble one"). The [[Biology:Pine|pine]] (''sōng'' {{lang|zh|松}}), the bamboo (''zhú'' {{lang|zh|竹}}), and the plum blossom (''méi'' {{lang|zh|梅}}) are also admired for their perseverance under harsh conditions, and are together known as the "Three Friends of Winter" ({{Lang-zh|c=歲寒三友|p=suìhán sānyǒu|labels=no}}) in Chinese culture.

Bamboo, one of the "Four Gentlemen" (bamboo, orchid, plum blossom and chrysanthemum), plays such an important role in traditional Chinese culture that it is even regarded as a behavior model of the gentleman. As bamboo has features such as uprightness, tenacity, and modesty, people endow bamboo with integrity, elegance, and plainness, though it is not physically strong. Countless poems praising bamboo written by ancient Chinese poets are actually metaphorically about people who exhibited these characteristics. An ancient poet, Bai Juyi (772–846), thought that to be a gentleman, a man does not need to be physically strong, but he must be mentally strong, upright, and perseverant. Just as a bamboo is hollow-hearted, he should open his heart to accept anything of benefit and never have arrogance or prejudice.

Bamboo is not only a symbol of a gentleman, but also plays an important role in Buddhism, which was introduced into China in the first century. As canons of Buddhism forbids cruelty to animals, flesh and egg were not allowed in the diet. The tender bamboo shoot (''sǔn'' {{lang|zh|筍}} in Chinese) thus became a nutritious alternative. Preparation methods developed over thousands of years have come to be incorporated into Asian cuisines, especially for monks. A Buddhist monk, Zan Ning, wrote a manual of the bamboo shoot called ''Sǔn Pǔ'' ({{lang|zh|筍譜}}) offering descriptions and recipes for many kinds of bamboo shoots.<ref>Laws, B. 2010. Bamboo. ''Fifty Plants that Changed the Course of History''. New York:Firefly Books (U.S) Inc.</ref> Bamboo shoot has always been a traditional dish on the Chinese dinner table, especially in southern China.
In ancient times, those who could afford a big house with a yard would plant bamboo in their garden.

==== Mythology ====
In a Chinese legend, the Emperor Yao gave two of his daughters to the future Emperor Shun as a test for his potential to rule. Shun passed the test of being able to run his household with the two emperor's daughters as wives, and thus Yao made Shun his successor, bypassing his unworthy son. After Shun's death, the tears of his two bereaved wives fell upon the bamboos growing there explains the origin of [[Biology:Spotted bamboo|spotted bamboo]]. The two women later became goddesses [[Biology:Xiangshuishen|Xiangshuishen]] after drowning themselves in the Xiang River.

Bamboo is a symbol of prosperity in Japan, and are used to make New Year's decorations called ''[[Religion:Kadomatsu|kadomatsu]]''. Bamboo forests sometimes surround Shinto shrines and Buddhist temples as part of a sacred barrier against [[Philosophy:Evil|evil]]. In the folktale ''Tale of the Bamboo Cutter'' (''Taketori Monogatari''), princess Kaguya emerges from a shining bamboo section.

In Japan, the Chinese "Three Friends of Winter" (''kansai sanyū'') concept is traditionally used as a ranking system, where pine ({{lang|ja|松}} ''matsu'') is the first rank, bamboo ({{lang|ja|竹}} ''take'') is the second rank, and plum ({{lang|ja|梅}} ''ume'') is the third rank. This system is used in many traditional arts like with sushi sets, embroidering kimono or tiers of accommodations at traditional ''ryōkan'' taverns.

Bamboo plays an important part of the culture of Vietnam. 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 adaptability. A Vietnamese proverb says, "Tre già, măng mọc" (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. Traditional Vietnamese villages are surrounded by thick bamboo hedges (''lũy tre'').

During Ngô Đình Diệm's presidency, bamboo was the national symbol of South Vietnam, it was featured on the national coat of arms, presidential standard, and South Vietnamese đồng coins at the time.

==== Mythology ====
A bamboo cane is also the weapon of Vietnamese legendary hero, Thánh Gióng, who had grown up immediately and magically since the age of three because of his wish to liberate his land from Ân invaders. The ancient Vietnamese legend ''Cây tre trăm đốt'' (The Hundred-knot Bamboo Tree) 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 100 nodes". But [[Biography:Gautama Buddha|Gautama Buddha]] (''Bụt'') appeared to the farmer and told him that such a tree could be made from 100 nodes from several different trees. ''Bụt'' gave to him four magic words to attach the many nodes of bamboo: ''Khắc nhập, khắc xuất'', which means "joined together immediately, fell apart immediately". The triumphant farmer returned to the landlord and demanded his daughter. Curious to see such a long bamboo, the landlord was magically joined to the bamboo when he touched it, as the young farmer said the first two magic words. The story ends with the happy marriage of the farmer and the landlord's daughter after the landlord agreed to the marriage and asked to be separated from the bamboo.
