Culm wall
WebJan 1, 2015 · The culm wall is covered on both sides with a special tissue (Fig. 8.1 ). Its outer part, the cortex, presents a watertight seal to prevent any moisture loss of the living culm. The structural composition of compact fiber bundles with thick walls provides also a protection against mechanical wounding. WebA bamboo culm consists of nodes and internodes. Internodes are generally hollow and cylindrical. The internodes have a culm wall surrounding a large cavity, called lacuna. In the internodes, the cells are strongly axially oriented [12]. Culm wall is mainly composed of parenchymatous ground tissue in which vascular bundles are embedded [12,13].
