''Bambusa vulgaris'', common bamboo, is an open-clump type bamboo species. It is native to Indochina and to the province of Yunnan in southern China, but it has been widely cultivated in many other places and has become naturalized in several.〔(Kew World Checklist of Selected Plant Families )〕〔Dieter Ohrnberger, ''The bamboos of the world'', pages 279-280, Elsevier, 1999, ISBN 978-0-444-50020-5〕 Among bamboo species, it is one of the largest and most easily recognized.〔''Biology Pamphlets'' (Volume 741), page 15, University of California, 1895〕〔D. Louppe, A.A. Oteng-Amoako and M. Brink, ''Timbers'' (vol. 1), pages 100-103, PROTA, 2008, ISBN 978-90-5782-209-4〕 ==Description== ''Bambusa vulgaris'' forms moderately loose clumps and has no thorns.〔Flora of North America Editorial Committee, ''Magnoliophyta: Commelinidae'', page 22, Oxford University Press, 2007, ISBN 978-0-19-531071-9〕 It has lemon-yellow culms (stems) with green stripes and dark green leaves.〔(''Bambusa vulgaris'' ), OzBamboo; Retrieved: 2007-12-19〕 Stems are not straight, not easy to split, inflexible, thick-walled, and initially strong.〔(Babusa vulgaris ), Protabase, Plant Resources of Tropical Africa〕 The densely tufted culms grow high and thick.〔〔A. N. Rao, V. Ramanatha Rao and John Dransfield, ''Priority species of bamboo and rattan'', page 25, Bioversity International, 1998, ISBN 978-92-9043-491-7〕 Culms are basally straight or flexuose (bent alternately in different directions), drooping at the tips. Culm walls are slightly thick.〔(Bambusa vulgaris ), Flora of China, eFloras.com〕 Nodes are slightly inflated. Internodes are . Several branches develop from mid-culm nodes and above. Culm leaves are deciduous with dense pubescence.〔 Leaf blades are narrowly lanceolate.〔 Flowering is not common, and there are no seeds. Fruits are rare due to low pollen viability caused by irregular meiosis.〔 At the interval of several decades, the whole population of an area blooms at once,〔W. Arthur Whistler, ''Tropical ornamentals: a guide'', pages 77-78, Timber Press, 2000, ISBN 978-0-88192-475-6〕 and individual stems bear a large number of flowers.〔 Vegetation propagates through clump division, by rhizome, stem and branch cutting, layering, and marcotting.〔〔D. Louppe, A.A. Oteng-Amoako and M. Brink (edit.), ''Timbers 1'' (Volume 7), PROTA, 2008, ISBN 978-90-5782-209-4〕 The easiest and most practised cultivation method is culm or branch cutting. In the Philippines, the best results were obtained from one-node cuttings from the lower parts of six-month-old culms.〔 When a stem dies, the clump usually survives.〔 A clump can grow out of stem used for poles, fences, props, stakes, or posts.〔 Its rhizomes extend up to 80 cm before turning upward to create open, fast-spreading clumps.〔 The easy propagation of ''B. vulgaris'' explains its seemingly wild occurrence.〔 The average chemical composition is cellulose 41–44%, pentosans 21–23%, lignin 26–28%, ash 1.7–1.9%, and silica 0.6–0.7%.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Bambusa vulgaris」の詳細全文を読む スポンサード リンク
