conservation of precious and rare bamboo species in Vietnam<\/strong><\/p>\n

Summary:<\/em><\/strong>Vietnam has a large number (about 100) of bamboo species of which 9 species have been considered as economically valuable and some of them are very rare. These bamboo species are exploited strongly so that their genetic resources are seriously depleted. Some species such as Chimonobambusa quadrangularis<\/em> (Fenzi) Makino, Phyllostachys nigra<\/em> (Lodd.) Munro and P. bambusoides<\/em> Sieb. et Zucc. var. aucro<\/em> Makino are in danger of extinction. Sustainable use and effective conservation measures are needed to save and develop these bamboo resources.<\/p>\n","protected":false},"excerpt":{"rendered":"
