Bamboo (Bambusoideae) of the grass family (Poaceae) include some of the fastest-growing plants in the world; certain species of bamboo can grow 900 mm within 24 hours. There are more than 1,400 species of bamboo, placed in 116 genera.
Bamboo plays an integral part in Chinese culture, both economically and culturally. Before the invention of paper, ancient China first wrote their text on bamboo stripes, and the writing brushes have a bamboo shaft to hold the hairs. Bamboo is omnipresent in China because of its availability, lightness, strength and flexibility: buildings, musical instruments, weapons, farm tools, and cooking utensils. Papermaking uses pulp from bamboo, and the modern textile industry make bamboo rayon by dissolving the cellulose in the bamboo and then extruded to form fibres.
