Abstract Density is one of the important physical indicators of bamboo, associated with its many physical and mechanical properties. The temporal and spatial variation of density in 2-5-year-old Dendrocalamus farinosus were measured using computed tomography (CT) technology. Scanning parameters were obtained through orthogonal design. The relationship of air-dry density (Y) and the corresponding CT values (X) was established and verified through regression analysis, which presents an approximate linear relationship between them. The linear equation is Y=0.001X+1.148. The radial and longitudinal variation of density was determined by the regression model. This study provides a new method to measure bamboo density efficiently and accurately, and also put forward a new thought to further study structure and characteristics of bamboo.
