Summary
Dendrocalamus asper or commonly known as Giant Bamboo or Rough Bamboo is a very large, dense-clumping, evergreen species native to Southeast Asia. It grows up to 20 m tall and 12 cm in diameter. Younger plants are covered with fine velvety brown hairs. The nodes are swollen; younger nodes have many aerial roots while middle and upper nodes have branches. It is widely cultivated for its highly valued culms that are used as building material and its shoots that are used as vegetable. Upper internodes of the culm are used as containers for water or to collect juice being tapped from palm inflorescence. It can be grown from rhizomes, culm or branch cuttings.

Edible Uses
Young stems - cooked. Free of bitterness[ 310 ]. Harvested before they emerge from the soil, they are tender and sweet[ 301 , 310 ]. They are used as a vegetable, pickled or preserved[ 301 ]. They can be cut into strips and used as a substitute for macaroni in soups[ 301 ]. The edible portion of young shoots is about 34%; they weigh on average 5.4 kilos before peeling and 1.8 kilos after peeling[ 299 ].

Other Uses
Other Uses: The upper internodes of the culm, which are longer than the lowermost ones, are used as containers for water or to collect juice being tapped from palm inflorescences[ 310 ]. The internodes of this and other bamboo species are also used as ready-made cooking pots in the field[ 299 , 310 ]. The internode is opened at one end (or the node) and filled with vegetables, meat or rice, and water, and is then covered and placed on a fire[ 310 ]. The culms have thick walls and are very strong and durable. They are used as building material for houses and bridges, for making furniture, boards, musical instruments, household utensils, crafts, outriggers of fishing boats and for paper making[ 299 , 310 ].

A plant of moist areas in the tropics and subtropics, where it can be found from low elevations up to 1,500 metres, though it grows best at an elevation of 400 - 500 metres[ 310 , 418 ]. It grows best in areas where annual daytime temperatures are within the range 20 - 27?c, but can tolerate 15 - 34?c[ 418 ]. It prefers a mean annual rainfall in the range 1,800 - 3,600mm, but tolerates 1,200 - 4,500mm[ 418 ]. Succeeds in any type of soil of at least moderate fertility, though it grows better on heavy soils with good drainage[ 310 , 418 ]. In Thailand, according to local farmers, the plant will grow well on sandy and rather acidic soils[ 310 ]. Prefers a pH in the range 5 - 6.5, tolerating 4.5 - 7[ 418 ]. Bamboos have an interesting method of growth. Each plant produces a number of new stems annually - these stems grow to their maximum height in their first year of growth, subsequent growth in the stem being limited to the production of new side branches and leaves. In the case of some mature tropical species the new stem could be as much as 30 metres tall, with daily increases in height of 30cm or more during their peak growth time. This makes them some of the fastest-growing species in the world[ K ]. Initially, a young plant raised from a lateral branch cutting will produce small shoots which will develop into small culms[ 310 ]. As the plant grows older, so the culms produced each year increase in size and quantity until full-size culms appear five or six years after planting[ 310 ]. A mature clump may attain a diameter of 3 metres or more and contains about 60 culms[ 310 ]. A culm becomes mature when 3 - 4 years old[ 310 ]. A good healthy clump can produce several shoots annually[ 310 ]. Yields of 10 - 11 tonnes per hectare of bamboo shoots have been reported from Thailand[ 418 ]. Bamboos in general are usually monocarpic, living for many years before flowering, then flowering and seeding profusely for a period of 1 - 3 years before usually dying. This species usually flowers when around 100 - 120 years old[ 299 ].
Propagation
Seed - sow in containers and only just cover. Germination usually takes place readily. Prick out into individual pots as soon as the plants are large enough to handle. Plant out into permanent positions when 20cm tall. Plants may remain in their low-growing juvenile state for several years - cutting the culms to the ground level can stimulate taller adult growth[ 200 ]. Rhizome, culm and branch cuttings[ 310 ]. The propagules are raised in the nursery and after they have produced roots they are planted out in the field before or during the first half of the rainy season[ 310 ].
