Volumetric estimate of bordered pits in Pinus sylvestris based on X-ray tomography and light microscopy imaging.

摘要: Bordered pits are a major determinant for the hydraulic function of wood tissues. Unlike microscopic imaging (e.g. light and electron microscopy) that is constrained to two-dimensional (2D) information, X-ray micro-computed tomography (XμCT) contributes three-dimensional (3D) analysis. This advantage was used estimate volume bordered in Pinus sylvestris. The 3D data obtained by XμCT were compared with two mathematical models (ellipsoid model spherical cap model) using 2D transmission microscopy XμCT. findings this study showed approximation ellipsoid revealed values close volumes, which three-dimensionally trend, however, more pronounced earlywood than latewood. Nevertheless, demonstrated images can also be pit volumes some extent. Researchers should aware limitations come method resolution, image analysis) (unknown location section pit) as well natural variation morphology.
