BAMBOO

Bamboo is a tribe of flowering perennial evergreen plants.
They are some of the fastest-growing plants in the world. They are of
notable economic and cultural significance in South Asia, Southeast Asia
and East Asia, being used for building materials, as a food source, and as a
versatile raw product.
Bamboo species are found in diverse climates, from cold mountains to hot
tropical regions.
There are over 1600 species of bamboo, 64 percent of which are native to
Southeast Asia. 33 percent grows in Latin America, and the rest in Africa
and Oceania.

Bamboo is one of the fastest-growing plants on Earth, with reported
growth rates of 100 cm (39 in) in 24 hours. However, the growth rate
is dependent 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 3–10 centimeters (1.2–3.9 in)
per day during the growing period.
Primarily growing in regions of warmer climates, vast fields existed in
what is now Asia. Some of the largest timber bamboo can grow over
30 m (98 ft) tall, and be as large as 15–20 cm (5.9–7.9 in) in diameter.

TYPES
There are two types of bamboo with approximately 1500 species.
There are two main forms: the economically and ecologically important
woody bamboos and the understory herbaceous bamboos.
Molecular analysis of the suggests that there are 3-5 major lineages
of bamboo. Four major lineages are recognized: temperate woody,
paleotropical woody, neotropical woody and herbaceous bamboos.

USES
Bamboo is useful for different things at different ages:
<30 days it is good for eating
6-9 months for baskets
2-3 years for bamboo boards or laminations
3-6 years for construction
>6 years bamboo gradually loses strength up to 12 years old
Bamboo, like true wood, is a natural composite material with high
strength-to-weight ratio useful for structures.
In its natural form, bamboo as a construction material is traditionally
associated with the cultures of South Asia, East Asia and the South
Pacific, to some extent in Central and South America.
Bamboo's tensile strength has been essential in the development of
bridges. In China and India, bamboo was used to hold up simple
suspension bridges, either by making cables of split bamboo or twisting
whole culms (individual bamboo stems) of sufficiently pliable bamboo
together. Using only the exterior part of the bamboo, which is four
times as strong as the interior, the Chinese created tension cables up
to 120 meters long. Bamboo bridges were also by the Incas in South
America.
