基于X射线三维可视化和定量分析小麦籽粒的萌芽

    3D Visualization and Quantitative Analysis of Internal Structure of Wheat Kernel Sprouting Using X-Ray Micro-Computed Tomography

    • 摘要: 利用X射线断层扫描法无损地研究了小麦籽粒萌芽后内部结构的变化,实现了小麦籽粒萌芽后部分特征的三维可视化和定量分析。利用图像滤波、阈值分割、重建算法对X射线断层扫描获取的图像进行重建和渲染,实现了萌芽籽粒精确的三维可视化表征,除了可视化外还获取了如体积、表面积、孔隙等形态学参数。通过分析发现籽粒萌芽时变化最大的是籽粒的胚部,其次是盾片和胚乳,胚乳在被酶分解供给胚部营养时,先分解的是盾片和糊粉层附近的胚乳,然后从盾片处胚乳逐渐向腹沟处分解。X射线断层扫描是一种强有力的工具,可用于无损检测单颗小麦籽粒等生物材料的损伤和微观结构组织。

       

      Abstract: Micro X-ray computer tomography was used to assess the internal components of wheat kernel non-destructively.This paper described the 3D visualization and quantitative analysis of the internal features of Wheat kernel after damage caused by sprouting.Micro X-ray CT images were reconstructed and processed using image processing algorithms.Imaging processing techniques such as segmentation and thresholding were used to render visualization modules such as volume rendering and geometric reconstruction.In addition to visualization,morphometric parameters such as volume,area surface,porosity were determined.It was found that the most significant change in seed sprouting was the embryo,followed by scutellum and endosperm.When the endosperm was decomposed by enzymes to supply the nutrients to the embryo,the endosperm near the scutellum and the aleurone layer was first decomposed,and then the endosperm was gradually decomposed from the scutellum to the ventral groove.X-ray tomography is a powerful tool for the non-invasive investigation of damage,and microstructure organization in biological materials such as single wheat kernels.
