Background and Objective: Bamboo culm was composed of internodes and nodes. Anatomically, bamboo culm was composed of vascular bundles (VB) and parenchymal base tissue. The purpose of this study was to determine the morphology features of culm and VB of bamboo Gigantochloa apus. Materials and Methods: The sample was taken from each internode of bamboo. The morphology of bamboo culm was determined by measuring the length, diameter and wall thickness. VB characterization was obtained through observation on each internode of bamboo culm. Results: The results showed that bamboo culm had internode length and inner diameter that varied from the bottom, increased at a certain height then decreased toward the top. The size of outer diameter and wall thickness of bamboo culm tended to decrease from bottom to top. VB on each internode was spread unevenly where the distance between VB looked more widened from the outer layer to the inner layer. VB distribution in the cross section had a crossing pattern (alternate). VB varied in shape and size from outer layer to inner layer of bamboo culm. The VB type on an internode of G. apus bamboo culm also showed variations where there was VB in type III only and some also were in type (III and IV) in each internode. Conclusion: The morphology of the bamboo culm was influenced by the morphology of young shoot. VB of bamboo G. apus spread unevenly with varying sizes, shapes and type from the outer layer to the inner layer.
