摘　　要：巨龙竹是世界上最大的竹子,该文采用形态标记方法首次系统研究了厚壁型和薄壁型巨龙竹的形态差异。结果证明两者气生根节数与秆壁率二项指标存在显著差异,从而证明了"厚壁型巨龙竹"和"薄壁型巨龙竹"的种质分化,为巨龙竹优良种质资源的选择与发掘提供理论依据。Dendrocalcamus sinicus is the biggest bamboo in the world. It has two typical types,i. e. straight and curved. Recently,thick-walled and thin-walled types have been found. Their morphological differences were studied by using the method of morphological markers. The results showed that the number of node growing aerial roots,and the wall ratio( the inner and outer diameters ratio) differed significantly between these bamboo types. This may provide a theoretical basis for the selection and evaluation of superior germplasm resources.
