Microscopic Structure of Yellow Bamboo (

A faster harvest period compared to wood, along with bamboo’s crucial ecological role as a rapidly growing plant that efficiently absorbs carbon and accumulates biomass in a short time and contributes significantly to global climate change mitigation. This study aims to determine the anatomical properties of yellow bamboo at the base, middle, and tip. The anatomical properties were observed using 2 cm ring samples from each position. Samples were macerated using the FPL method. Cell proportions and fiber dimension were observed with a microscope. Cell proportions were calculated using the dot grid method, and fiber dimensions were measured using ImageJ. Data were analyzed using ANOVA. The average proportion of vascular bundles at the base, middle, and tip were 57.52%, 57.46%, and 56.65%. Average fiber length, diameter, lumen, and wall thickness were 2.8 mm, 13.68 μm, 5.45 μm, and 4.12 μm. The ANOVA test results showed no significant effect of axial position on anatomical properties and derivative values. The derived value is 300 (Class II) indicates yellow bamboo fibers are suitable for pulp and paper with good folding strength and not easily torn. This research provides essential baseline data to support sustainable bamboo industry development, community utilization, and future scientific studies.
