一、前言种子植物维管束的构造很早就是划分双子叶植物与单子叶植物的重要依据,但具体应用到竹子的系统分类却是经过了很多年的探索。竹类维管束解剖结构的研究已有近百年的历史,在本世纪三十年代日本学者竹内叔雄、宇野昌一都作了很好的工作,宇野昌一作了11个属54个种与变种的竹子维管束解剖,并把竹子维管束分为α_1、α_2、β_1、β_2、β_3、γ计三类六型,其中γ型就 I. Introduction The structure of vascular bundles of seed plants is an important basis for the division of dicotyledons and monocotyledons long ago. However, the systematic classification applied to bamboo has been explored for many years. The research on the anatomical structure of bamboo vascular bundles has been nearly a hundred years. In the 1930s, Japanese scholar Takeuchi Takehiro and Yoichi Umino worked very well. Yu Yichang made 11 genus 54 species and varieties The vascular bundles of bamboo were anatomized, and the vascular bundles of bamboo were divided into three types and six types of α_1, α_2, β_1, β_2, β_3 and γ,
