Comparative anatomy on seventeen species of tufted bamboos

Anatomical structure of bamboo wood for 17 species of tufted bamboos was studied. The result indicates that there are many differences in internal structure (mainly in shape and density of vascular bundle) among different bamboo species. Vascular bundle of bamboo wood can be divide into two types: slender waist and broken waist. The latter can be classified deeply as four subtypes: Bambusa albolineata subtype, B. subtruncata subtype, Dendrocalamopsis stenoaurita subtype, and Neosinocalamus affinis subtype. Different usages of bamboos with theeir special structure are discussed.
