Missouri Botanical Garden, St. The plant and its origin This variety was initially identified as belonging to the Bambusas until when the German botanist Karl S. Bambusa Mutis ex Caldasillegitimate homonym not Schreb. Before introducing the reeds in the dissolution, all the internodes of the reeds are perforated, on the one hand this facilitates the immersion because it allows the air to escape from the inside of the reeds and the reed stops acting as a float, and on the other hand it allows the entry of the mixture into the different sections of the reed, thus ensuring a correct preservation because the bamboo is much more permeable from the inside.
On the basis of such studies, Japan and the Netherlands have both undertaken massive forestation projects as a way of earning so-called “carbon kunfh to offset industrial pollution [ citation needed ].
Another important protection to take into account is to avoid direct contact with sources of moisture because, although the Guadua includes a complete treatment against fungi kunty xylophages, the great variations of humidity inside can end up producing cracks. Highly appreciated by Simon Bolivar for its watershed protection and praised by Alexander von Humboldt for its wide variety of uses [ citation needed ]it is being used in construction today in South America.
For architectural purposes, Guadua is the preferred bamboo species. Vegetal materials in construction. During the first 6 months they grow at a very high rate, which can reach 15 cm per day until reaching their final height of 20 to 30 m. To prevent the bamboo from being attacked by xylophagous insects and to prevent fungal growth, the canes are immersed for days in a solution of borax and boric acid at a ratio guwdua 1: Or, Guadua can be propagated more rapidly by the chusquin method.
The high percentage of fibre present in its structure and the high content of silica in its outer face make this species present the angustifolix characteristics of resistance and flexibility that characterize it.
Physically, Guadua angustifolia is noted for being the largest Neotropical bamboo. Environmentally, Guadua is more effective at removing carbon dioxide from the atmosphere than most other tropical forest [ citation needed ] ; ongoing studies in Colombia have now anghstifolia coordinated by the Environmental Bamboo Foundation.

These features have attracted the attention of civil gudauaarchitectsacademicsdesigners, and artists. The genus can be found in a wide range from northern Mexico and Trinidad to Guadaubut most of the species are concentrated in the Amazon basin and the Orinoco basin. Bamboo propagated in a laboratory in the space of one square meter will be angjstifolia to establish one hectare of new forest.
This is avoided in the structures by adding footings or any other element that lifts the piece and allows rainwater to drain away.
Several animals are, to a various extent, associated angustfolia stands of Guadua bamboo, for example several species of seedeatersand the Amazon and Atlantic Bamboo Rats. In the vines can reach more than 3 cm, used in pillars or where a lot of work is received by compression while in the bases can be between 0.
Biennale of Architecture In other projects Wikimedia Commons Wikispecies. For structural applications of Bamboo, whenever angistifolia it is preferable to prevent the sun from shining directly on the canes by protecting the structure by design, including eaves in the project and not leaving the ends exposed.

The genus is similar to Bambusa and is sometimes included in that genus. University of Southern California. Technical studies of bamboo’s mechanical properties “vegetable steel” angustifoia increased interest in its use.
Tropical bamboo can be propagated with cuttings or guadus covering complete culms with soil. As an added advantage, all materials treated in this way have fire-resistant properties thanks to borax. Among the characteristics of the Guadua is its extraordinary firmness to compression and a good resistance to the parallel cut, this added to the great flexibility that presents turn the Guadua cane into a guaduua especially interesting for the bioconstruction, where this catalogued as structural material seismic-resistant.
Guadua capitata — Eremocaulon capitatum Guadua exaltata — Arthrostylidium longiflorum Guadua flabellata — Chusquea bilimekii Guadua pallescens — Bambusa tuldoides Guadua parviflora — Aulonemia parviflora Guadua perligulata — Chusquea perligulata Guadua philippinensis — Sphaerobambos philippinensis. Guadua is a Neotropical genus of thorny, clumping bamboo qngustifolia the grass familyranging from moderate to very large species. Due to its quality, the genus has been widely used for house construction along the inter-Andean rivers of Colombia and in coastal Ecuador.
Angustifoliia the following years the plant will contribute biomass to the soil, fixing environmental CO2 and developing its woody structure.
Recent earthquakes in Colombia’s coffee zone demonstrated this when many houses built in the s survived, while modern houses collapsed [ citation needed ]. Its diameter is constant for the first 15 meters and then tapers at the top. A checklist of the basal grasses and bamboos in Brazil Poaceae. The reeds obtained from the highest section, called Sobrebasa, have thin walls but maintain a high fiber content. If it is necessary to hide these cracks, either for aesthetic reasons or to facilitate the cleaning of the structure itself, the ideal is to cover them with the same flexible putties used in wood, since it is usual that with an increase in humidity the openings close again.
This variety was initially identified as belonging to the Bambusas until when the German botanist Karl S. This is a phenomenon not known in tropical hardwood forests [ citation needed ]. Protection by Design and Maintenance When building with bamboo on the outside as with any timber it is necessary to take into account the action of the sun on the surface of the reeds.
Recent studies conducted by the European Union indicate that bamboo has relatively low water requirements and that its root system is an excellent watershed protector [ citation needed ]. There is a great amount of life inside, with a multitude of plants, mammals, birds and reptiles associated with them. In addition, regular and controlled exploitation favours the development of Guadual as a whole and stimulates its natural regeneration.
They usually grow at low altitudes below 1, mbut has been found up to 2, m. When building with bamboo on the outside as with any timber it is necessary to take into account the action of the sun on the surface of the reeds. The intermediate sections or Basas are slender and very light in relation to their enormous strength, maintain the outer diameter very well and are very fibrous so they are the most used parts in construction, especially in the manufacture of beams and composite trusses.
Its habitats include lowland tropical and lower-montane forest, savannasCerradosgallery forest, and disturbed inter-Andean valley vegetation. Guadua Guadua angustifolia Scientific classification Kingdom: Japanese garden Villa Torii by Ramses Life.
