【摘要】 对６属１７种丛生竹竹材进行了比较解剖研究。结果表明，不同类型竹种的内部解剖构造存在明显差异，主要是维管束的形态及密度。供试竹种中竹杆维管束类型主要有紧腰型和断腰型两大类，其中断腰型又可细分为花竹亚型、信宜石竹亚型、黄麻竹亚型和大琴丝竹亚型。通过对竹材内部解剖特征的分析比较，发现不同用途竹种的内部结构也存在一定差异。结合竹子分类，提出了一些参考意见。更多还原

【Abstract】 Anatomical structure of bamboo wood for 17 species of tufted bamboos is 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 albo lineata subtype,B.subtruncata subtype,Dendrocalamopsis stenoaurita subtype,and Neosinocalamus affinis subtype.Different usages of bamboos with their special structure are discussed.更多还原
