The anatomical morphologies of vessel elements and pits of bamboo plants are unique, however, intensive research about vessel elements and pits in bamboo species is very scarce. The vessel elements and pits of four sympodial bamboo species were analyzed by light microscopy and environmental scanning electron microscopy (ESEM). Results show that the length and width of vessel elements were significantly different across bamboo species. The simple (main type), scalariform, and reticulate perforation plates were discovered on the end of vessel elements. The four species also displayed distinct pit forms. Characteristics of vessel elements, perforation plates, and the shape and size of pit apertures were examined separately for their potential relationship of bamboo structure and function.
竹类植物的导管分子和纹孔的解剖形态具有独特性，然而，对竹种导管分子和纹孔的深入研究却非常匮乏。通过光学显微镜和环境扫描电子显微镜（ESEM）对四种合轴型竹种的导管分子和纹孔进行了分析。结果表明，导管分子的长度和宽度在竹种间存在显著差异。在导管分子的末端发现了简单（主要类型）、梯状和网状穿孔板。这四个物种还表现出明显不同的纹孔类型。分别检查了导管分子、穿孔板以及纹孔口的形状和大小的特征，以研究其与竹结构和功能的潜在关系。
